Wsl2-dns NPM | npm.io

WSL2 DNS synchronizer.

Install:

Run: npm i -g wsl2-dns
From your Windows installation go to C:\Windows\System32\drivers\etc and take ownership of this file and/or make it writable from non-elevated Notepad instance. You can do that manually, but I recommend to use WinAero Tweaker to add Take ownership entry into file context menu.

How it works:

This app will update IPs of your existing domains defined in Windows' hosts file to match wsl2 distro IP address (which changes when wsl2 shuts down).

It will not add new entries.

Note that Windows does not support wildcard subdomains, so you still have to list your domains manually there even if you run wsl2-dns with wildcard subdomains specified.

Usage:

wsl2-dns domain1 [domain2 domain3 ...domainN]
^ where domain is either a full domain name to update or "wildcard" name starting with . dot to update all subdomains of that domain (excluding root domain itself!)

Example:

wsl2-dns bigproject.local .localhost
^ to update bigproject.local, small.localhost, other.localhost, but not localhost

Warning: It is not recommended to replace localhost root level domain. Some Windows apps may rely on that pointing to 127.0.0.1.

Recommended usage

put wsl2-dns command in your ~/.profile file, this way each time you start a new terminal window you will have your dns domains updated
choose single or multiple top-level domain (.localhost or any custom, I use .dzek) to avoid updating the .profile file each time you add new subdomain (remember you need to update Windows' hosts file)
