About this network

A handle carrying one country's code, and a netname naming a block that is not the one it is on.

What it's used for

• An energy group's corporate network. Eight IPv4 prefixes announced from the United Kingdom, no IPv6, eight thousand four hundred and forty-eight addresses, across two observed BGP neighbours.

Notable

• The AS handle is the brand, a two-letter country code and the digit one. That country is not the one the blocks are announced from, and the digit implies a second handle somewhere.
• Seven of the eight blocks share a single netname: the brand and the word for a network, with no date, no country code and nothing to tell them apart.
• The eighth adds four octets to that netname, and those octets are not its own. Its third octet differs from the one the name claims.
• That eighth block is registered to the group's company in a different country, while the other seven name the international arm and a hostmaster.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• A netname built from an address is only correct until the block moves or is split, and this one is already wrong. It was copied from a neighbouring block and the octets were never updated.
• A serial number in a handle is a promise about the rest of the set. Somewhere there is meant to be a second one, and the record gives no way to find it.
