2019 Domain Controller NIC configuration

Question

Hi,

Its been a while since I've done new DCs. Is there any changes I need to put in place for a DC NIC?
Like registerdns in DNS client settings or remove certain NIC protocols that aren't needed?

Answer 1

I'd leave the protocols stock, then generally speaking add the domain controllers own static ip address plus the loopback (127.0.0.1) listed for DNS

Answer 2

What about disabling ipv6 on the nics on all the new 2019 DCs? we don't use ipv6
we typically disabled ipv6 on our existing 2012r2 DCs.

Answer 3

You should be fine to leave it checked on connection properties as long as there isn't a rouge (router?) that happens to have an enabled IPv6 DHCP server on the network.
