Summary
University of Illinois Chicago (UIC)
education university research legacy
UIC-AS is the campus network of the University of Illinois Chicago, a large public research university and the state's largest university in the Chicago area. Registered to UIC's technology organisation on West Taylor Street.
What it's used for
- Campus, research, medical-centre and administrative networking for UIC, including its health-sciences colleges and hospital.
- Announces two full legacy
/16s —128.248.0.0/16and131.193.0.0/16— giving it roughly 131,000 IPv4 addresses, plus IPv6.
Notable
- Two Class-B-era
/16s is a distinctly institutional footprint: universities that connected early were routinely given whole /16s, and many still hold them. A modern network of UIC's size would never be issued that much space today. - UIC is also a research network participant, so a share of the space carries research and high-performance-computing traffic rather than ordinary campus users.
Interesting
- Chicago has a dense cluster of low-numbered academic ASNs; UIC's sits close to other mid-1990s university registrations in the same range.

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 2026-10-19, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 2026-10-20. 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.
