About this network

A Geneva provider selling connectivity and IT services, trading under the DFINET name.

What it's used for

• Business access and hosted services. Reverse DNS runs under dfinet.net, with one branch labelled for the medium — 254.5.143.94.ch.dsl.dfinet.net — and one sampled address answering as a customer's own mail.doors.ch.

Notable

• 52 observed BGP neighbours against 13,824 addresses. That is heavy interconnection for a network this size, and it is the clearest signal of what the business actually is.
• The netnames run CH-INNET-960807 from August 1996, then CH-INNET-20081209, CH-INNET-20120611 and CH-INNET-20191007 — over twenty-three years of assignments under one stem.
• One /23 is registered as AXONES to AXONE Service & Développement SA, a different company, with Cheops handling abuse for it.
• One IPv6 allocation, 2a00:1840::/32.

Interesting

• Three names sit on this network at once: INNET in every netname, DFINET in the AS handle and the reverse DNS, and Cheops Technology Switzerland as the registered holder. The netname is the oldest and least visible of the three, which is exactly why it is the one that never got updated.
• Geneva is a small city with an unusual concentration of international organisations, banks and research institutions, all of which buy connectivity locally. Fifty-two peers on fourteen thousand addresses is what serving that kind of customer looks like.
