If you change the IP address of a domain controller that is a Domain Name System (DNS) server, you must update the IP address in the delegation for the DNS server in the DNS zone for the parent domain.I'm having mysterious issue that confused me for such a long time till now, I've got one DC which acted as DNS and DHCP as well.However it is successfully giving out IP address to all IP enabled device and machine but when updating the DNS entry, only the Windows machine (workstations and server) gets their IP registered in the DNS server, therefore i cannot ping and access the other Linux machine apart from using IP address only.Even when registering DNS on the client, nothing is added on the DNS servers.
We have 2 DNS servers and randomly when we move a machine to a different VLAN, the DNS entry never registers the new IP.
I believe this is based on the assumption that they are clients, and do not need to be reachable by name, or servers already listed in static DNS with a static DHCP lease.
DNS servers provide domain name resolution for network resources.
Perform a packet capture (wireshark) on the client or the server (easier on the client, less packets) to verify this hypothesis.
If the client is not sending its hostname to the dhcp server, it has no way to update the dns zone.
