Dear Mat,

Chris is right in the fact that It’s now been probably around years since Swisscom introduced dual-stack (means native v4 AND v6 addressing) to RES end-customers. We didn’t do so because we would like to shine, but just because infrastructure at that moment both forced AND let us do. 6rd was a quick and dirty way how to “v6-enable” subscribers rapidly, but clearly bandwidth-growth killed this approach even more rapidly 😉.  So, in our organization there is now engineers, who know the term 6rd only from theory – if ever 😉.

When it comes to public or private IPv4 addressing let me say: We try to give out public addresses whenever we can. But Swisscom too can’t address all the subscribers publicly with the amount of addresses we got years back. This results in the fact that lowest-end (or even VOIP only purpose) products would be CGNATed on IPv4.

Hope this helps getting you the picture.

Kind Regards

Egon

Subject: [swinog] Residential FTTH IPv6

Be aware: This is an external email.



Hi all,

This came up recently when I was talking with some colleagues about residential connections... You know, regular stuff people discuss over a beer or two... We all know Init7 is recognized as The Provider for power users and no one argues with that. But also everyone knows we have mainstream ones kinda-supporting IPv6. Swisscom gives public IPv4 and IPv6 via 6rd tunnel. Similar with Sunrise, but sometimes you end up on CG-NAT. Salt is only CG-NAT, at least according to the anecdotal proofs.

Power users wouldn't be power if they did not try stuff. So I took my Sunrise FTTH over native fiber (EWZ in my case, not Swisscom BBCS) and it turns out I get public IPv4 from DHCP (expected) as well as IPv6 /56 prefix via DHCPv6 (not expected at all). The last one is extremely surprising - the status quo was that you can get IPv6 with Sunrise via 6rd, but DHCPv6 is a novelty. Or is it not?

What is the state in 2024 ? Who does IPv6 ? Who does it natively ?

I am surprised there is no single google result about Sunrise doing DHCPv6 so I wonder what we don't know about other ISPs.

Cheers and have a nice day,
Mat
