education research legacy

An early, low-numbered allocation serving the University of Chicago, a private research university in Chicago, Illinois.

What it's used for

  • Campus, research, and administrative networking for the university and its affiliated laboratories.

Notable

  • An IP here is institutional (campus buildings, dorms, labs, research clusters), classified education rather than commercial hosting.

Interesting

  • A three-digit AS number reflects how early the university connected, when numbers were still handed out sequentially in small blocks.

Classification and threat

Education University, school or national research and education network.

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.
