Canada · AI-generated

TOCT is the autonomous system for The Ontario College of Teachers.

What it's used for

  • The space carries the internal network of a professional regulatory body, evidenced by the netname ONTCTUU4 and registrant Ontario College of Teachers.
  • The AS announces 256 IPv4 addresses across 1 prefix with 1 observed neighbour, indicating a small, self-contained corporate estate rather than a transit or access provider.

Notable

  • The RDAP registrant Ontario College of Teachers matches the registry holder and AS handle, confirming consistent ownership.
  • The address inventory consists of a single /24 block (209.205.40.0/24), representing a standard-sized allocation for a small organization.

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 2026-10-20. 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.
