Every Domain Controller (DC) implements two main domain services. One is the Key Distribution Center (KDC) and the other is the Active Directory(AD).
The KDC is essentially a network service that supplies session tickets and temporary session keys to users and computers within a domain, and it uses the Domain Controller’s Active Directory service as an accounts database. The IP Address that needs to be entered in the Domain Controller (DC) Host Name/IP Address field is the address of the KDC.
This can be done by using this command in your ADs command prompt:
Here, replace DOMAIN_NAME with the complete domain name of your Domain Controller.
