Domain check is the process of verification of availability of a domain name before an attempt for buying it. When a domain name is registered, it will be leased to its new owner for a specific period of time (minimum 1 year). After the domain lease expires, it will be available for registering again.
ETYN's Domain Check is a free web-based online tool that verifies availability of a domain name. Currently only .COM, .NET, .ORG, .MOBI, .BIZ and .INFO domains can be verified.
