This plugin gives administrators the ability to easily get a list of domains on their cPanel/WHM server that do not resolve to the correct IP. This is very helpful when doing server to server transfers, or auditing a server to remove old accounts. You can run this script and easily see a list of domains that are pointing to the old server or customers who are no longer hosted on their server.
Installation:
# cd /home
# rm -f latest-accountdnscheck
