Checking quickly a #DNS zone: a new variant of check-soa
When you want to assert rapidly whether or not a DNS zone works fine, typical exhaustive tools like #Zonecheck may be too slow. There is room for a light-and-fast tool and many people used to rely on the check-soa program developed by Liu and Albitz and published with their famous book DNS and BIND. This original program no longer seems maintained and, the last time I tested it, did not support IPv6. So, I wrote one more variant of “my very own check-soa”.
