Host Names and IPv6 Addresses
The following section provides additional information on how addressing
works on HP-UX 11i v2 IPv6 bundled as part of TOUR 2.0.
Creating the /etc/hosts File
It is generally recommended to add IPv6 addresses (known as AAAA
records) to a DNS Name Server only when the following conditions are
true:
• The IPv6 address is assigned to the interface on the node
• The address is configured on the interface
• The interface is on a link which connects to the IPv6 infrastructure
HP recommends beginning with IPv6 addresses and host names in the
/etc/hosts file on a development network; then adding IPv6 addresses
and hosts to a Domain Name Service when moving IPv6 to a production
backbone network.
This subsection describes how to edit the /etc/hosts file to add an IPv6
address and host name for the network interface you are configuring.
NOTE If using the name service DNS over IPv6, add the IP address and host
name to the appropriate databases on the name server system. Refer to
BIND v9.2.0 (or later) documentation on http://www.docs.hp.com for
more information on DNS over IPv6.
The /etc/hosts file associates IP host addresses with mnemonic host
names and alias names. It contains the names of other nodes in the
network with which your system can communicate.
An example /etc/hosts file ships with HP-UX 11i v2 bundled as part of
TOUR 2.0.
Example Host Name Entry
The example below shows how a system with the name, host3, might be
referenced in the /etc/hosts file:
