Hosting RIPE
Summary
Adfinis
hosting business isp
The AS handle carries a domain name, and it belongs to a different brand than the handle's first word.
What it's used for
- A hosting and services company's network. Two IPv4 prefixes and one IPv6 prefix announced from Switzerland, two thousand three hundred and four addresses, across two observed BGP neighbours.
Notable
- The handle is the former brand followed by the current company's domain, so both names sit in one field with a space between them.
- One netname is a country code, the former brand and an allocation date. The other is the current brand joined to a service name that still carries the former brand's first two letters.
- That second netname is written in mixed case, where the first is capitals throughout.
- Both blocks list three contacts: a technical object, the company, and a hostmaster team whose name is hyphenated.
- The IPv6 announcement is a
/32, a full allocation beside two thousand IPv4 addresses. - Six addresses were queried for reverse DNS and none returned a name.
Interesting
- Putting a domain in a handle makes the record self-updating in the one way that matters: the domain resolves, so a reader can find the company even after the brand in the same field stopped being true. It is an accident that works.
- A rename leaves its traces in the order the fields get edited. The domain went first, the service name kept the old letters, and the older netname was never touched at all.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
