@jewfcb001 nslookup on my computer also returns the address 146.112.59.81.

If you are looking to create firewall rules to allow traffic, you might be better off creating a URL or FQDN objects, rather than creating a host object based on the IP address.

@jewfcb001 you can use FQDN objects, this relies on DNS performing a lookup. Refer to this guide:-
