If you are changing your DC IP make sure you run ipconfig /flushdns, ipconfig /regsiterdns, and dcdiag /fix.
Don't forget about all your routers, printers, firewalls, and other network devices. Anything that has a static IP will need to be manually updated.

So is mean I no need touch any configuration in DNS server I just run a command do will fo fix every things?
With your DCs if you run those commands everything should update properly
A few questions to get things clear.
Do you have multiple sites?
Do you use vlans?
Who manages your routers/firewalls?
How many nodes (workstations/printers/etc /etc..) are we talking about?
If I understand correct your migrating from 125.1.xxx.xxx to 192.168.xxx.xxx, correct?
With these questions answered we can give you better answers.
DC and DNS are one thing, you need to make changes to all your ip owning devices (e.g. printers, etc)
What would help is use DNS as much as possible so you only need to make address changes only in one place.

I know ,I need to make changer in firewall,how about routers?
Hello, can you be more specific as to which routers you are talking about? Most routers and switches will have a static ip so yes you will have to log into them and manually change the IP.
You may need to make changes in your firewall/routers if they're filtering, NATing, or otherwise manipulating traffic based on IP address.
I'm guessing most of your clients are DHCP so they'll take care of themselves. Regardless, you'll want to plan on doing this over a weekend, and nothing much else getting done until things settle down.
