What exactly are the meanings of the following settings when manually configuring network interfaces on CentOS (I'm trying to configure an IPv6 only host)?
I can guess what some of them mean by their name but I don't know what all of them mean (and some of my guesses could be wrong); is there any official documentation for these configuration options, I can't find any?
IPV6INIT=yes # I assume this just enables IPv6 networking on this interface? IPV6_AUTOCONF=no # Does this disable SLAAC? IPV6_AUTOTUNNEL=no # ? IPV6_FAILURE_FATAL=no # Something to do with IPv6 not working not being an issue? IPV6_DEFROUTE=yes # ? IPV6_PEERDNS=yes # Does this mean we use the default gateway for DNS queries? IPV6_PEERROUTES=yes # Same as above? IPV6ADDR=1::2/64 # This is obviously the IPv6 address and subnet mask IPV6_DEFAULTGW=1::1 # This is obviously the default gateway
Also for IPv4 the settings
DNS2 exist, do the equivilent ettings
