“Today we’re going to learn how to use routable IPv6 addresses,
some iptables rules to keep our experimentation from leaking out
into the world, and about implementing DNS in IPv6.“You can perform all these tests on any two Linux PCs on your
LAN without getting in the way of your normal IPv4 activities. Just
remember to undo everything that you don’t want to be permanent
when you’re finished. Save time and hassle by having SSH set up on
all your PCs; then you can park yourself comfortably in one place
and run most of these tests over SSH sessions and never get up,
except at healthy intervals to prevent embolisms and joint
seizures.”
