Looking for cheap v6 transit to balance my v4-heavy mix

Which tier-2 though, GeorgeNmp? Names or it didn't happen

I won't name names on a public forum because my NDA is real and my lawyer is expensive. What I will say is look at the European carriers with heavy government v6 mandates and excess 100G waves. They have ratio clauses in their upstream settlements that make negative v6 pricing rational at the margin. Not a scam, just inter-provider accounting.

Also what is RPKI I keep seeing it, is it hard to set up

Resource Public Key Infrastructure. Your RIR signs your prefix origination, you publish ROAs, routers validate with RPKI-RTR. Setup is a weekend project. Running without it in 2024 is malpractice.

iBGP, eBGP, don't care, just peer

Then you're just doing the "I know a guy" routine. Either post the ASN or admit it's forum lore. I've chased three of these "negative v6" leads and they all turned into "sign 3-year v4 commit first." The economics don't work at small scale.

Okay so RPKI is like SSL but for routing? That makes sense I guess. Is there a guide somewhere for someone running pfSense

Reykjavik_doc has a point, windows dhcpv6 is pain

Þe point was about edge architecture but yes, windows dhcpv6 is pain. Stateless autoconfig with RA guarded by SeND would be better but microsoft doesn't implement SeND because microsoft.

What distribution and what routing daemon? FRR with bird2 for v6 only or full unification?

Debian with FRR. Bird2 for a test POP but FRR won because our upstreams all use communities FRR documents better. No containers, just systemd units. Old school but it works.

Þe real issue is youre chasing ratio arbitrage instead of fixing your actual cost structure

My cost structure is fine, thanks. The v4 pricing is competitive. The problem is upstreams are starting to penalize v4-heavy blends in their 2025 rate cards. This isn't theoretical, I have the draft from two providers. I'm not chasing arbitrage, I'm avoiding a penalty.

Your 800 Mbps wont qualify

This is useful, thank you. Hetzner's 2G v4 bundle minimum explains why their negative pricing wasn't responding to my inquiry. Contabo's 12mo commit might work if the pricing holds. Anyone have experience with their BGP community support?

Have you tried restarting it?

Contabo communities are minimal. Prepend, no-export, blackhole. No granular traffic engineering. Their negative v6 is real but you get what you pay for. If you need community-based TE for your 70/30 split, look elsewhere.

Updated table with community counts:

Provider    | Communities | v6 TE | Notes
------------|-------------|-------|------
Contabo     | 3           | No    | Cheap, rigid
OVHcloud    | 12          | Yes   | prepend, selective announce
Vultr       | 8           | Yes   | regional withdraw
Hetzner     | 6           | Partial | no granular v6
fio, iperf, geekbench. results or gtfo.

Negative pricing is still accounting fiction. The provider pays you with money they got from overcharging on v4. Net net you're worse off. Better to negotiate straight v4 pricing than play ratio games.

This is real. I see it from Marseille to Frankfurt. The French IX members are pushing v6 ratios hard because ARCEP metrics. If your upstream has French peering, they're feeling pressure.

My suggestion: buy v6 from a regional French operator. They have the mandate, the excess capacity, and the desperation. Not negative pricing but €0.02/Mbps is achievable at your commit.

Post the penalty clause language? I collect these. The 2024-2025 shift in transit rate cards is fascinating and terrible. Also: check if the penalty is against ratio or absolute v6 commit. Some providers phrase it as "v6 must be minimum X% of blended commit" which is different from ratio and might change your math.
