Summary

George Brown Polytechnic

Canada · AI-generated

education business canada

GBCAAT is operated by The George Brown College of Applied Arts and Technology, a publicly funded college in Toronto, Ontario.

What it's used for

  • The address space carries internal college infrastructure, as indicated by the netname NETBLK-GBROWNC and the registrant identity.
  • The AS announces 1024 IPv4 addresses within a single prefix (198.96.84.0/22) and maintains 2 observed neighbours, a ratio consistent with a small, self-contained institutional network rather than a transit or large-scale access provider.
  • Traffic from this AS consists of staff, students, and administrative systems for the college, including web services, email, and internal applications.

Notable

  • The RDAP registrant The George Brown College of Applied Arts and Technology matches the AS handle and the announced prefix netname.
  • The institution rebranded as George Brown Polytechnic in 2025, though the registry name retains the older "College of Applied Arts and Technology" designation.
  • The inventory consists of a single contiguous IPv4 block with no IPv6 prefixes announced.

Reputation

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 1,783 prefixes, as published 2026-10-17. 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.
