Domain Checker is a simple, but powerful whois lookup tool for users that require a domain availability analyzer. The software supports the most common TLDs, and users are free to add new ones. Anyone interested in releasing new websites will benefit from this utility, as it allows one to check for domain name availability. The ability to batch process multiple entries makes it a worthwhile tool, more-so when several options are being considered for the future site. The application features an efficiency-geared GUI that allows one to quickly generate simple or advanced scans.
