Summary

Actual I.T.

Slovenia · AI-generated

business it-services slovenia

ALTERNA-AS is operated by Actual I.T. d.d.

What it's used for

  • The address space carries corporate IT services infrastructure, evidenced by the netname ORG-ULD1-RIPE and registrant ACTUAL I.T. d.d.
  • The AS announces 256 IPv4 addresses across 1 prefix with 2 observed neighbours, indicating a small-scale business network rather than a transit or large access provider
  • Traffic consists of office workers and IT service endpoints for a company operating in the computer-related services industry

Notable

  • Registrants agree with the announcer, with ACTUAL I.T. d.d. listed as the registrant for the announced prefix
  • Telekom Slovenije, d.d. agreed to acquire Actual I.T. d.d. from DBA Group S.p.A. for €20.6 million on March 28, 2022

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.
