Summary
Illinois Century Network (ICN)
education research legacy
ILLINOIS-CENTURY is the Illinois Century Network, the State of Illinois' statewide broadband network for public institutions, run by the Illinois Department of Innovation & Technology.
What it's used for
- Internet and intranet connectivity for K-12 school districts, higher-education campuses, public libraries, and state and local government sites across Illinois.
- Backbone transport over the state's open-access institutional fiber network, serving thousands of connected locations.
Notable
- Statewide research-and-education networks like ICN sit between a commercial ISP and a campus network: the addresses belong to the state network, but the users behind them are schools, libraries, and agencies.
- ICN was established by Illinois legislation in the late 1990s; ARIN's record for this AS number dates from 2001, so the low number does not indicate an early-internet allocation.
Interesting
- ICN participates in the national research-and-education community and provides its members access to Internet2, which is why Illinois K-12 traffic can end up on research-network paths.

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.
