About this network

One block, two upstreams, and a handle carrying a code that nothing else explains.

What it's used for

• A small university's network. A single IPv4 /24 announced from the United States, no IPv6, and two observed BGP neighbours.

Notable

• The AS handle appends a three-letter code and a counter to the university's name, and neither the code nor the counter appears in any other field of the record.
• The netname is the university's name with a type word attached, and the registrant is the full institution.
• Three addresses were queried for reverse DNS and none returned a name.
• Two hundred and fifty-six addresses is the entire announced footprint.

Interesting

• A single /24 behind two upstreams is a university running its own AS number purely for redundancy. The addresses are portable, so either upstream can be dropped without renumbering, and that portability is the only thing the AS number buys at this size.
• The unexplained code in the handle is the most common defect in this range. Handles are registered once, at a moment when the code meant something to whoever typed it, and then outlive that meaning entirely. There is no field where the expansion would be recorded even if someone remembered it.
• Nothing answering in reverse across a campus block means students and staff reach the internet through addresses that identify only the institution, not the building or the service.
