I want to love IPv6 but it's unfortunately still basically impossible to get good proper IPv6 in the first place.
At home I'm stuck with fairly broken 6rd that can't be hardware accelerated by my router and the MTU is like 1200 which is like 20% bandwidth overhead just for headers on the packets.
On the server side, OVH does have IPv6 but it's not routed, so the host have to pretend to have all the IPv6 addresses and the OVH routers will only accept like 8 of them in use before its NDP table is full, so assigning an IPv6 to every Docker container fails miserably.
IPv6's main problem is ISPs are so invested in NAT and IPv4 infrastructure they just won't support IPv6. Microsoft, Google and Apple need to team together and start requiring functional IPv6 to create user demand, because otherwise most users don't know about CGNAT and don't care. Everything needs to complain about bad IPv6 connectivity so users complain to ISPs and pressure them into fixing it.
We were offered a /32(?) for like 1000$/yr… sounds like a good deal tbh
IPv6 or IPv4?
A /3 of IPv4 for that price is impossible, that'd be 10% of the entire IPv4 space. A /29 (32-3) would be more reasonable but 1k for a block of 8 IPs would be a massive ripoff.
Doesn't make sense for IPv6 either, as that'd be exactly the global unicast range (2::/3), but makes sense they'd give you like a huge block in there, maybe a /32 as that's what they assign to an ISP. As an end user you usually get a /48.
Phone keyboard ate the 2.. it’s a /32 block ipv6
