Sorry, but am not quite sure if this is a network or an Internet question.... So I apologize ahead of time if it needs to be moved....
Anyway, I just bought a gently used cable modem from a friend to use with Comcast. Only thing is the modem isn't officially rated for IPv6 (at least, not now... not sure if the mfr will have a firmware upgrade later), but anyway, when the Internet moves to IPv6, what will happen to older hardware that is only rated for IPv4? Is legacy IPv4 still going to be in place at least for a year or two while everyone upgrades to IPv6-certified hardware/software?
(I didn't pay much for this modem--only $25, but would like to at least get some use out of it---maybe at least a years worth to make the effort of obtaining it worthwhile. That and, for what it's worth, my router IS IPv6 capable--although I don't know if that will help the modem any if it isn't).
