The domain names resolved by DNS are divided into zones, where each zone is defined by a set of related hostnames. A corporate domain, for example, is associated with a zone.
Each domain you define in HCP is a subdomain of a higher-level domain. In the DNS, you need an HCP domain definition for each combination of network and domain you define in HCP. The IP addresses for each HCP domain in the DNS make up a zone within the zone for the applicable higher-level domain.
For example, suppose that you configure HCP to define two domains, hcpma.example.com and hcp-ca.example.com. Suppose also that you configure HCP to define three user-defined networks, net1, net2, and net3,and you configure these three networks to associate net1 and net2 with domain hcp-ma.example.com and associate net3 with domain hcpca.example.com. In this case, you need to add three zones to the DNS, one for each of these domain and network combinations:
Domain name: hcp-ma.example.com
Node IP addresses defined for network net1
Domain name: hcp-ma.example.com
Node IP addresses defined for network net2
Domain name: hcp-ca.example.com
Node IP addresses defined for nodes in network net3
