I have now subscribed to jio fiber, and latency is much better(<180ms) to most of europe(both v4/v6 routes).
Regarding the /64 prefix subnet i am pretty sure jio doesn't share that with other customers, since you can enable dhcpv6 stateful allocation and the address pool is fixed:
The problems:
- ssh connection drop after few minutes(need to investigate).
- block cloudflare warp, i would need a dedicated VPN for wireguard.
I also think /64 isn't shared. I tried adding a couple of IP addresses on my machine using
ip addr add and was able to hit them from outside. didn't observe any clashes, but could have been luck.Anyway even if they give 64 bits, they still have other 64, still giving them 32 extra bits when compared to ipv4. If most ISPs (other than Jio) can give a public ipv4 (unshared) with DHCP, should be easy to give a /64 to the user. This is quite good.
