Domains and DNS

Typically, domains are defined in a DNS. For each domain, the DNS lists all node IP addresses assigned to each network with which the domain is associated.

With DNS, you can manage domains in a single set of corporate DNS servers. Alternatively, you can set up separate DNS servers for different networks that use the same domain. Or, you can use a combination of these two techniques. In any case, you need to ensure that your networking environment and DNS configuration allow client requests to be routed to the correct HCP network.

If DNS is in use at your site, you can take advantage of DNS configuration options to further enhance the security of the HCP networks. However, HCP does not require the use of DNS. Without DNS, you can still define multiple domains in HCP and associate them with networks. In this case, to enable client requests to be routed to an HCP network, users would use the hosts file on each client computer to map the node IP addresses assigned to the network to the fully qualified domain name (FQDN) of the domain associated with the network.

From the Networks page in the HCP System Management Console, you can display the stub zone definition that you need to include in the DNS for each combination of domain and network. For more information on this, see Viewing the DNS zone definition for a network domain.
