Domain control and IP address Modification

We may need to re-plan the IP address. Can I change the IP address of the domain controller directly? If not, what should I do?
A: According to your description, I understand that you want to modify the IP address of the DC. You can directly modify the IP address, which is simpler than modifying the DC Name. After modifying the IP address on your behalf, you need to know the local DNS cache and then refresh the new IP address in the DNS, at the same time, you also need to manually or on DHCP modify the IP address of the DNS server (if the DNS service and DC are on the same server ), simply put, as long as the DNS record of your DNS server is up-to-date, the DNS point of the client is also up-to-date.
The following are the steps to modify the dc ip address.
1. log on to dc as an administrator
2. Run cmd.
3. Net stop netlogon
4. Ipconfig/flushdns
5. Net start netlogon
6. Ipconfig/registerdns
After a while, the new IP records of DC will be synchronized on all DNS servers. if these DC servers are dns servers, the following changes may need to be made. If they do not meet the following conditions, no changes are required.
1. If you have a dns proxy, You need to manually update the dns server records in the proxy region.
2. If other dns servers have configured forwarding to these DC servers, you need to modify the corresponding forwarder settings.
3. If the Domain Member (server or client) uses the manually set IP address, update these IP addresses separately. If DHCP is used, modify the corresponding DHCP settings.
In addition to the steps to change the IP address of the exchange Server, the following steps are required.
1. Modify the SMTP Virtual Server IP address settings of the exchange Server, use the new IP address, or change it to all unspecified addresses. Then restart the Simple Mail Transfer Protocol Service.
2. if you use the firewall to publish the address of the exchange server, you need to modify the corresponding policy. If you use the public address directly and record the mx record on the public network, you also need to modify the MX record through the dns modified by the ISP.
