About this network

YAHOO-FC is one of the many AS numbers operated by Yahoo (registered variously to Yahoo Holdings and Oath Holdings, depending on which registry record you read). It is a small piece of Yahoo's international serving infrastructure.

What it's used for

• Edge and point-of-presence infrastructure for Yahoo's web properties, rather than a customer-facing network. Reverse DNS across its space resolves under yahoo.com, with router names pointing at Yahoo facilities.
• It is a content network: the addresses serve Yahoo's own systems, so they map to a company's servers rather than to end users.

Notable

• The footprint is deliberately scattered rather than large — a few thousand IPv4 addresses spread across the United States, Brazil, Korea and other Asia-Pacific locations, with IPv6 /48s in each region. That is the shape of distributed edge presence, not a data-centre block.
• Yahoo runs a whole family of AS numbers; this one sits inside the wider AS-YAHOO grouping and handles only part of the picture.
