What it's used for

COOPERSUKacross all prefixes. - The network announces 65,024 IPv4 addresses across 7 prefixes with only 2 observed neighbours, a ratio that indicates an internal corporate estate rather than a transit or access provider.

- The address inventory is finely subdivided into seven prefixes ranging from a /17 down to a /23, all within the 164.143.0.0/16 block, reflecting site-by-site segmentation typical of a large enterprise.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
