Summary
Carleton University
education university research ottawa
CARLETON-U is the autonomous system for Carleton University, a public research institution in Ottawa.
What it's used for
- The address space carries university infrastructure, with reverse DNS entries pointing to academic and administrative hosts such as
es-net.earthsci.carleton.caanddhcp-95-254.ls-research.carleton.ca. - The AS announces 65,536 IPv4 addresses across 7 prefixes and 1 IPv6 prefix, while maintaining only 3 observed neighbours, a ratio indicative of an access network serving on-campus users rather than a transit provider.
Notable
- All registrants for the announced prefixes are listed as Carleton University with the netname
CARLETON1, fully aligning with the AS holder. - The inventory consists of a single contiguous IPv4 block (134.117.0.0/17) that has been subdivided into seven smaller prefixes, reflecting internal site-by-site segmentation of the university's estate.

Interconnection

Internet exchanges
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 2026-10-16, 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 1,783 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.
