Then pfSense will find (and recheck every 5 minutes) the corresponding IP address(es) and put them in a table in pf. That way if the site does change its IP address, or have multiple addresses, that will be coped with.

Identify the range simply by pinging from a command prompt, you can put the result into a who is IP search to get the full range although the single IP returned should be sufficient.
