Summary

Ministerio de Defensa

Spain · AI-generated

government defense military

MDE-AS is operated by Ministerio de Defensa, the Spanish Ministry of Defence.

What it's used for

  • The address space carries government and military infrastructure, evidenced by the netname MDE-NETS and reverse DNS entries pointing to mde.es.
  • The AS announces 512 IPv4 addresses within a single prefix (193.33.2.0/23) and maintains only 1 observed neighbour, indicating a small, isolated internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal communications, command and control systems, and administrative services for the Spanish armed forces.

Notable

  • The registrant Ministerio de Defensa aligns directly with the AS holder and the mde.es domain in reverse DNS.
  • The address inventory is compact, consisting of a single /23 block, which is typical for a specific government department's internal estate rather than a large-scale ISP.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-28, 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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
