The hosts file is a plain-text operating system file that maps hostnames to IP addresses. Before your computer queries a DNS server, it checks the hosts file. By redirecting a domain to 127.0.0.1 (your own machine) or 0.0.0.0 (a null address), you effectively "block" that domain.
Adobe’s software (Photoshop, Premiere Pro, After Effects, Illustrator, etc.) constantly checks in with several licensing and validation servers. These checks verify subscription status, trial periods, and collect usage analytics. For users who have purchased a legitimate license but want to disable telemetry, or for those testing software in isolated environments, blocking these domains is a standard technique.

While Adobe frequently changes and rotates their server IP addresses and domain names to bypass these blocks, the following domains are historically the most commonly blocked endpoints.

If you use Adobe software (Photoshop, Premiere Pro, After Effects, etc.), you may want to prevent it from connecting to Adobe’s licensing servers. While we do not condone piracy, blocking these domains is a standard troubleshooting method for preventing constant trial nag screens, disabling automatic background updates, or stopping "Unlicensed software" pop-ups in legitimate, already-purchased software that is checking too aggressively.
Here is the top block list to add to your hosts file (C:\Windows\System32\drivers\etc\hosts on Windows or /etc/hosts on Mac/Linux). While Adobe frequently changes and rotates their server
If you have ever searched for ways to manage Adobe Creative Cloud licensing, reduce background telemetry, or simply stop Adobe apps from "phoning home," you have likely encountered the term Hosts File Block List. Specifically, the Adobe hosts file block list top entries are among the most critical components for users looking to control how Adobe software communicates with its activation servers.
In this guide, we will break down everything you need to know: what the hosts file is, why Adobe targets specific domains, the top 30+ block list entries you should consider, step-by-step setup instructions for Windows and macOS, and common troubleshooting pitfalls.
Some users prefer to freeze a working version and block updates:
