AS12844 announces 23 IPv4 prefixes covering 77,056 addresses and 0 IPv6 prefixes.

About this network

A carrier's business arm whose netnames read as a customer list: an engineering school, a county council, and a block leased from a British broadcaster.

What it's used for

• The business-services network of a French mobile and fixed carrier. 77,056 addresses across 23 IPv4 prefixes, fourteen observed BGP neighbours, and no IPv6 announced.

Notable

• The largest block is 159.31.0.0/16, netname FR-MINES-ALES, registered to a French engineering school.
• 185.183.0.0/22 is FR-CD42-20161220, registered to a French département.
• 78.105.164.0/22 is SKY-LEASED-IPXO, registered to a British broadcaster with a leasing hostmaster contact.
• Several blocks use an internal template: MODMI-158-173-248-0, MODMI-158-173-28-0, MODMI-158-173-148-0.
• Eighteen addresses were sampled and none returned a name.

Interesting

• A whole legacy /16 held by a school and announced by a carrier is the ordinary outcome of an early allocation meeting a modern outsourcing contract. The school still owns 65,536 addresses it obtained when they were free for the asking.
• SKY-LEASED-IPXO names an address-leasing marketplace. IPv4 exhaustion turned addresses into an asset class, so an organisation with spare space rents it out and it turns up announced by an unrelated carrier in another country. The netname is the only trace of the transaction.
• MODMI-158-173-248-0 builds the netname from the block's own address with dots replaced by hyphens. Generating identifiers mechanically guarantees uniqueness and readability at the cost of saying anything about what the block is for, and a carrier with hundreds of customer assignments will take that trade every time.
