enterprise education legacy

The network of the education software company behind the Canvas learning platform.

What it's used for

  • Corporate connectivity. 256 addresses in one /24 with two observed BGP neighbours and no IPv6 announced.

Notable

  • The single prefix, 216.51.95.0/24, carries the netname XOXO-216-51-95-0 and is registered to Instructure — a label generated in XO Communications' scheme, on a block that has since changed hands.
  • The AS handle is INSTRUCTURE-MAIN, which implies there are others.
  • It first appears in routing data in 2012.

Interesting

  • The 2012 date is the useful part of this record. AS12254 sits in a range issued around the turn of the century, and the number alone would suggest a network as old as its neighbours in this block. It is not. AS numbers are returned and reissued, so a low number can belong to a company founded a decade after the number was first handed out. Age has to be read from the routing history, never from the digits.
  • A company whose product is a learning platform used by millions of students announces one /24. The platform runs in a cloud provider's addresses; this is the office.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-01, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
