An overview of IP anonymization in Google Analytics
General overview of how we can achieve IP anonymization or IP masking in Google Analytics.
Internet Protocol (IP) address anonymization or masking is simply sending a visitor's IP address to Google Analytics servers by deleting/masking the last octet of the IPv4 address or the last 80 bits of the IPv6 address.
IP address anonymization occurs before any visitor's data is stored or processed by the Google servers. For the newest version of Google Analytics 4, the IP address anonymization is enabled by default and no manual action is required. For older versions, IP address anonymization is an opt-in feature that needs to be explicitly by adding a parameter to your tracking code.
The process of IP address anonymization takes place within two steps in the collection pipeline: the JavaScript Tag and Collection network:
IP address anonymization with analytics.js:
ga('set', 'anonymizeIp', true);
IP address anonymization with gtag.js:
gtag('config', '<GA_MEASUREMENT_ID>', { 'anonymize_ip': true });
IP anonymization can also be set up through Google Tag Manager (GTM) graphical settings interface.
IP anonymization for iOS is done automatically with the use of Firebase SDK or with the following line when using iOS SDK:
[tracker set:kGAIAnonymizeIp value:@"1"];
IP anonymization for Android is done with Google Analytics Services SDK for Android with the following configuration parameter:
<string name="ga_anonymizeIp">true</string>
HTTP is a protocol used to connect to web servers by web browsers to request content to view. This is also used to transfer larger files, and is often used for software updates.
The "Network Layer" handles communication over networks (how networks communicate).
An IP address refers to a specific and unique location on the Internet. The two current standards are: IPv4 and IPv6.
