Residential RIPE
Summary
Cheops Technology Switzerland (DFINET)
isp business legacy
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 ownmail.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-960807from August 1996, thenCH-INNET-20081209,CH-INNET-20120611andCH-INNET-20191007— over twenty-three years of assignments under one stem. - One
/23is registered asAXONESto 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:
INNETin every netname,DFINETin 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.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 432 networks and 1,768 prefixes, as published 2026-10-12. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
