There are tens of millions of domains registered all of the world and every day thousands of these domains expires. Many of these expired domains have history of high traffic to their websites. Such domains may have had thousands of links on popular search engines or listed on popular directories such as Yahoo or DMOZ and may have high ranking on sites such as Alexa. Building such traffic is time consuming and may take years. In addition, listing on directories such as Yahoo can cost $299.0 for mainstream site or $599.0 for adult sites. Though, Yahoo has free submission to noncommercial categories, but there is no guarantee and it may take several months. Yahoo receives on average 15000 submissions per day to these noncommercial categories, thus there is very long waiting period.
PlexDomain provides a toolset to search, analyze, monitor and register popular on-hold and deleted domains. It allows users to search deleted, on-hold, and registered domains. Users can check traffic for these sites from dozens of popular search engines and directories such as Yahoo, DMOZ, AltaVista, Lycos, etc. Users can specify criteria for accepting domains, such as the sites that must exist in Yahoo-Directory or DMOZ-Directory category or have a minimum of N links to them or have a minimum of X rating on Alexa website. These searches can be done in foreground or as a scheduled job which runs in background. This scheduled job can be run on regular interval automatically. The scheduled job creates a detailed report and can email report to the user when done.
Following is list of major benefits offered by PlexDomain:
PlexDomain allows users to search domains that are:
· Deleted
· On-Hold
· Real-Time Newly-Deleted
· Expiring Soon
· Available for Registration
· Registered Domains
The user can specify criteria for selecting domains such as keywords, length of domains or if they contain numbers or hyphens. These domains are then used by filtering process that selects popular domains.
PlexDomain allows users to browse lists of real-time newly domains. The user can specify additional criteria for selecting domains such as length of domains or if they contain numbers or hyphens. These domains are then used by filtering process that selects popular domains.
PlexDomain allows users to schedule a job that crawls Yahoo or DMOZ directory and searches for expired domains on each category. It then stores the expired domains and reports results back to the user.
Once user has list of domains he searched from either keyword-search or deleted lists, he/she can then check those domains in popular search engines and directories. User can select the number of links for each domain in:
· AltaVista
· AllTheWeb
· Teoma
· Alexa
· AOL
· HotBot
· Lycos
· DMOZ
· LookSmart
· MSN
· Yahoo
The user can specify minimum number of links to accept, or if they must exist in Yahoo, DMOZ or LookSmart or minimum ranking of site on Alexa website. PlexDomain will then search all these domains and automatically purge all domains which do not meet criteria and highlight popular domains.
PlexDomain allows users to specify a list of keywords, top-level-domains with a set of prefix and suffix words and it generates all possible domain names. It then checks each of those domains against whois server and shows list of available domains. The user can also schedule a background job, which searches for available domains and then saves those domains.
PlexDomain allows users to schedule background jobs to check for the availability of domains on regular basis. It then shows status of those domains and emails the results to the users.
PlexDomain allows users export and import domains from list of domains to analyze. In addition, user can type-in data. These domains can be then used by filtering process that selects popular domains.
PlexDomain uses multi-threading for searching and filtering domains, where each search is run in its own thread. This improves overall throughput for processing domains and reduce bottlenecks from serial processing.
PlexDomain caches results of web searches. Thus, when a user performs the same search it will be done much quickly. The cache results are kept for one or two days and can also be cleared by the user.
PlexDomain allows users to schedule a search or filtering task, which is run in background. The user can specify one-time or recurring batch jobs which are run on regular interval. The results of these batch jobs are automatically stored in a local file and a detailed HTML-based report is created. The user can choose an option to receive this report automatically when the job is completed. This allows users to schedule a job to search for newly-deleted domains and store popular domains for later viewing.
PlexDomain allows users to search for whois-records for registered or soon-to-expire domains. It also parses whois-records and identifies important information such as contact, registration date, expiration date, etc.
PlexDomain shows up-to-date statistics of number of domains that are registered, on-hold and deleted.
PlexDomain allows users to view multiple searches at the same time.
PlexDomain allows user to check popularity of an user-entered domain in various search engines and directories.
PlexDomain allows user to check ranking of any domain using a specify keywords. Users can track ranking of their favorite sites using this tool.
PlexDomain allows user to check popularity of various keywords and suggest similar keyword and their popularity.
PlexDomain shows real-time keyword searches performed by the users on various search engines and shows top keywords at various search engines.
PlexDomain comes with links to a number of popular resources for registering, monitoring or back-tracking domains.
PlexDomain comes with links to a number of online resources related to trademark and standardization organizations.
PlexDomain allows user to lookup a host-name in a naming service.
PlexDomain allows users to view public information stored in Whois database for a particular host.
Some large ISPs also support Rwhois protocol to provide public information on their clients. PlexDomain allows users to search that public information for a particular host.
Whois only allows search by host-name, many ISPs do not provide host-name for some IP-Addresses. Arin, Ripe, and other similar databases allow users to find owners of IP-addresses. PlexDomain has a smart algorithm to automatically use correct database for any IP-address user enters and shows public information of IPS.
PlexDomain allows user to find list of mail servers for a particular host.
PlexDomain allows user to find SOA record for a particular host.
PlexDomain supports a facility to translate text between following languages:
· English
· Chinese
· French
· German
· Italian
· Japanese
· Korean
· Spanish
· Portoguese
· Pig Latin
· ROT13
PlexDomain provides multiple tools to search people and their email addresses. First, it allows users to use predefined or user-provided LDAP servers to search people. Second, it allows users to search people using Yahoo’s search. Third it allows users to search users in usenet database. The results of search can be easily imported into the address book.
PlexDomain allows users to search for all sub-domains of a particular site, which are listed on common search engines.
PlexDomain allows users to search for all similar sites for a particular site, which are listed on common search engines.
PlexDomain allows users to search for all sites, which have a link to the user-specified, which are listed on common search engines.
PlexDomain software is written purely in Java and it can be run on any platform where Java virtual machine is available. The installations for various platforms are available from:
http://www.plexobject.com/software/plexdomain/download.html
After downloading the appropriate
installation file, follow the directions at the website for installation.
Before using this software, it helps to understand the domain lifecycle. A domain’s lifecycle starts with the domain registration. A typical registration lasts for one-year. When the expiration date approaches, the owner receives a renewal notice. If the owner registers the domain before expiration, it remains registered. However if the owner fails to register, it is considered expired domain. A typical expiration period lasts from 1-45 days and registrar deletes the domain from its registry. After the domain is deleted from the registry, the email and website will no longer be accessible. After expiration, the domain is granted some redemption period of 30-days. The owner can still renew his/her domain during this. After this domain is permanently deleted which may take up-to fie days? After the domain is permanently deleted, it becomes available for registration by other people.

