How to Check if Domain Controller IP Has Changed with PowerShell?

Honestly, why not just deploy new DCs with the new IPs and demote the old ones? Changing network details after promoting a DC can lead to issues. It's better to avoid complications, in my opinion.

Are you asking if the IP itself changed or if the DNS records have been updated? It’s a bit confusing. If you changed the IPs, you should already know that, right? For confirming IP changes, you can use some basic commands like `ipconfig`, `Get-NetIPAddress`, or `Get-NetIPConfiguration`. These tools have been around forever and should still work. Can you clarify your request?

It sounds like you're trying to ensure that all your Domain Controllers acknowledge the new IP address. A good first step is to check the DNS since Active Directory relies on it to retrieve the IPs of DCs. You might want to write a PowerShell script that resolves the DC IPs through DNS. Also, consider flushing the local DNS resolver cache on each DC and the DNS server to help ensure everything is up to date.
