To change the Static IP of a DC:

1.Log on locally to the domain controller whose IP address you want to change.

2.Click Start, point to Administrative Tools, click Server Manager, and then click View Network Connections.

3.In the Network Connections dialog box, right-click the appropriate connection, and then click Properties.

4.In the Connection Properties dialog box, double-click Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6).

5.In IP address, type the new address.

6.In Subnet mask, type the new subnet mask if it has changed.

7.In Default gateway, type the new default gateway.

8.In Preferred DNS server, type the address of the Domain Name System (DNS) server that this computer contacts if it has changed.

9.In Alternate DNS server, type the address of the DNS server that this computer contacts if the preferred server is unavailable.

10.If this domain controller uses WINS servers, click Advanced, and then, in the Advanced TCP/IP Settings dialog box, click the WINS tab.

11.If an address in the list is no longer appropriate, click the address, and then click Edit.

12.In the TCP/IP WINS Server dialog box, type the new address, and then click OK.

13.Repeat steps 11 and 12 for all addresses that have to be changed, and then click OK twice to close the TCP/IP WINS Server dialog box and the Advanced TCP/IP Settings dialog box.

14.Click OK to close the Internet Protocol (TCP/IP) Properties dialog box.

Besides of changing the IP-address on the network interface as described above.
Also verify that you use the correct default gateway.
If possible then make sure you have access to the server via another NIC on a different IP-address or access to the console.
Also verify that you have the local Administrator account/password so in case the server can not reach the domain anymore you are still able to logon. For the DC you need the domain Administrator account or an account with the same privileges.
After the IP change.
For all servers:
Execute a few "ping <computer>" commands to other servers/workstations to make sure the connection is working fine.
If there are firewalls in your network also make sure that the firewall allows the connection from and to the new IP-address.

Execute from a command prompt (Run as Administrator): ipconfig /registerdns
 to update the DNS records of the server.
Wait for AD replication and check that the A and PTR records are updated with the new IP-address in DNS.

For DC's: Check DNS if the IP-address is updated for all AD related SRV records.
If the DC is running DNS then it might be that member servers or workstations do have the IP-address configured in their DNS settings. If this is the case then check that there will be at least one DNS IP-address to another DNS server available after the change. On these computers update the old IP-address with the new IP-address directly after the change.

For DHCP servers: restart the DHCP server service after the IP-address change

Also keep in mind that because of the DNS cache mechanism on the client it can take a while before the IP-address is updated.
The amount of time depends on the DNS records Time To Live (TTL).
If necessary you can temporary lower this TTL value in DNS.
