When your web browser or email application requests a web page or email from another computer on the Internet, it automatically gives that computer the address to which it should send the information. This is known as your computer's ‘IP address’. (IP stands for ‘Internet protocol’.) For most users accessing the Internet from a dial-up Internet service provider (ISP), the IP address will be different every time you log in.

Information collection and use practices

  • Yahoo generally receives IP addresses from all users of all services.
  • Your IP address is also stored in our user registration databases when you register with Yahoo.
  • IP addresses can be used for various purposes, including to:
    • Diagnose service or technology issues reported by our users or engineers that are associated with the IP addresses controlled by a specific web company or ISP.
    • Send the most appropriate advertising to your computers and other devices based on geographic area or information derived from your IP address.
    • Associate users and/or devices in a similar location, such as in a household.
    • Report aggregate or other non-personally identifiable information derived from IP addresses to advertisers.
    • Estimate the total number of users visiting Yahoo from specific countries or regions around the world.
    • Assist merchants in Yahoo Stores and Yahoo Shopping to track visits to and business in their shops.
    • Help determine which users have access privileges to certain content that we host.


  • When a Yahoo web page is requested and viewed, that request is logged on our servers with information including the IP address of the device that requested the page.
  • Yahoo Mailincludes IP addresses in outgoing email message headers, as specified by standard Internet protocol.
  • Yahoo Messengersometimes uses peer-to-peer connections during operation, including times when you may be using it for instant messaging (text conversations), file sharing and webcam streaming. Peer-to-peer means that your computer connects directly to the other user's computer in the conversation without needing to go through Yahoo servers. As such, your IP address is available to users with whom you share a peer-to-peer connection.
