As I'm (slowly, begrudgingly) learning about IPv6 I can't help but agree. Astounding that backwards compatibility was abandoned in favor of ... Being able to hand out a /64 or /48 to anyone with a pulse? No residential customer needs that many addresses, yet I can call my ISP today and block that off for eternity. To what end?
IPv6 should just have been a superset and 0..1.xxx.yyy.zzz.ttt should have been the legacy IPv4 space. I really don't get the point of all the bizarre block assignments, hexadecimal fetish, and general "why is this seemingly purposefully such a pain in the ass" feeling I get whenever I look at it.
- coolspot 5y agoIPv6 has like 4B * 65k ~= 260T (260,000,000,000,000) unique /48 addresses (subnets). Should be enough for every human on earth for sure.
- kaliszad 5y agoIt is something like one /48 for each second square meter of land on Earth or something in that ballpark. It definitely can be exhausted, but that is only because we more or less use the last 64 bit for grouping hosts, autoconfiguration etc. which doesn't have to be the case everywhere (e.g. container hosts, where giving each container or even a container host a /80 can be more than enough).
