AS15188 K12ITC

Three names for one operator: a company, a schools brand, and a transit provider on two of the blocks.

What it's used for

• An IT provider serving school districts. Three IPv4 prefixes announced from the United States, no IPv6, and five observed BGP neighbours.

Notable

• The AS handle is a schools-IT brand built from a grade-range abbreviation, while the holder is registered under an ordinary company name that shares no letters with it.
• Only one block is registered to that company; its netname pairs the brand with a two-letter site code.
• The other two blocks are registered to a transit provider, whose registrant field lists the company twice and an abuse desk, joined by semicolons.
• Those two netnames are the provider's name with a counter, and the counters are far apart.
• Nine addresses were queried for reverse DNS and none returned a name.

Interesting

• Three identities for one thousand addresses is the norm for a managed-services operator. The brand faces customers, the company name faces the registry, and the transit provider's name sits on the space it lends. Only the routing ties them together.
• Borrowing address space from a transit provider is convenient until the contract ends, because the blocks go back with it. The one block registered to the company itself is the part that survives a change of upstream.
• Serving school districts means these addresses front networks full of minors, and nothing in the public record says so. The brand in the handle is the only clue.
