ZoneCheck performs several tests on your DNS zone to ensure that it is correctly configured, and can be safely delegated.

Note The Zone name must be either a Domain name, in-addr.arpa zone, or ip6.arpa zone name. See help for examples

Warning IPv4 RIR Pools are completely depleted! There are already some European and Asian Service Providors only issueing IPv6 Addresses!
This will only become more the normal, so zones with no IPv6 DNS Servers will soon be issued a FATAL ERROR Result
