Summary
Lambton College
education business canada
The AS handle LAMBTON-COLLEGE is held by Lambton College of Applied Arts and Technology.
What it's used for
- The address space carries institutional infrastructure, evidenced by netnames
LAMBTON3andLAMBTON4registered to the college. - The inventory consists of 3 IPv4 prefixes totaling 1024 addresses, with 0 IPv6 prefixes announced.
- With only 2 observed neighbours, the low neighbour count relative to the address block suggests a small, self-contained network typical of a single-site educational institution rather than a transit provider.
Notable
- Registrants for the two /24 prefixes (
LAMBTON3,LAMBTON4) align with the announcer, Lambton College of Applied Arts and Technology. - The largest prefix, 192.139.190.0/23, is registered to "Various Registries (Maintained by ARIN)" with netname
NET192, which differs from the college's direct registrations. - The address inventory is small and fragmented into three distinct blocks, consistent with an internal corporate or institutional estate.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, 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 1,781 prefixes, as published 2026-10-16. 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.
