compare / diff 2 DNS servers. useful when migrating dns servers
lets say you're migrating from Dreamhost DNS to Cloudflare DNS, and you wonder if you forgot something, run:
php dns_diff.php ignore_columns=TTL dns1=ns1.dreamhost.com dns2=andy.ns.cloudflare.com domain=loltek.net
and you should get something like:
DNS records differ for loltek.net MX dns1=ns1.dreamhost.com dns2=andy.ns.cloudflare.com
dig @"ns1.dreamhost.com" "loltek.net" MX +cl +ttlid +nomultiline
dig @"andy.ns.cloudflare.com" "loltek.net" MX +cl +ttlid +nomultiline
