How to disable IPv6 in Soalris

How to disable IPv6 in Soalris

APPLIES TO :  Disable IPv6 in Solaris, Solaris Operating System - Version 8 6/00 U1 to 10 8/11 U10 [Release 8.0 to 10.0]

ISSUE :  Currently no ISO images available with IPS repositories for Oracle Solaris Studio, nor with patches for Oracle Solaris Studio.

GOAL :  This document describes what files to remove or edit to disable IP Version 6 on Solaris[TM] 8,9,10 on systems that only require IPv4 (IPv6 configuration is no longer needed)

SOLUTION :  This document describes what files to remove or edit to disable IP Version 6 on Solaris[TM] 8,9,10 on systems that only require IPv4 (IPv6 configuration is no longer needed)

Prerequisites :   It is not recommended to disable IPv6 on Solaris 11.

               1. Make a backup of the IPv6 NDP daemon's configuration file, (if it exists),
by using;
                      # cp /etc/inet/ndpd.conf /etc/inet/ndpd.conf.`date +%Y%m%d`

               2. Remove any lines from the IPv6 NDP Daemon's configuration file. Then
add these 2 lines;
                      StatefulAddrConf false
                      StatelessAddrConf false
                              These lines will prevent remote and automatic IPv6 address assignments.

               3. Stop and restart the NDP Daemon;
                      svcadm restart ndp

               4. Delete any IPv6 interfaces, for example using "net0/v6";
                      ipadm show-addr
                      ipadm delete-addr net0/v6
                      ipadm show-addr

               5. Disable the following services;
                      # svcadm disable svc:/network/routing/legacy-routing:ipv6
                      # svcadm disable svc:/network/dhcp/server:ipv6
                      # svcadm disable svc:/network/dhcp/relay:ipv6

               6. Reboot to verify IPv6 remains off
