AS13845 announces 8 IPv4 prefixes covering 6,656 addresses and 1 IPv6 prefixes.

About this network

Five different registrants under one AS, and one of them is a corporate registration number instead of a name.

What it's used for

• A data centre operator. 6,656 addresses across 13 IPv4 prefixes, the IPv6 block 2600:3000:5100::/40, and nine observed BGP neighbours.

Notable

• 148.66.252.0/22 is registered to C06270771, an identifier where a company name belongs.
• Other blocks belong to the operator, to a computer technologies firm, to a carrier, and to a research and education network.
• Seven blocks share netname EDC-83 despite sitting in four unrelated parent ranges.
• One block is netname NETEL-ARIN-BLK09, naming a predecessor, a registry and a counter.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• A registrant field holding a filing number is the record working as a database key and failing as a document. Whoever reads it has to look the number up in a national companies register before they know who to contact, and abuse handling rarely gets that far.
• A research network's block routed by a commercial data centre is the visible edge of a colocation arrangement: the university network keeps its registration and hands the routing to the building.
• Seven blocks under one netname makes the operator's own records the least specific of the five.
