AS13435 — COMMUNITY-HEALTH-CHOICE

AS13435 announces 2 IPv4 prefixes covering 768 addresses and 0 IPv6 prefixes.

About this network

Handle, netname and registrant all say the same thing, which almost never happens.

What it's used for

• A health plan's network. 768 addresses across two adjacent IPv4 prefixes, four observed BGP neighbours, and no IPv6 announced.

Notable

• The AS handle, both netnames and both registrants are all the organisation's name.
• The two prefixes, a /23 and a /24, sit next to each other inside the same /22.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• Consistency across every field is rare enough to be worth noting. Most records in this range carry an old company name in the handle, a carrier's code in the netname and a current name in the registrant, because each was written at a different time. This one was created in a single sitting and has not needed changing since.
• A /23 and a /24 announced separately out of one /22 is either two assignments that arrived apart, or a split kept for routing. With four upstreams there is a reason to keep them separate.
• Four neighbours for 768 addresses is a small network that cannot afford to be unreachable. Health plans sit between providers and payments, and both sides expect the connection to be there.
