Summary

SHAPE (Supreme Headquarters Allied Powers Europe)

Belgium · AI-generated

government military nato belgium

SHAPE-AS is operated by The North Atlantic Treaty Organization, specifically supporting Supreme Headquarters Allied Powers Europe (SHAPE).

What it's used for

  • The address space carries NATO military infrastructure, evidenced by netnames BE-NATO-20140115, NCIA, SHAPE, and SHAPE-GATEWAY.
  • The AS announces 1792 IPv4 addresses across 4 prefixes with only 1 observed neighbour, indicating a small, isolated internal network rather than a transit or access provider.

Notable

  • All registrants consistently identify as NCIA-Contact; The North Atlantic Treaty Organization; Abuse Contact, aligning perfectly with the announcer.
  • The address inventory is compact and finely subdivided into four distinct blocks, reflecting site-by-site segmentation for a specific military command 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.
