AS13690 announces 3 IPv4 prefixes covering 1,792 addresses and 0 IPv6 prefixes.

About this network

Three blocks, three different registrants, and one of them is the address registry itself.

What it's used for

• An ambulance operator's network. 1,792 addresses across three IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

• 65.215.160.0/22 is netname UU-65-215-160, a former carrier's prefix plus the address.
• 104.218.112.0/23 is netname NET104 and is registered to the American Registry for Internet Numbers, the body that hands out the addresses.
• 104.218.114.0/24 is netname GMR-PUBLIC and is registered to a successor company under a different name.
• Nine addresses were queried for reverse DNS and none returned a name.

Interesting

• A registry appearing as the registrant of an announced block means the sub-assignment was never recorded, so the lookup falls back to the parent object that covers the whole first octet. The registry is not using the space; it is what remains when nobody filled the field in.
• The two neighbouring blocks sit side by side and are registered to two different companies, one of which absorbed the other. The rebrand reached the smaller block and stopped.
• An ambulance service is one of the few private networks where an outage is measured in response times, which is what two upstreams and a private AS number are buying here.
