Summary
Trenka Informatik AG
hosting business switzerland
TRENKA is operated by Trenka Informatik AG, a Swiss IT services and hosting provider.
What it's used for
- The address space carries hosting and IT infrastructure services, evidenced by netnames like
CH-TRENKAandTRENKA-NET, and reverse DNS entries pointing totrenka.ch,trenka.net, andkanban.ch. - With 3328 IPv4 addresses announced across 6 prefixes and 54 observed neighbours, the ratio suggests a business or hosting network rather than a large-scale residential access provider or pure transit carrier.
Notable
- All registrants in the RDAP data align with the announcer, listing
Trenka Informatik AGorTrenka Informatik NOCfor every prefix. - The address inventory is finely subdivided into six distinct IPv4 prefixes, including a mix of /22, /23, and /24 blocks, indicating site-by-site or service-specific segmentation within the corporate estate.

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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
