I just needed to store the LAN IP (for ipv4) in a variable for a specific task in a bash script. I figured I'd share. I sent it to a variable with VAR=$(stuff) and used it later on. I put the exit 0 in the if statement to make it so that it breaks if there are more than one IPv4 addresses assigned. I only wanted the first one.
