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 three FreeBSD routers, 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

  • RPKI: Valid or Undefined. Valid IRR entries are the bare minimum.

Prefixes

I only do IPv6, as it's the modern internet standard.

  • 2a06:9801:1c::/48 IPv6 Only

Upstream

  • AS209533
  • AS20473
  • AS212895
  • AS34872
  • AS207841

Internet Exchange Points
