Summary

NASA Deep Space Network

United States of America · AI-generated

government space research nasa

NASADSN-AS is operated by NASA Deep Space Network (DSN).

What it's used for

  • The address space carries infrastructure for the Madrid Communications Complex, as indicated by the netname MDSCC-NET and registrant Madrid Communications Complex.
  • The AS announces 1024 IPv4 addresses within a single prefix (192.243.16.0/22) and has 0 IPv6 prefixes. With only 1 observed neighbour, this indicates a dedicated, isolated network segment rather than a transit or access provider.

Notable

  • The registrant Madrid Communications Complex aligns with the specific facility associated with the announced prefix, while the AS holder is the broader NASA DSN organization.
  • The address inventory consists of a single /22 block, representing a finely subdivided internal corporate estate for a specific ground station site.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-02, 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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
