“Twenty years ago, two computer scientists at the University of Southern California created a key component essential to the modern Internet.” For all the talk about vulnerabilities, low functionality, et cetera, I love that we have robust, proven and — to be frank — old protocols on the net. The biggest change to phone numbers over the years has been area codes, then letters-as-numbers — something that has still to properly pervade here in the UK — and then that’s about it.

DNS has evolved in a similar way. Sure, we get new area codes (TLDs, SLDs) once in a while, and some of the backend on the trunks gets updated (new record types), but on the face of it, DNS is still the same bloody useful system it was when it was created 20 years ago. That rocks.
