Ever wondered what it’s like to bring physical IP transit directly to your home over #MPLS? I pulled it off — twice — in India.

#BGP, #IXP, fibre runs, barter deals, and plenty of Layer 8 chaos. Blog post up now👇

Think native IPv6 in Docker is rocket science? 🚀 It’s not.

Set up routed IPv6 with Docker Compose—no NAT66, no bridging, just pure Layer 3 connectivity via routing.

Helped fix a network mess at a non-profit where “certified experts” left behind broken #IPv6, triple #NAT, and the wrong hardware. Might not have been incompetence—might’ve been intentional.

Yet another post about #CGNAT - because the #internet still hasn’t learnt. It’s 2025, and we’re still patching #IPv4 with CGNAT instead of embracing #routing with #IPv6.

Please read and circulate this explainer from @telegeography.bsky.social that debunks the recent sensationalist headlines stemming from the filing of a Chinese patent for a subsea cable cutter (cut and hold grapnel):

Nice to see that my IPv6 Architecture guide has been helpful enough to inspire ISPs in the USA to adopt BCOP-690—especially with a static /48 prefix delegation for residential customers to boot!

A couple of years into the telecom/NetEng industry and I'm deploying networks the way I envisioned them, across the globe, from my eBGP-speciality for SP networks on a budget, to intricate and scalable OOB networks to hybrid enterprise networks with intelligent BUM forwarding.

I have officially shut down #AS149794’s operations in #BLR. This includes terminating services with #ExtremeIX and my transit provider, deactivating the #BGP session.

I’m exploring opportunities to secure physical IP transit from alternative ISPs in the future.

Looks like my (free) 10Gbps IP Transit+transport in #BLR, is coming to an end, soon-ish, it's been a fun journey, but all things (free) must come to an end eventually!

Question for #IXP operators - do you establish #iBGP adjacency between two route servers? Why/Why not?

Yeah I said TCAM in my post but later I referred to it as RAM because nobody knows what TCAM is. Arista's large table solution (algomatch???) uses RAM. You are right most routers *sold* today support tables above 1M but if you look around an Equinix colo you will find that they dont replace stuff.
