United States · AI-generated

education university research legacy

UNIVCENTFLA is the campus network of the University of Central Florida in Orlando, one of the largest universities in the United States by enrolment.

What it's used for

  • Campus, research and administrative networking across UCF's Orlando campuses.
  • The address space is almost entirely the legacy 132.170.0.0/16, registered to the University of Central Florida with ARIN in 1989 and de-aggregated into a few dozen more-specific announcements.

Notable

  • Institutional address space, not eyeball or hosting: it carries staff, student, lab and residence-hall networks rather than commercial subscribers.
  • The 1989 network registration and 1997 ASN registration place UCF among the early US university connections, arriving through the regional research networks of that era.

Interesting

  • The de-aggregation into many /24s and /22s inside a single /16 is a common shape for older campuses, which grew by carving departmental blocks out of one large legacy allocation rather than requesting new space.

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: 454 networks and 1,847 prefixes, as published 2026-11-11. 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.
