====== How to find the Authoritative Reverse DNS Server for a specific IP Address ======

===== The "dig" Way =====

If "digging" for a reverse name yields a cached response... e.g. the following command returns "p50939d12.dip0.t-ipconnect.de." as the reverse host name:
<sxh bash; gutter: false>
dig -x 80.147.157.18
</sxh>
<code>
; <<>> DiG 9.18.20 <<>> -x 80.147.157.18
;; global options: +cmd
;; Got answer:

;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1

;; OPT PSEUDOSECTION:

;; ANSWER SECTION:

</code>

Get the authoritative DNS server for the address with the following command:
<sxh bash; gutter: false>
dig -t SOA 18.157.147.80.in-addr.arpa
</sxh>
<code>
; <<>> DiG 9.18.20 <<>> -t SOA 18.157.147.80.in-addr.arpa
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 44130
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 1

;; QUESTION SECTION:

;; AUTHORITY SECTION:

</code>

Now you can direct dig to query the authoritative DNS server for the ip address:
<sxh bash; gutter: false>
dig @pns.dtag.de -x 80.147.157.18
</sxh>
<code>
; <<>> DiG 9.18.20 <<>> @pns.dtag.de -x 80.147.157.18
; (2 servers found)
;; global options: +cmd
;; Got answer:
