Note: If the checker is configured to check domains by performing Whois checks (one of the 3 checking methods), it would be limited to as much as the domain registrar will allow as they have a limit on the number of times the domains can be checked. Without the Whois method enabled, you have practically unlimited checks, but at the cost of accuracy (i.e. some domains may show as available, when they are not)
