Summary
sasag Kabelkommunikation AG
cable residential regional switzerland
SASAG is the autonomous system for sasag Kabelkommunikation AG, a regional cable operator based in Schaffhausen.
What it's used for
- The address space carries residential cable and DSL traffic, evidenced by reverse DNS entries such as
dynamic-87-245-95-255.ptr.as35518.netandstatic-185-43-202-254.ptr.as35518.net. - The AS announces 40,960 IPv4 addresses across 7 prefixes and 1 IPv6 prefix, while maintaining only 7 observed neighbours; this high address-to-neighbour ratio indicates an access network serving local subscribers rather than a transit provider.
Notable
- All seven announced IPv4 prefixes are registered to
sasag Kabelkommunikation AGwith netnames likeCH-SASAG-20050823andCH-SASAG-19970528, confirming the registrant matches the announcer. - The inventory consists of two large /18 blocks and five smaller /21 and /22 blocks, reflecting a regional footprint with some historical address accumulation.

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: 448 networks and 1,851 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.
