     The exact steps will differ according to your distribution. For example, with Ubuntu derived systems which use `systemd-resolved`, you can add the following entry to the `/etc/systemd/resolved.conf`:
 
     ```ini
     [Resolve]
     DNS=8.8.8.8
-    Domains=~nip.io.
+    Domains=~sslip.io.
     ```
 
     Then simply restart the service with `sudo service systemd-resolved restart`.
