Lightning-fast availability checks
The ISproxy interface offers the most efficient way to check domain name validity and availability. It reduces overhead by using a telnet based protocol that allows multiple checks to be made in parallel. The interface can be used most effectively by reusing existing sessions as much as possible. This will lower the overhead on session creation and authentication.
