About this network

Yahoo (YAHOO-1) — the veteran web portal, search, and email provider, still serving a large mail and media audience.

What it's used for

• Yahoo's own services: Yahoo Mail, the Yahoo portal, Yahoo Finance/Sports, and related media properties.

Notable

• First-party services rather than third-party hosting.
• Yahoo (with AOL) now sits under the "Yahoo Inc." group owned by Apollo Global Management, after years inside Verizon.

Interesting

• Yahoo was one of the internet's defining early portals; its network still carries one of the larger webmail user bases despite the company's decline from its dot-com peak.
