A simple script to determine your machine's internal and external IP address.
An internet connection is needed, to determine the external ip address (duh).
showip -i # Show internal IP address(es)
showip -e # Show external IP address
showip -u # Update this script
bash < <(curl -fsSL https://raw.githubusercontent.com/emazzotta/showip/master/install.sh)
ifconfig
curl
grep
