Running a FreeBSD server with two independent uplinks?
My latest deep dive covers how to mix a physical provider and a BGP tunnel to serve NAT'd, routed, and pure public jail traffic on a single bridge.
We break down Dual-FIB policy routing and show you how to use PF's rtable and reply-to […]
Part 3 of my hobby AS series is up: connecting my AS201379 to LocIX Düsseldorf via a dedicated FreeBSD edge router.
Covers route server peering, IPv6-in-IPv6 GIF tunnels, PF on a shared peering LAN, and iBGP back to the core […]

BGP FlowSpec lets you distribute traffic filtering rules across your entire network in seconds.
Most operators still aren’t using it.
Here’s how it works — and why that’s changing 👇
#BGP #FlowSpec #DDoS
FastNetMon + IP Infusion = automated DDoS defence on OcNOS.
Detect via sFlow/IPFIX. Mitigate via BGP Flow Spec or RTBH. Restore automatically when the attack stops.
Out-of-band. Disaggregated. Open standards end to end.

There is something better, and more secure, than #BGP: SCION. Will the world, or at least Europe, adopt it?

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.
#BGP is how you get there.
