Summary

Telprom

Slovenia · AI-generated

business it slovenia

BTC-AS is operated by Telprom Informacijske tehnologije d.o.o.

What it's used for

  • The address space carries corporate infrastructure, evidenced by reverse DNS entries such as n58.net.telprom.si and n174h128net.telprom.si.
  • The AS announces 2560 IPv4 addresses across 2 prefixes with 3 observed neighbours, indicating a small-scale business network rather than a transit or large access provider.
  • Traffic originates from Telprom's IT services and electronic store operations in Ljubljana, representing office workers and business endpoints.

Notable

  • Registrants for both announced prefixes (ORG-TItd1-RIPE and TELPROM) align with the AS holder, TELPROM Informacijske tehnologije d.o.o.
  • The inventory consists of two distinct IPv4 blocks: 178.216.56.0/21 and 194.0.174.0/23.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-10, 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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
