[GRLUG] Comcast dual stack IPV6 spotted in Muskegon

[Eric Yagerlener]

FYI.  Comcast dual stack IPV6 is now live in Muskegon.  Maybe it's
live in GR as well.

I've tried it and it works, but they've already changed the IPV6
subnet prefix on me without warning.   Lease times are supposed to be
good for a week.

You'll need a DOCSIS 3.0 modem a router that supports both IPV6 and
DHCPV6-PD for it to work with Comcast. DD-WRT does not unless you
already have a version that supports IPV6 and hack in some packages
from OpenWRT to provide a dhcp client for IPV6.  DD-WRT does not
support ip6tables at all.

If your modem/router does support IPV6 and IPV6 is on by default you
may have already IPV6 and not know it.   Check your firewall
configuration, your default policy may be accept, not drop on IPV6!
