AS12254 announces 1 IPv4 prefixes covering 256 addresses and 0 IPv6 prefixes.

About this network

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.
