Summary

Niagara Catholic District School Board

Canada · AI-generated

education school canada network

The AS handle NIAGARA-CATHOLIC-DISTRICT-SCHOOL-BOARD is held by Niagara Catholic District School Board.

What it's used for

  • The address space carries the network infrastructure for the Niagara Catholic District School Board, as indicated by the netname NCDSB and registrant Niagara Catholic District School Board for both announced prefixes.
  • The AS announces 768 IPv4 addresses across 2 prefixes and maintains 3 observed neighbours, a ratio consistent with a small, self-contained institutional network rather than a transit or large access provider.
  • Traffic from this AS consists of internal network traffic for the school board's 48 elementary schools, 8 high schools, and 4 adult education centres, supporting staff, students, and administrative operations.

Notable

  • Both registrants for the announced prefixes match the AS holder, with Niagara Catholic District School Board listed for both 216.40.64.0/23 and 192.68.163.0/24.
  • The address inventory is small and finely subdivided into two distinct blocks, reflecting the internal segmentation typical of a large educational institution managing multiple sites.

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.
