What it's used for

  • The network announces 1024 IPv4 addresses and 1 IPv6 prefix, with 2 observed neighbours, indicating a small-scale enterprise or business network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate operations for an IT consulting and auditing firm based in Dübendorf, Switzerland.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
