About this network

NATIONWIDEASN is the corporate autonomous system of Nationwide Mutual Insurance Company, the American insurance and financial-services group headquartered at Nationwide Plaza in Columbus, Ohio.

What it's used for

AS6569 carries Nationwide's own internet connectivity. It originates the company's legacy 155.188.0.0/16 and 156.138.64.0/18 space, roughly 81,000 IPv4 addresses, plus assorted more-specifics. The addresses serve the group's offices, data centres and public-facing services.

Notable

This is an enterprise address, not a provider one. A large insurer runs an AS for the same reasons a bank does: multihoming, control of its own edge, and stable addressing for partner and agent connectivity that has to survive a change of carrier.

The /16 is a reminder of how much address space a large US enterprise could obtain in the early 1990s. ARIN registered AS6569 in May 1996.
