About this network

Every field in this record names a different AS number, and none of them is this one.

What it's used for

• A provider's network. A single IPv4 prefix announced from the United Kingdom, no IPv6, two hundred and fifty-six addresses, through one observed BGP neighbour.

Notable

• The holder field begins with the two letters for an autonomous system and a five-digit number that is not this network's number, followed by the company name.
• The AS handle is that same foreign number written twice, with nothing else in the field.
• All three queried addresses answered, and each name is the four numbers of the address as dotted labels, then two letters for an address, then the word for static, then a domain named after that other number again.
• The netname is four letters for a network operations centre, a country code and a numeral, and the only registrant is a hostmaster role carrying a brand in lower case that appears nowhere else.
• So the record names one company, one lower-case brand, and one AS number that is not the one being described.

Interesting

• Operators who run several numbers often build one naming scheme and point everything at it. The hostnames, the handle and the holder field here all reference the sibling number, which makes the relationship obvious and this record almost impossible to read on its own.
• A domain named after an AS number is stable in a way a brand is not. It survives renames and acquisitions, and it stops being accurate only if the number itself is transferred.
