Good job! The fact that it said "contains 1 record" for you leads me to believe that it got an AXFR with only a SOA record or something. When I try to do it from a.authns.bitfolk.co.uk against your primary's IP I get a "NotAuth" response, which is interesting. I did not expect it to work because the address selection for source address would be an IP that you probably do not allow AXFR from¹, but I would have expected a Refused response in that case. Anyway I'd like to look into it more but not sure how best to proceed. Was this was done with the head of the main branch? I see it let you just do "--server 127.0.0.1" with no port. If you can still replicate it, maybe you could add a github issue? https://github.com/grifferz/ptrcheck-rs/issues Or email me privately about it if you'd rather not use github? Thanks, Andy ¹ So another option needed for source address? -- https://bitfolk.com/ -- No-nonsense VPS hosting
