IPv6 - stateless or stateful?

IPv6 - stateless or stateful?

My Asus RT-N66U router offers a choice of stateless or stateful auto configuration for  IPv6, but doesn't explain what that means.

 

Which should I choose, and what difference would it make? The default appears to be stateless.

Re: IPv6 - stateless or stateful?

isnt DHCPv6 the option? http://tools.ietf.org/html/rfc4862  all about IPv6 Stateless Address Autoconfiguration..  Great read Smiley Happy

 

http://en.wikipedia.org/wiki/IPv6 also works..

Re: IPv6 - stateless or stateful?

Wow, you pointed me to an RFC! I haven't seen one of those in years! It made my head spin. In fact, IPv6 makes my head spin in general.

 

OBTW, I was in the 1978 Arpanet directory. It was a paper book of everyone on the net who had an email address. It was about 1/2 inch thick.

 

DHCPv6 is no longer the option at least in the Merlin firmware. I haven't checked the Asus firmware.

Looks like you got it.. 2601:: is the Comcast PD space..  So you have a PD on your LAN..  You should be good to go..

 

And yes the RFC was a fun to read..

Re: IPv6 - stateless or stateful?

I've got that same router (Asus RT-N66U) with Merlin firmware installed and also have been wondering whether to use stateless or stateful for my home network. There will be 5 or 6 devices served by my router at any given time, some ipv6 capable, some older ones that only do ipv4.

 

I've reset the router with both stateless and stateful selected, and I don't notice any connectivity or performance issues with either option.

 

Alamo_Bob, why did you settle on a Stateful configuration? How do I determine which setting will be best for my home network? Does it even matter?

 

p.s. Thanks for the links to the docs, but I'm affraid they are beyond my comprehension of the technicalities of IPv6.

I didn't settle on Stateful. I just clicked Stateful so the pool options would become visible for the illustration.

 

I still don't know the answer. The technical docs were beyone me, too. I'm staying with Stateless because it seems to work.

Thanks Alamo_Bob,

 

I'm sticking with stateless too for now, same reason: it works, and I don't understand the difference or why I would switch to stateful for a small home network on Comcast IPv6.

Windows (and most likely other OS) clients use stateless IPv6 DHCP by default. There would be no reason to select stateful unless (if I am reading that article correctly) you intended to have more control over the IPv6 addresses of the clients.
