Summary

K-sys

Switzerland · AI-generated

isp residential switzerland ftth

The AS handle KSYS is operated by K-sys SA.

What it's used for

  • The address space carries fixed broadband subscriber traffic, evidenced by the reverse DNS record 0-101-31-185.ftth.cust.kwaoo.net which identifies the connection type as FTTH (Fiber to the Home) and the customer segment.
  • The network announces 1024 IPv4 addresses and 1 IPv6 prefix, with a single observed neighbour, indicating a small-scale access provider rather than a transit carrier.
  • Traffic from this AS consists of residential internet users accessing the public internet via fiber optic connections.

Notable

  • The registrant for the announced prefix 185.31.100.0/22 is listed as K-NET NOC; K-sys SA; KNET ABUSE, which aligns with the AS holder K-sys SA.
  • The inventory consists of a single contiguous IPv4 block and one IPv6 prefix, representing a compact and unified address estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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 1,773 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.
