Yea I heared about it before. Aren't we out of IP's or something already? Dunno the technical details, since I'm not that much in to pc software/hardware/etc as I used to do years ago ... But my fiance told me something like that in the past. Cool, but mindblowing... The internet running out of space sounds like finding the end of the universe
IPv6 is hella old news lol, like circa-Windows Vista. Anyways, a couple fun facts are that Comcast offers 6to4 tunneling IPv6 support ((you need an account to see links)) & it has built-in filtering/security removing the need for subnet masking.
