About this network

Two netnames end in hexadecimal, and a third carries a fifteen-digit account number.

What it's used for

• A regional internet service provider. 5,120 addresses across six IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

• 207.14.36.0/22 and 207.14.32.0/23 are both netname SPRINT-CF0E27, a carrier name and six hexadecimal characters.
• 208.8.160.0/22 follows the same pattern as SPRINT-D008A3.
• 208.7.39.0/24 is netname FON-349012966432895, three letters and fifteen digits.
• All four of those are registered to the provider despite carrying a carrier's naming.
• 204.87.157.0/24 belongs to a physicians' services company.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• Hexadecimal in a netname is a database key that escaped into a human-readable field. Six hex digits is the size of an internal record identifier, and printing it in the registry means the carrier's provisioning system wrote the record rather than a person.
• The fifteen-digit number is the same idea taken further: long enough to be an account or circuit reference, and useless to anyone outside the company that issued it.
• A medical services block routed by a small provider is the local arrangement these networks exist for.
