A unique number that's assigned to every computer or other device that connects to the Internet.
- Internet Protocol (IP) addresses are assigned to Internet devices by Internet Service Providers (ISPs). Sometimes, ISPs such as AOL assign the same IP address to a large number of computers. As a result, multiple computers may have identical IP addresses.
- IP addresses can often be used to identify the location from which a computer is connecting to the Internet. When you set location targeting for your ad campaign, IP addresses help AdWords know which customers seem to be using a computer in your targeted region
- You can use IP exclusion to help prevent your ad from showing to a particular IP address.
