 The LookAround client uses IP multicast to find LookAround servers within the
 same multicast domain.
 
+MAC addresses change slower than IP addresses, so if you know that
+`11:11:11:11:11:11` is your laptop, and your laptop is running LookAround,
+LookAround will find the IP for you.

 ## Installation
 
 Use the Cargo package manager from [Rust](https://rustup.rs/) to install LookAround.
