About this network

A Colorado school district holding its own AS number and one /24.

What it's used for

• School district connectivity. 256 addresses in a single /24 with one observed BGP neighbour and no IPv6 announced.

Notable

• The AS handle is TSD-AS-01, numbered as if a second were expected.
• The block, 69.2.159.0/24, is netname TSDR-1, registered directly to the district.
• The netname adds an R the handle does not have.
• Present in routing data since the collectors' earliest records in August 2000.

Interesting

• Colorado school districts carry a letter-and-number designation alongside their name, and this one is Thompson R2-J. The stray R in TSDR-1 is most likely the start of that designation, clipped where the netname ran out of room.
• A district running its own autonomous system rather than sitting behind a state education network is a choice about independence. It costs an AS number, a router somebody has to understand, and a relationship with a carrier, and it buys the ability to change providers without renumbering every school.
• One neighbour means that independence is currently theoretical. The machinery for a second upstream is in place; the second upstream is not.
