I enter my username/password on the modem so I'm pretty sure it is processing the packets and such. There is no mention of anything IPv4 or v6. I'd suspect it is v4 only, since it works it has to support v4. lol So, old modem may have to be bricked at some point. I do have a newer gray modem that came with the DSL kit. I stopped using it because it got so warm. The old black box one runs cool and it has more vent holes. I may have to check and see if the gray one supports v6 but it is fairly old too. It's at least 10 years old. My router also makes no mention of IPv4 or v6. I suspect it is in the same boat as the modem, it doesn't support it and doesn't have the option to either. I did go to the Linksys website and look for a firmware upgrade, nothing available, not even a old one. I did some searching for routers with ipv6 support. I'm not finding a lot. Is this something I need to worry about yet? I mean, is there a lot of IPv6 equipment even available right now? Thanks to all for the info. Both had good info that helped. Water isn't quite as muddy as it was. Dale :-) :-)
