Summary

Hellenic Cadastre

Greece · AI-generated

government cadastre gis business

KTIMATOLOGIO-AS is operated by Hellenic Cadastre.

What it's used for

  • The address space carries internal government infrastructure, identified by the netname HELLENIC-CADASTRE-GR and registrant HELLENIC CADASTRE.
  • The AS announces 256 IPv4 addresses across 1 prefix with 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic consists of internal systems for the Greek national land registry, supporting property record management, geodetic data, and digital transaction processing for government employees and authorized partners.

Notable

  • The RDAP registrant HELLENIC CADASTRE aligns directly with the AS holder KTIMATOLOGIO-AS HELLENIC CADASTRE.
  • The address inventory is a single /24 block, consistent with a dedicated corporate or government estate rather than a multi-site or consumer-facing network.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-12, 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: 453 networks and 1,848 prefixes, as published 2026-11-12. 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.
