What is IP Masking and why is the Wikimedia Foundation masking IPs?
IP masking hides the IP addresses of unregistered editors on Wikimedia projects, fully or partially, from everyone except those who need access to fight spam, vandalism, harassment and disinformation.
Currently, anyone can edit Wikimedia wikis without a Wikimedia account or without logging in. MediaWiki, the software behind Wikimedia projects, will record and publish your IP address in its public log. Anyone seeking your IP address will find it.
Wikimedia projects have a good reason for storing and publishing IP addresses: they play a critical role in keeping vandalism and harassment off our wikis.
However, your IP address can tell where you are editing from and can be used to identify you or your device. This is of particular concern if you are editing from a territory where our wikis are deemed controversial. Publishing your IP address may allow others to locate you.
With changes to privacy laws and standards (e.g., the General Data Protection Regulation and the global conversation about privacy that it started), the Wikimedia Foundation Legal team has decided to protect user privacy by hiding IPs from the general public. However, we will continue to give access to users who need to see the addresses to protect the wikis.
We're aware that this change will impact current anti-abuse workflows. We are committed to developing tools or maintaining access to tools that can identify and block vandals, sock puppets, editors with conflicts of interest and other bad actors after IPs are masked.

Hello! Please review the new Access to temporary account IP addresses page for details about how users can gain access to IP addresses. The section on using IP addresses will be updated with details about how and where to access the IP addresses, as well as what is logged when IP addresses are accessed. Please also review a new related page with frequently asked questions. You will notice that both pages use the term "temporary user accounts," which comes from the MVP—more information about the MVP will be shared directly on this page soon. If you have questions or concerns, please reach out on the talk page.
