AS201379
Since January 2026, I have been running my own Autonomous System, AS201379. Here is the most important information:
I run this AS with a setup consisting of FreeBSD routers (a core plus edges at LocIX, FogIXP, EVIX, and Vultr), utilizing FRR (FRRouting) to handle multi-homed BGP sessions with several upstreams. In fact, this website (and my adjacent blog) are hosted directly within the address space of this very AS!

Peering Policy & Requirements
If you want to peer with me, you're welcome! My peering policy is generally open, but I do have a few expectations to ensure a smooth and secure connection:
- Technical contact information must be kept up-to-date.
- Strict route filtering must be enforced to prevent accidental route leaks.
- We should collaborate in troubleshooting peering issues, actively mitigating DDoS attacks, and resolving security incidents.
- Please do not abuse the peering link by pointing default routes or unnecessarily resetting next-hops.
How to Request Peering
If you're interested in peering, just send an email with the following details about your network to get started:
- A short introduction to your network (just so I know who I'm connecting with!)
- Desired peering points (e.g., IPv6-in-IPv4 tunnel, GRE, or LocIX)
- Your Autonomous System Number (ASN)
- Your AS-SET (if you have one)
- The recommended maximum prefix limit I should configure for you
- Your contact details
You can send your peering requests directly to peering@hofstede.it.
Routing Security
- Prefixes I accept must be RPKI: Valid or Undefined. Valid IRR entries are the bare minimum.
-
My prefix is covered by a ROA (origin AS201379, max length /48) and by
route6andas-setobjects in the RIPE database.
Prefixes
I only do IPv6, as it's the modern internet standard.
