Reliance Jio Fiber Static IPV6 IP

[cadddr]

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.

ssh connection drop after few minutes

Does the connection drop if connected over ipv6 also?

No, it's their nat being aggressive.

Yeah I mean then there's nothing to investigate per say. It's an issue with all providers using CGNat, who have a large client base

Use Cloudflare Teams. Its free and uses Wireguard. But getting the required info. (Private key/ public key/ gateway) to run on Wireguard requires additional steps.

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.

@Notorious can you help me with the script to update the ivp6 address for the subdomain on Cloudflare, can you tell what is the downtime i.e. how much time it take to update the DNS record. What strategy are you using to check for the change in ipv6 address
