Summary

Cambridge Associates

United States of America · AI-generated

business corporate finance

CAMBRI-AS1 is operated by Cambridge Associates, a global investment firm.

What it's used for

  • The address space carries corporate infrastructure, evidenced by registrants CAMBRIDGE ASSOCIATES, LLC and netnames like CAMBRIDG313-209 and CAMBRIDG95-153.
  • The AS announces 1024 IPv4 addresses across 4 prefixes with 4 observed neighbours, indicating a small internal corporate estate rather than a transit or access network.

Notable

  • Registrants largely align with the announcer, including CAMBRIDGE ASSOCIATES, LLC and Cambridge Associates, though one prefix is registered to AT&T Global Network Services Nederland B.V.
  • The inventory consists of four distinct /24 blocks, including legacy ranges from 12.0.0.0/8 and 194.69.0.0/16, suggesting a mix of historical and current corporate allocations.

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 1,773 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.
