Network Port Configurations

To ensure the optimal performance and seamless operation of the DDI solution, the following network port configurations are required:

DNS (Domain Name System)

TCP and UDP Port 53: Must be open for DNS query and response traffic. DNS uses this port for both TCP and UDP protocols to handle standard query and response action, as well as zone transfers (TCP).

DHCP (Dynamic Host Configuration Protocol)

UDP Port 67 (Primary DHCP): Must be open for receiving DHCP discovery requests from DHCP clients. This is the standard port on which the DHCP server listens for and responds to DHCP discovery messages and other requests from clients.
TCP Port 647 (DHCP Failover): Must be open to enable communication between primary and secondary DHCP servers in a failover configuration. This port is used for synchronization of DHCP lease information and other configuration data to ensure continuity and consistency of DHCP services in case one of the servers becomes unavailable.

These port configurations are essential to allow the DDI system to communicate effectively within your network infrastructure. Ensure that any firewalls or network security systems are configured to permit traffic on these ports for the DDI solution's components.
