View Full Version : [ubuntu] Does Ubuntu Desktop have dual IPv4 and IPv6 stack?
August 5th, 2008, 02:39 AM
ISPs over my way are starting to provide IPv6 (e.g. http://ipv6.internode.on.net/) on their networks. Windows Vista has a dual IPv4/IPv6 stack.
Just wondering if Ubuntu has a similar way of doing things?

The short answer is yes. To see that ipv6 is enable in a terminal tyoe:
you should see something like this:
::1 localhost ip6-localhost ip6-loopback
and in a terminal:
eth0 Link encap:Ethernet HWaddr 00:16:17:9c:84:b5
inet addr:192.168.1.102 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::216:17ff:fe9c:84b5/64 Scope:Link

Note the inet6 addr:

Say I didn't want to use DHCP and want to give a Ubuntu Desktop box a "fixed" IP address of 192.168.0.11 under IPv4 could you please advise how I can give the Ubuntu Desktop box also an IPv6 "fixed" IP address as well?
Also, if I wanted to use just one stack is there a way of disabling the other? Please advise.
Finally, I gather that IPv6 has additional security provisions (e.g. encryption?) is this enabled by default?
