How to get all NS records currently set on all domains on my cPanel server

Introduction

Sometimes you want this information when a large number of domains are being moved and you want to know which need manual updates and which do not. You can loop through all the domains or all users and domains to get that information.

Procedure

The simple dig method:

cat /etc/{local,remote}domains | while read dom ; do echo "NS records for $dom"; dig +short NS $dom; echo "-------"; done

This will produce output like the following through all domains:

NS records for siteone.com
ns1.siteone.com.
ns2.siteone.com.
-------
NS records for sitetwo.com
-------
NS records for tasteofasialaverne.com
ns1.someremote.com.
ns2.someremote.com.
-------

The second is to use a cPanel uapi that will provide much more information:

awk -F ": " '{print "domain="$1 " --user="$2}' /etc/userdomains|grep -v nobody | while read x; do uapi DNS has_local_authority $x; done

The API used is documented at: Return whether local DNS server is authoritative

Please note the above one-liners are provided as-is and as examples. cPanel doesn't write custom scripts or code. Anything further would need to be adjusted by a qualified system administrator obtained.
