The /etc/inet/ipnodes file stores both IPv4 and IPv6 addresses. This file serves as a local database that associates the names of hosts with their IPv4 and IPv6 addresses. You should not store host names and their addresses in static files, such as /etc/inet/ipnodes. However, for testing purposes, store IPv6 addresses in a file in the same way that IPv4 addresses are stored in /etc/inet/hosts. The ipnodes file uses the same format convention as the hosts file. See Network Databases for a description of the hosts file. See ipnodes(4) man page for a description of the ipnodes file.
IPv6–aware utilities use the new /etc/inet/ipnodes database. The existing /etc/hosts database, which contains only IPv4 addresses, remains the same to facilitate existing applications. If the ipnodes database does not exist, IPv6–aware utilities use the existing hosts database.
If you need to add addresses, you must add IPv4 addresses to both the hosts and ipnodes files. You add only IPv6 addresses to the ipnodes file.

You must group host name addresses by the host name, as shown in the previous example.
