My autonomous System AS201379 is now connected to an Internet Exchange Point (IXP): LocIX in Düsseldorf.
It's already showing up in the global routing table and traffic already starts flowing through the direct links with my peers 🙂 […]

Oh, hey, #IANA assigned a new block of ASNs to #AFRINIC. A good sign that the #Internet #connectivity in #Africa is growing! Keep up the good work! Details here....

BGP tells your network where to send traffic.
But it doesn't tell you what's actually happening inside the control plane.
That's what BMP (BGP Monitoring Protocol) is for.

On Feb 20, Cloudflare lost 1,100+ BYOIP prefixes from BGP for 6 hours. No attack, just one buggy API query that ran before anyone could stop it.
Large-scale routing automation is fragile. Independent visibility and control over your own network isn't a nice-to-have.

I built a live map of the Internet's BGP routing. It features an anomalies dashboard that acts as a global networking wall of shame. Just pray your own AS number doesn't pop up on it! 🗺️🚨

Most of us only notice the Internet when it breaks. But under the hood, thousands of routers are constantly negotiating paths to keep things running.
I wanted to visualize this chaos, so I built a live map of the Border Gateway Protocol (BGP). I even included a "BGP Anomalies" dashboard, which […]

Back in October of 1995, some time after I founded Infinity AccessNET, I filed and turned up autonomous system number 5767.
AS 5767's ASname actually is INFINITY.

There is this saying that when you grow up, you are leftist in your youth and over age, you grow more conservative.
Over time, we have received numerous peering request of smaller ASN that want to peer = Accept and just configure their session.
Nowadays I get annoyed when someone doesn't reply […]
Ever wonder what happens when you outgrow a single BGP router? I wrote a deep dive on building a multi-homed, two-PoP distributed network using FreeBSD, FRR, and iBGP.
Includes the stateless PF rules you need to survive asymmetric routing!

#BGP #IPv6 #FreeBSD
I just published a new guide on evolving a single BGP router into a multi-homed, two-PoP network using FreeBSD, FRR, and PF.
- Native peering on Vultr + 3 GRE transits
- Tying it together with iBGP
- Why stateful firewalls break asymmetric transit (and how to fix it)
All for ~€18/mo.
