Summary

Halcom d.o.o.

Slovenia · AI-generated

business software digital-certificate b2b

HALCOM-AS is operated by Halcom d.o.o.

What it's used for

  • The address space carries corporate infrastructure, evidenced by reverse DNS entries ca.halcom.com and onep.halcom.ba and netnames SI-HALCOMDD-20151225 and SI-HALCOM.
  • The AS announces 512 IPv4 addresses across 2 prefixes with 2 observed neighbours, indicating a small, self-contained business network rather than a transit or access provider.
  • Traffic consists of web and API endpoints for Halcom's B2B software and digital certificate services, including qualified digital certificate issuance in Bosnia and Herzegovina.

Notable

  • Registrants for both prefixes are consistent with the announcer, listing Halcom RIPE team and Halcom d.o.o..
  • Halcom d.o.o. is a B2B service provider specializing in programming and software solutions, established in 1992, with operations in both Slovenia and Bosnia and Herzegovina.
  • The inventory consists of two /24 blocks, 185.74.90.0/24 and 193.219.106.0/24, with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, 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: 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.
