This should be easy, right ?
What are you trying to achieve?
You need to be on the same network as the next hop (ie router), otherwise you can’t communicate with it. That means that either your ISP or your VPN provider, will have to have the same prefix.
In a matter of “asking” for an IPv6 address, ie using DHCPv6, I don’t think most ISPs do this. Hopefully your ISP just hands you a GUA prefix through SLAAC, meaning you’ll do a Router Discovery broadcast when enabling IPv6 on your host interface, you’ll get a Router Advertisement back, and from that you get the prefix. With the prefix in hand you generate the last 64bits either randomly or through EUI64 (if privacy isn’t your thing).
When I say hopefully, it’s because at least one of my possible ISPs insists on DHCPv6 with a ridiculously short lease time. Or at least that’s what the customer rep said before I ran away.
Use a free Hurricane Electric ipv6 tunnel. They’ve been the go-to “my ISP doesn’t handle ipv6” solution for years.
Thanks that looks like the best I can hope for in terms of disposable, geographically, low cost ipv6 adresses. They give whole /48 so I imagine they expect you to keep using them. Hopefully there is also a way to release the addresses when you’re done with them.
I was hoping I could route any single ipv6 address to my location but looks like ipv6 doesn’t have as much address portability as I’d hoped!
