It is no surprise, though, that the IPv4 address still appears in Samba DNS (can be seen when running 'samba_dnsupdate --verbose'). I am aware of the documentation for changing an AD DC's IP address, but I could not find documentation regarding removing an IP address.

I want to do this because IPv4 is a legacy protocol. I do not need IPv4, it is old, and I do not want IPv4 in my network if I don't need it.
