About this network

The one host that answers a reverse lookup is a mapping server, at a company that runs dialysis clinics.

What it's used for

• A healthcare provider's corporate network. 7,168 addresses across 12 IPv4 prefixes and four IPv6 prefixes, with three observed BGP neighbours.

Notable

• Four blocks carry the netname DAVITA-NET; seven carry DAVITA-TAC1423PAC with an extra contact entry reading NetSys.
• The lookup for 96.46.231.0/24 failed, so nothing is known about that record.
• One of eighteen sampled addresses returned a name: arcgis.davita.com.
• The four IPv6 prefixes are 2620:11d:9000::/48, 2620:11d:9002::/47, 2620:11d:9004::/46 and 2620:11d:9008::/45, each twice the size of the last.

Interesting

• A geographic mapping server is the sort of thing a clinic operator needs and nobody expects: hundreds of treatment centres have to be placed, staffed and reached by patients who cannot travel far. The address footprint is unremarkable; the one name that leaks says what the network is actually for.
• That second netname is a work order rather than a description. A run of letters and digits ending in a location-like suffix is what an ordering system produces when a company buys address space through its network team, and the extra contact entry names that team.
• The IPv6 ladder is a single allocation announced as four widening pieces from one starting point, the standard shape of space carved by hand from a single grant.
