16.6. Setting DNS Entries for Multi-Homed Servers

Some server machines may support multiple network interface cards (NICs). Multi-homed machines typically have multiple IPs, all assigned to the same hostname. This works fine in FreeIPA most of the time because it listens on all available interfaces, except localhost. For a server to be available through any NIC, edit the DNS zone file and add entries for each IP address. For example:
ipaserver  IN A  192.168.1.100
ipaserver  IN A  192.168.1.101
ipaserver  IN A  192.168.1.102
