About this network

The netname, the handle and the holder are three company names in reverse chronological order.

What it's used for

• A utility's network. Eighteen IPv4 prefixes announced from the United States, no sixth-version space, nine thousand seven hundred and twenty-eight addresses, through five observed BGP neighbours.

Notable

• Every block carries one netname: three initials, a city, and a counter reading one.
• Those three initials belong to a company name older than anything else in the record.
• The AS handle is a different name again, two words run together, one the utility used between the initials and the name it has now.
• The holder line and every registrant give the current name.
• All eighteen blocks come from a single parent range, at four sizes, and eighteen addresses were queried for reverse DNS with none returning a name.

Interesting

• Three fields, three names, oldest label first. The netname was set when the space was granted and has never been touched; the handle was set at a later rename and then frozen in turn; only the registrant is maintained. Reading the record top to bottom walks backwards through the company's history.
• Eighteen prefixes carved from one range under one label is a network that has been subdivided many times for internal reasons and never re-registered. The registry sees one thing; the routing table sees eighteen.
• A city in the netname on a utility's space marks where the operation started, which for an electricity company is also where the wires are.
