Summary

Valsil d.o.o.

Croatia · AI-generated

business cisco croatia

HR-VALSIL is operated by Valsil d.o.o.

What it's used for

  • The space carries corporate infrastructure, evidenced by the netname HR-VALSIL-KT-20160105 and registrant Valsil d.o.o.
  • The AS announces 1024 IPv4 addresses and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small-scale internal or business network rather than a transit or access provider
  • Traffic from this AS consists of internal corporate communications and services for Valsil d.o.o., a Croatian company

Notable

  • The registrant Valsil d.o.o. matches the AS holder, confirming consistent ownership
  • The address inventory consists of a single /22 block (185.133.132.0/22) and one /35 IPv6 prefix (2a05:70c0::/35), representing a compact and self-contained allocation

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: 447 networks and 1,849 prefixes, as published 2026-10-30. 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.
