About this network

Five blocks, five upstreams, one netname, and the netname belongs to a carrier.

What it's used for

• An infrastructure company's network. Five IPv4 prefixes announced from the United States, no IPv6, two thousand and forty-eight addresses, through five observed BGP neighbours.

Notable

• The AS handle is the company's two words run together with a zero-padded numeral one. The holder writes the same two words apart with a corporate suffix.
• Neither name appears on any block. All five are registered to one large carrier, under a single netname: that carrier's brand, a hyphen, and one letter.
• The blocks are scattered across the carrier's space rather than adjacent, four at the smallest routable size and one four times larger.
• Fifteen addresses were queried for reverse DNS and none returned a name.
• Five observed neighbours carry five prefixes, one for every block.

Interesting

• One netname of a brand and a single letter, repeated across every block a carrier assigns, is the registry entry a carrier makes when it stops filling the field in. It records who owns the space and nothing about who uses it.
• Scattered blocks from one supplier are addresses handed out as they came free, not a range reserved in advance. The company took what was available and announced each piece as it arrived.
• Five upstreams on two thousand addresses is a very high ratio. Whatever runs here is bought for reachability rather than for size.
