Summary
The Cambridge Incubator
hosting business enterprise
Seven upstreams behind a name that describes a landlord.
What it's used for
- A company network. Five IPv4 blocks announced from the United States, no IPv6, and seven observed BGP neighbours.
Notable
- Four blocks carry the netname
CAMBRI-51and the fifth carriesCAMBINC-1, two different abbreviations of the same holder. - The AS handle matches the odd one out,
CAMBINC-1, rather than the netname on most of the space. - The five blocks come from three unrelated parents, so they were acquired separately.
- Fifteen addresses were queried for reverse DNS and none returned a name.
Interesting
- Seven neighbours is the number to notice. That is far more connectivity than five small blocks need for their own traffic, and it is the shape of a network carrying other people's, which is what an incubator's network is for.
- The two netname abbreviations were coined by different people at different times. One truncates the first word and adds a counter that counts nothing here; the other joins both words. Neither is derivable from the other, so matching this holder by netname finds at most four blocks in five.
- Nothing answers in reverse across fifteen addresses. A network with this much transit and no public names is either serving outbound traffic only or leaving its reverse zone unpopulated on purpose.
- Address space collected from three separate parents usually means three separate arrangements, each surviving whatever ended the last one.

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 1,771 prefixes, as published 2026-10-15. 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.
