Unclassified RIPE
Summary
European Space Agency (OPSNET)
government research legacy
ESA-MOSNET is held by the European Space Agency. The single announced block, 195.74.160.0/19, is registered as ESA-OPSNET — the agency's operational network — and is administered from Germany, where ESA's European Space Operations Centre (ESOC) in Darmstadt runs spacecraft operations.
What it's used for
- Connectivity for ESA's operational and intranet estate: the ground-segment and mission-operations infrastructure, and the agency's internal systems across its establishments.
- About 8,000 addresses, announced as one contiguous /19 with a single observed BGP neighbour.
Notable
- The block publishes no public reverse DNS at all — nothing resolves across the range. That is normal for an operational agency network that is not meant to serve public-facing content; the address space exists to reach ESA systems, not to host them for the internet.
- ESA is an intergovernmental organisation of European member states, so this is government/public-sector address space even though it belongs to no single country. The registry country reflects where the network is administered, not ownership.
Interesting
- ESA's public web presence lives elsewhere; this AS is the quiet side of the agency, the network behind mission control rather than the one behind the press releases.

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.
