Summary

Simcoe County District School Board

Canada · AI-generated

education business canada

AS-SCDSB is operated by Simcoe County District School Board.

What it's used for

  • The address space carries educational infrastructure, evidenced by the netname SCDSB-EDU and registrant Simcoe County District School Board; Assistant Manager - Technology across all prefixes.
  • The AS announces 6144 IPv4 addresses across 3 prefixes with only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or large-scale access provider.

Notable

  • All registrants align with the announcer, consistently identifying the Simcoe County District School Board.
  • The inventory consists of three IPv4 blocks (205.211.96.0/20, 205.211.116.0/22, 205.211.120.0/22) with no IPv6 prefixes, reflecting a traditional IPv4-only deployment for a regional school board.

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 1,784 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.
