Residential RIPE Cable/DSL/ISP
Summary
senseLAN
isp residential business switzerland
The AS handle SENSELAN-AS is held by senseLAN GmbH.
What it's used for
- The address space carries a mix of residential and business connectivity, evidenced by netnames like
CH-SENSELAN-20040423andCH-REGA-SENSE-20141125, alongside leased space for third parties such asrecretix systems AGandnet-track GmbH. - With 19,456 IPv4 addresses announced across 17 prefixes and 52 observed neighbours, the ratio suggests a regional access provider rather than a pure transit hub, consistent with its role as a local ISP in the Fribourg region.
Notable
- Registrants largely align with the announcer, including
senseLAN GmbHandsenseLAN Immobilien GmbH, though several prefixes are registered to distinct entities likeSaraxa GmbHandgutknecht-informatik.com GmbH. - The address inventory is fragmented into numerous /22 and /24 blocks, reflecting a granular allocation strategy typical of a growing regional operator managing diverse customer segments.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
