IPv8 / BGP8 / CF
by Jamie Thain 05 May '26

05 May '26

Hi All, My name is Jamie Thain I'm the creator of IPv8. It's not a hoax. I joined this list because, as part of IPv8, I am creating a BGPv8. Inside BGPv8, two new protocols CF (Cost Factor), weigh cost factors along the routes to produce a better metric. It's a hybrid of EIRGP mixed with BGP to create better engineering results. I also as part of CF created Sun Tzu which is the protocol that watches CF and gives you a CF score of reliability. Do I trust my partnership with you? Now, beyond an on-slaught of IPv8 is stupid, IPv6 solves every problem, etc, etc. That's not my discussion point. My point isn't "should I even propose IPv8" my point is what would be the best result for operators? I believe that since IPv8 solves the duopoly problem, it will replace IPv4. So the things to know, IPV8 is NOT a 64 bit addressing system. It is a 32 bit routing system with a 32 bit addressing system. A Routing Number = ASNs plus others. 8.8.8.8 would become 15169.8.8.8.8 https://www.ietf.org/archive/id/draft-thain-ipv8-02.html <https://l.shortlink.es/l/3ae384c1b8e2eb92749595407c5cf9b87ea3372a?u=12457652> So each ASN in the world will have 3 Billion available addresses. There is a specially reserved group of internal ASN 127.x.x.x so each corp, org, has 16 Million areas of 3 Billion addresses, to replace 10.x.x.x and 100.64.x.x.x I'd appreciate your thoughts on it Jamie

4IXP DOA ?

Looking to see if anyone on the list knows anything about the 4IXP “virtual IXP” - https://www.4ixp.com/ ? Specifically - is it a dead project ? I reached out to a few email addresses for them and never got any replies. My next step is to look at https://bgp.exchange/. I don’t think they are the same ? (but their sites and services look very similar at a quick glance) Thanks for any info.

Trying to resolve a reachability issue: from AS2769 164.119.119.1 164.119.0.0/16 to AS32575 202.65.16.4 202.65.16.0/20 Traceroute shows path dying at AS3257 GTT 213.254.231.86 213.254.192.0/18. Same result testing from two different transit origins 98.23.127.145 (Uniti / Windstream AS7029) or 74.51.211.245 (UPN / Segra AS15164). Last hop prior to reaching GTT is AS1299 Telia / Twelve99 62.115.138.75 from both origins. This problem has persisted for more than a couple weeks. Please PM if you can lend assistance. Thank you, Chad D

Digital Realty- Non Renewal
by Robert DeVita 25 Apr '26

25 Apr '26

Is anyone else having problems not getting renewed in Digital Realty Facilities. We had the same customer not get renewed in Frankfurth last year and now in Ashburn this week. They are clearing out suites to lease to hyperscale customers. I totally understand the business decision on their side, but I think this will become more common place in the future.
