I'm looking for help running tests against DNS servers. I want to list all the subdomains for a specific domain. So I try to use the dig command with axfr and it fails every time. dig @ns.SOA.com somedomain.com axfr Am I doing it wrong or are modern dns servers hardened and no longer accept this query? Is there a better way to do this? For example, so I build a dns server and try to replicate records to query? Would the axfr command be accepted if it came from a dns server? If so, what is the 'check' that I would be passing, so I could spoof it. Next DNS question along the same lines, I want to do reverse dns lookups. It also seems that all the DNS servers I tried don't accept this, which is the proper behavior after hardening. However we all know, not EVERYBODY does the proper settings and there is always somebody out there with some default settings. Are the queries wrong or am I just not finding a server that allows reverse dns? Anyone know of some servers that accept reverse dns? Anyone know a good resource to find these one in a million dns servers?
