AS13499 announces 4 IPv4 prefixes covering 12,800 addresses and 0 IPv6 prefixes.
About this network
One autonomous system announcing blocks belonging to a publisher, an insurer and a brake manufacturer.
What it's used for
- An information services company's network. 12,800 addresses across four IPv4 prefixes, five observed BGP neighbours, and no IPv6 announced.
Notable
- Two prefixes in 159.242 are netname NET-159-242-128-0-CH, registered to the holder with an Engineering contact.
- 171.18.134.0/24 is netname AXA-Partners-US, registered to an insurance group's abuse handling role.
- 192.203.181.0/24 is netname BRAKEPARTS, registered to a brake manufacturer with an IT Services contact.
- The AS handle is CH-ENT-DC-IL, naming an enterprise data centre and a location.
- Twelve addresses were queried for reverse DNS and none returned a name.
Interesting
- Three unrelated businesses sharing one autonomous system is a managed hosting arrangement seen from outside. The operator announces its tenants' address space; each tenant keeps its own registry record, so the registry shows three companies and the routing table shows one network.
- The handle spells out what the registry does not: enterprise, data centre, and the location it sits in. Somebody named this after the facility rather than the company, which is the more useful label when the company's job is running facilities.
- A brake manufacturer and an insurer in the same routing announcement have nothing in common except the vendor they both hired.
