ipnodes(4) OSS Shell and Utilities Reference Manual
NAME
ipnodes - Defines the hosts using IPv6 network addresses
DESCRIPTION
The Guardian IPNODES file is the IPv6-equivalent of the IPv4 /etc/hosts file. It contains IP
addresses and host names, where the IP addresses can be either in IPv4 or IPv6 format.
Guardian DEFINEs determine whether a name resolution service is searched first, or whether the
local databases (the IPNODES and hosts files) are searched first. If the DEFINEs
=TCPIPˆNODEˆFILE, $SYSTEM.ZTCPIP.IPNODES and =TCPIPˆHOSTˆFILE,
$SYSTEM.ZTCPIP.HOSTS are in effect, the Guardian copies of the local files are searched first.
No /etc directory link is used for IPNODES. NonStop TCP/IPv6 does not require an OSS
/etc/ipnodes file.
Each entry in the IPNODES file has the format:
node_address st ack_name
where
node_address Specifies a text string version of the address. This has one of the following
forms:
IPv4 Dotted decimal format as ddd.ddd.ddd.ddd, for example:
172.17.201.43
IPv6 Hexadecimal string format as x:x:x:x:x:x:x:x, for example:
1080:0:0:0:8:800:200C:417A
Compressed hexadecimal string format that omits zero values,
for example:
1080:::8:800:200C:417A
In mixed form as x:x:x:x :x:x:d.d.d.d, for example:
::FFFF:13.1.68.3
as a mapped value, or
::13.1;68.3
as a compatible value.
stack_name Is an arbitrary character string that identifies the TCP/IP stack or host for the
corresponding host address.
NOTES
The maximum length of an IPv6 address as a text string is defined as INET6_ADDRSTRLEN in
the header file in6.h.
