Summary

KDD d.d.

Slovenia · AI-generated

business slovenia small

The AS handle KDD is held by KDD d.d., a Slovenian telecommunications operator.

What it's used for

  • The space carries corporate and operational traffic, evidenced by the netname KDD-SI and registrant KDD RIPE team.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small-scale access or internal corporate network rather than a transit provider.

Notable

  • The registrant KDD RIPE team and netname KDD-SI align directly with the announcer KDD d.d., confirming consistent ownership.
  • The address inventory consists of a single /24 block (193.0.244.0/24) and a /47 IPv6 prefix, representing a compact and self-contained estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, 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 1,783 prefixes, as published 2026-10-17. 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.
