Not sure IPv6 will fix this. Technically, yes it does. But major providers only assigning a /64 to a home user (and charging hefty fees for "buisness use" /48)

Not sure IPv6 will fix this. Technically, yes it does. But major providers only assigning a /64 to a home user (and charging hefty fees for "buisness use" /48) already leads to IPv6 NAT or segmenting the /64 further - which shoulnt be done.
- lazide 3y agoMost seem to have stopped and are handing out /48’s in my experience. Do you know any not doing that still?
- littlecranky67 3y agoI'm with one of the biggest german internet providers (o2 Telefonia) and they are not even providing any IPv6 at all (at least not in all regions, and without calling support to enable this feature individually).
- lazide 3y agoThanks for the correction! Hopefully they get their act together soon.
- mike_hock 3y agoWhy would anyone need /64 if not to segment it further.
- littlecranky67 3y agoWell ask the IETF, the RFCs say that sub-segmenting a /64 shouldn't be done. Yet people do, and the result is - well - here be dragons depending on the implementations.
- zamadatix 3y agoSo nobody ever again needs to think "what size end user subnet is in use". It's /64, it's always /64. It doesn't matter if you're embedding MAC addresses, using random assignment, using multiple assignments, have 1 device, have 1 trillion devices. It's a /64.
- mike_hock 3y agoOk, then why waste a /64 on that? A /96 should be enough, or even a /112.
- TheHappyOddish 3y agoThat might be a 'your area of the world' issue. Every 'major provider' I've dealt with hands out /48s.
