If you run `host` with https://google.com, this strips the https://

host

#!/bin/sh

# cp host /usr/local/bin/
# I only use host for checking records, and 9 times out of 10
# I copy paste the url from my browser. Chrome adds http[s]://

if [ -n "$1" ]
    then
        # 1 parameter, let's do this thing
        /usr/bin/host ${1#*//}
    else
        # Carry on
        /usr/bin/host "$@"
fi

Actually, Chrome also adds a trailing /. I made an attempt to remove it, but I only got i working with zsh. Take a look at my fork if you want.
