About this network

The registrant field holds a handle instead of a name.

What it's used for

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

Notable

• The registrant is written as a hyphenated identifier rather than as prose, so the field that should hold the organisation's name holds something shaped like a netname instead.
• The netname is that same string, making the two fields identical and neither of them the company's registered name.
• The AS handle is three letters that match nothing else in the record, followed by the abbreviation for autonomous system number.
• Three addresses were queried for reverse DNS and none returned a name.
• The routing history begins in 2001.

Interesting

• A registrant that is a handle rather than a name breaks the one field these records are supposed to get right. Anything matching organisations across registries has to guess that a hyphenated identifier and a company name refer to the same body, and nothing in the record says so.
• The three-letter handle is the third identifier for the same organisation, and it is derivable from none of the others. Whoever registered it knew what it stood for; the record does not.
• Two hundred and fifty-six addresses and two upstreams is an insurer that wants its addresses to survive a provider change and needs nothing else from routing.
