I got to find that notation useful once, to make a shorter one-liner... without even knowing that there were different classes of IPv4 address, and that I was looking at one of them.
It's a tiny function that gives me the IP address of my machine in the LAN, for either Linux and Mac:
# Get main local IP address from the default external route (Internet gateway)
iplan() {
# Note: "1" is shorthand for "1.0.0.0"
case "$OSTYPE" in
linux*) ip -4 -oneline route get 1 | grep -Po 'src \K([\d.]+)' ;;
darwin*) ipconfig getifaddr "$(route -n get 1 | sed -n 's/.*interface: //p')" ;;
esac
}
(sorry to people reading on small screens)
Full disclosure, I got the "1 is shorthand for 1.0.0.0" from here (which didn't get into explaining why it is a shorthand): https://stackoverflow.com/a/25851186
