Oh IPv6, Where Art Thou
- fulafel 11y agoShouln't everyone just be doing dual stack with real IPv6 + NATted IPv4 for the forseeable future? What's the point of T-Mobile trying to do CLAT/PLAT?
- daenney 11y ago"Just be doing dual stack" is not as easy as it sounds. The whole point of a carrier doing 464XLAT is that they (the carrier) can move to a IPv6 only network without breaking the internet experience for their customer until everyone else is also accessible over IPv6.
- p1mrx 11y agoWhen you have millions of customers, you start running into the limits of private IPv4 address space. Before deploying IPv6, T-Mobile was using 25.0.0.0/8 (assigned to the UK Ministry of Defence) for the internal side of their IPv4 NAT.
- api 11y agoBogarting unadvertised IPv4 space is common. A lot of people don't understand that it's not just public IP space that is in short supply in IPv4. IPv4 also has inadequate space to number large private networks in a non-conflicting manner. Causes all kinds of crazy headaches with VPNs and distributed networks too... try linking two sites that both use 10.0.0.0/16 sometime. It's hell.
- fulafel 11y agoT-Mobile already has many millions of real routable IPv4 addresses, so it's not like they would have to put everybody behind a single NAT.
- suprjami 11y agoJust turn off IPv4 and the problem will quickly solve itself. IPv6 day 6/6/16.

- kafeinnet 11y agoFun fact: labs.spotify.com has no IPv6.
