Before configuring a service point on a DNS/DHCP Server, you must
meet the following requirements:
- You have an active DNS Edge implementation with at least one site configured.
- You have a supported DNS/DHCP Server appliance running version 9.2.0 or greater.
- The DNS/DHCP Server is managed by Address Manager.
- The DNS/DHCP Server can successfully resolve and connect to the DNS Edge cloud endpoints. To ensure connectivity to the DNS Edge Cloud, you must configure DNS/DHCP Server with a nameserver that can resolve specific CNAME records and external endpoints. For more information, refer to Cloud access requirements in the DNS Edge Deployment Guide.
- Ensure you accurately configure the date and time on the DNS/DHCP
Server.Note: If there is an issue with the time synchronization and the time on the DNS/DHCP Server is offset by more than 5 minutes, the service point will not initialize.
- If Anycast is required, the DNS/DHCP Server must be associated with at least one DNS role.
- The DNS/DHCP Server is one of the following supported hardware
appliances:
- BlueCat Generation 4 Appliances BDDS-50 and higher
- BlueCat Generation 3 Appliances BDDS-60 and higher

xHA requirements:
- If you wish to enable a service point on an xHA pair, you must first configure both xHA nodes with the same DNS Edge URL, site ID, and service point IPv4 address before creating the pair. In the desired active node, you must add the service point IPv4 address as an additional IP address on the Service interface (eth0).
- If the DNS/DHCP Server is part of an existing xHA pair, you must first
break the pair, configure both xHA nodes with the same DNS Edge URL, site ID,
service point IPv4 address, and then recreate the pair with the service
point-enabled nodes. In the desired active node, you must add the service point
IPv4 address as an additional IP address on the Service interface
(eth0)Note: The same principle applies if you wish to disable the service point on an existing xHA pair; you must first break the pair before disabling the service point on each individual node.Note: Proxy Settings
If the proxy settings are configured for both of the cases above, the proxy host, port, and user must be identical between the 2 nodes.
