Answer 1

To find an IP address from a URL, you can use nslookup . If you want only the IP address itself, you can pipe it to grep and use a lookbehind regex to filter for the part after the text "Address: ".

nslookup google.com | grep -Po "(?<=^Address: ).*"

Answer 2

What have you tried out so far? Though for starters there are a couple of tools you can use to achieve this. If using linux, nmblookup -A <hostname.com> would produce something like this Looking up status of <IP address> Let me know exactly what you want to achieve.

okello@okello-XPS-13-7390:~$ nmblookup -A google.com
Looking up status of 172.217.170.206
