That's one reason I suggest trying the HE Tunnelbroker "certification". It takes you a fairly structured learning curve, so while you still have to find information, it at least gives you some guidance on the topic to look for. It's a while since I reached sage level, but IIRC it starts at the basics (addressing syntax etc) and works up - each stage is an incremental step from the one before.

If you don't know then they probably don't ! The ones that do tend to shout about it.
Are you with BT (as your headers suggest) ? If so then IIRC I don't think they do - although their routers are supposed to support it.

Ah, just spotted this linked to elsewhere :

Can't help too much there - my "router" is a Debian Wheezy Xen guest running Shorewall (and Shorewall6).


A few links, though to be honest I've struggled finding what I consider a "good" tutorial & reference :

http://www.ipv6now.com.au/primers/IPv6PrefixPrimer.pdf
If you understand IPv4 prefixes then you'll follow this, but it's key information

http://www.tutorialspoint.com/ipv6/

A few random jottings that come to mind ...

IPv6 doesn't use broadcast protocols like arp, it uses a multicast based neighbour discovery process.
Where you might have used "arp" in the past, now use "ip neigh show" - or more specifically "ip [4|6] neigh show"

Many familiar things support IPv6, either as a separate program (eg ping6 vs ping) or with a "-6" option (eg "telnet -6 ...").

"ip" is the default tools for seeing and manipulating Ip addresses, routes etc - just add the -6 option.

If you need a completely manually configured interface (like as my mail server), then you can avoid auto config by adding a stanza like this to /etc/network/interfaces (this is for Debian and derivatives) :
iface eth0 inet6 static
  address <addr>
  netmask 64
  gateway <addr>
  pre-up echo 0 > /proc/sys/net/ipv6/conf/eth0/autoconf


Hope that's some help. I'm afraid it's hard to say "I learned it this way" because I've been dipping my toe in for a few years now, and quite honestly can't recall most of the information sources I've used. I can certainly understand you finding it daunting !
