Summary

Sheridan College

Canada · AI-generated

education university legacy

SHERIDAN-NET belongs to the Sheridan College Institute of Technology and Advanced Learning, a public college in Oakville, Ontario with campuses across the Greater Toronto Area. The ASN is a 1995 ARIN allocation.

What it's used for

  • The college's campus network, announcing the legacy 142.55.0.0/16 block that covers its Oakville, Brampton, and Mississauga sites.

Notable

  • An institutional network: addresses serve classrooms, studios, labs, and college services rather than commercial subscribers.
  • A full class-B allocation for a single college is a mark of how generously address space was handed out in the mid-1990s.

Interesting

  • Sheridan is best known internationally for its animation and illustration programs, so a good share of what this network carries is student media work rather than conventional academic computing.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
