Contabo IPv6 madness

Okay, so I have a little gripe with Contabo, I have a VPS with their EU HUB and for some reason, IPv6 there seems flawed.

I added prefix::1/64 to vtnet0 and this address is pingable. However when I add an IP alias prefix::2/128 and use this source address in ping, I get no replies.

Contabo says they assign a /64 per-VPS..

PF is disabled during the test. ndp -na shows their gateway address in the table with an Expire of a few seconds..

netstat -rn6 | grep default shows the default gateway pointing to them, all seems good yet somehow a mystery..

Anyone face similar issues like this with them ?

    @goetz@ipv6.social he did thanks, it's in some ways similar to a Netcup issue I had, They use a switched network, and the same issue had pop up on FreeBSD and OpenBSD.

      @madamada I have toyed around with multiple IPv6 addresses in the past and am pretty sure it worked that time. ๐Ÿ˜… (but i ain't exactly an expert)
      Try checking your firewall and routing config one last time and if you don't spot anything amiss there, then you could try asking their support.

        @namedbird@noc.social Thanks, I've done those checks multiple times just to be sure, PF was disabled the entire time to rule out it's not a firewall issue..netstat -rn6 doesn't indicate anything off..and ping/curl using the main IP on the Interface works ..

        I'll be escalating this to their support for sure..
