Summary
Tulsa Community College
education legacy
TULSA-COMMUNITY-COLLEGE is the campus network of Tulsa Community College, a public two-year college in Tulsa, Oklahoma with roughly 14,000 students spread across four main campuses and additional community sites. Addresses here are institutional, not commercial.
What it's used for
Campus networking. RIS sees five IPv4 prefixes totalling 1,280 addresses, no IPv6, and two observed neighbours. Two neighbours is an end site with a pair of upstreams for resilience, which for a public college usually means a commercial ISP alongside a state or regional research-and-education network. The space carries the ordinary institutional mix: administrative systems, campus wireless and lab machines, the student portal and library resources. It is small enough that most student-facing services are almost certainly hosted elsewhere, in a cloud or a statewide shared system, with only the campus edge numbered here.
Notable
- All five prefixes are registered in ARIN to Tulsa Community College itself, under network names abbreviating the college's former identity as Tulsa Junior College. Self-registered space announced by its own registrant is the cleanest possible confirmation that the AS holder is the real operator, with nothing leased in from a third party.
- The four contiguous
/24s plus one older, unrelated block are the fingerprint of an institution that acquired address space in two eras and never renumbered. - No reverse DNS was returned on the ten addresses sampled. That is a sample of the space, not a finding about it, and nothing is inferred from the absence.

Interconnection
Peering at a glance
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 2026-10-18, 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 1,784 prefixes, as published 2026-10-19. 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.
