Summary
NATO SACLANT Undersea Research Centre
government military research legacy
AS5502 is registered to the NATO SACLANT Undersea Research Centre in La Spezia, Italy. The organisation is today NATO's Centre for Maritime Research and Experimentation (CMRE), part of the NATO Science and Technology Organisation, and the registry name simply preserves an older title.
What it's used for
- Networking for a NATO scientific research and experimentation facility: staff, laboratories and the systems behind its maritime research programmes.
- A small, single-prefix footprint of 512 addresses, consistent with one institutional site rather than a service provider.
Notable
- This is a government/military address holder. The organisation is an international military-alliance body, not a company, and its space is not sold or resold.
- The registry entry is a stub with a sponsoring LIR, which is how end-user (non-provider) NATO and government assignments typically appear in the RIPE database.
Interesting
- The centre has been at La Spezia since 1959 and has been renamed several times: the SACLANT Anti-Submarine Warfare Centre, then SACLANT Undersea Research Centre, then the NATO Undersea Research Centre, and since 2012 the Centre for Maritime Research and Experimentation. The AS name froze at one of those older stages.

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.
