Question

Answer 1

You can use /^([0-2]?\d{0,2}\.){3}([0-2]?\d{0,2})$/ for IPv4 Address and /^([\da-fA-F]{1,4}:){7}([\da-fA-F]{1,4})$/i for IPv6 address.

You can combine these two as /^((([0-2]?\d{0,2}\.){3}([0-2]?\d{0,2}))|(([\da-fA-F]{1,4}:){7}([\da-fA-F]{1,4})))$/i. You can find a sample here.

For Mac Address You can use /^([0-9A-F]{2}[-:]){5}[0-9A-F]{2}$/i. You can find a sample here.
