Block Sketchup Host File Free [top] | Trusted Source

To block SketchUp from communicating with its servers for free, you can manually edit your computer's hosts file

Methods to Block SketchUp from Accessing the Host File

• Windows: C:\Windows\System32\drivers\etc\hosts
• macOS/Linux: /etc/hosts

1. Check for Typos: 127.0.0.1 license.sketchup.com (Space between IP and domain – no "https://" or slashes).
2. Hidden Extensions: Ensure the file is saved as hosts (not hosts.txt). In Windows File Explorer, enable "File name extensions" to see the truth.
3. DNS Cache: Reboot your computer. A restart always clears the DNS cache completely.
4. IPv6: Some modern SketchUp versions use IPv6. Try adding ::1 license.sketchup.com (IPv6 equivalent of 127.0.0.1) below your IPv4 rules.