PlexDomain is fully graphical based application, which supports multiple document interface for viewing multiple searches at the same time. The figure 2 shows the main screen, where drop-down menus are placed at top, followed by toolbar, and then one or more search windows.

The first thing user will need to do is select domains. There are five primary mechanisms for searching domains:
The option allows users to search domains by specifying keywords. In addition, user can narrow criteria by length of the domain or whether it can contain hyphens or numbers. To search keyword search, select
Domain->New->Domain Search
option from drop down menu.
These options
allow users to search for most-valued domains. The value of a domain depends on
its length, whether domain includes any numbers or hyphens, and most
importantly brand. A strong, clear domain free of ties to other
sites/businesses is the most valuable.

Select type of domains that you wish you choose. User can search domains that are either:
· Deleted
· Deleted or On-Hold
· On-Hold
· Expiring Soon
· Newly Deleted
· Available
· Registration
After defining the criteria, click “Search” to start the search process. PlexDomain will start searching the domain and will display results of search in a table format.
This option allows users to browse real-time list for newly-deleted domains. To start browsing, select
Domain->New->Newly Deleted Lists
The user
specifies the length of domain, whether it contains numbers or hyphens and
top-level domain. After specifying the criteria, click “Fetch” to start the
search.

This option allows users to crawl Yahoo or DMOZ directory, where it scans each category and check the domains that have expired. The job for directory crawling is run in background. It adds the expired domains to a file and notifies users. In order to schedule directory crawling job, select
Domain->New->Schedule to crawl directories
from the drop-down menu.

The user can
choose to schedule one-time or recurring jobs, which is scheduled at regular
intervals such as every night at
PlexDomain allows users to import list of domains from an external text file, which contains a domain name per line. In order to import domains, select
Domain->New->Domain Search
from the drop-down menu. It will show a search window similar to section 5.3.1. Then select
File->Import Domains
from the window’s drop-down menu and choose file that contains domain names.
PlexDomain allows users to import list of domains from an external text file, which contains a domain name per line. In order to import domains, select
Domain->New->Domain Search
from the drop-down menu. It will show a search window similar to section 5.3.1. Then select
Edit->Add Domain
from the window’s drop-down menu and type in the necessary information. See figure 6 for an example.

Once, users has selected the domains, he/she can filter those domains based on their popularity. In order to filter domain, user will need to open the domains or select “Domain Popularity/Filtering” tab if it’s already opened. In order to open previously stored domains, select
Domain->Open->Check Popularity & Filter Domains
from the drop-down menu.
Then select all the search engines and directories where the number of links for each domain will be searched. You may also select the minimum Alexa Ranking. For example, if you wish to choose a site from top 100,000, then choose “Not Exceeds” next to Alexa Ranking and type in 100000. It will ensure that only those domains who are listed on Alexa and whose ranking is below or equal to 100,000 will be selected. Similarly in order to choose popular domains, select “Exceeds” next to “Overall Popularlity” and type the minimum number of links that you think are appropriate. PlexDomain will then add the number of links on all selected search engines and will select domain only if the total number of links equal to or exceed the number entered by the user. You may also choose to select domains only if they are registered under Yahoo-Categories by checking “Yahoo-Directory.” PlexDomain allows users to filter all available domains or only selected domains. PlexDomain will search the domain in search engines only if they are not previously initialized. Once a particular search engine is initialized, it will continue to use that value. In order to reset popularity for a particular domain or all domains, choose “Reset” buttons.

PlexDomain allows users to specify or load from an external file, a list of keywords, top-level-domains with a set of prefix and suffix words and it generates all possible domain names. It then checks each of those domains against whois server and shows list of available domains. The user can either search for available domains in foreground, where PlexDomain searches and displays the available domains, but user cannot perform other tasks while PlexDomain is searching. Alternatively, user can schedule a background job, which searches for available domains and then saves those domains. The results can also be emailed to the user when done.
User can start power search in foreground by selecting
Domain->New->Power Search for Available Domains
from the drop down menu. It will start a wizard as follows






User can start power search in background by selecting
Domain->New->Schedule Power Search for Available Domains
from the drop down menu. It will start wizard similar to above figures, with few additional panels for scheduling information. The user can then open previously processed or scheduled domains by selecting
Domain->Open-> Power Search for Available Domains
From the drop down menu or by selecting
Domain->Open->Schedule Power Search for Available Domains
PlexDomain provides a “Whois” tab next to “Domain Popularity/Filtering” tab. Users can choose to find information about domains, which is stored in the registry database. However, this information is only available if the domain is “registered” or soon to expire. Once the domain is expired, the whois record is purged from the registry and will not be available. The user can search for whois-records for all domains or only selected domains. PlexDomain also parses whois-record and identifies important information such as contact, registration date, expiration date, etc. User can also export whois-records to an external XML file by selecting
File->Export Domains
from the window’s drop down menu.

PlexDomain allows users to run search or filtering jobs in foreground where the application blocks until the search is completed or in background, where they are run while the user can continue interact with the application. The background jobs are scheduled in three ways:
The main job-scheduling panel is launched by selecting
Domain->Open->Scheduled Jobs
from the drop-down menu.
It will show panel with list of jobs scheduled as shown in figure 9.

From the job-scheduling panel, user can perform following tasks:
The
job-scheduling-panel shows list of all scheduled jobs in a table format. The
table includes job name, start-date, whether it’s active, whether it’s been
completed and whether it’s recurring job. The user can filter these jobs by
choosing to show only jobs, which are scheduled for today, this week or this
month.
