About this network

Holder, handle and registrant are one word in capitals; the netname is something else entirely.

What it's used for

• A small network. A single IPv4 /23 announced from the United States, no IPv6, and two observed BGP neighbours.

Notable

• The holder name, the AS handle and the registrant are the same string, in capitals, with no corporate form and no punctuation.
• The netname is DIL-37, which shares no letters with that string and carries a counter that matches nothing else in the record.
• Three addresses were queried for reverse DNS and none returned a name.
• The routing history begins in 2000.

Interesting

• Three fields agreeing exactly and a fourth agreeing with nothing is the useful shape here. The netname was written by whoever issued the block, using their own scheme, and it survived the assignment. Nothing in the record explains what those three letters stand for, and nothing ever will.
• A holder name in bare capitals with no corporate form is common in older registrations and it makes automated matching harder than it looks: the same company written in mixed case elsewhere will not match, and there is no legal form to anchor a search on.
• Five hundred addresses behind two upstreams, nothing answering in reverse, and a name that appears nowhere else. This is what a network looks like when it has outlived the paperwork that describes it.
