Privatefirewall 7.0, How Block Multi-level Domain Names ?

We would like to block (with Privatefirewall 7.0, and yes we understand it is somewhat obsolescent/unsupported, but so far so good) a domain name, but not sure of the correct protocol.
In this case the Malwarebytes popup was the multi-level domain name 'east7.doyourbid.bid'.
For the Privatefirewall 'Blocked Sites' and then 'Host Name:' , do we need to type in the entire 3-level name, or just the 2-level name (ie doyourbid.bid) ?
Also, we have since seen a new 3rd level, ie 'east11.doyourbid.bid', and wonder if just the 1st 2 levels will take care of any new 3rd levels.
Thoughts ?

 

Could you try one way and then ping to see if it's blocked?

 

Thank you for the suggestion and sorry for the late reply.
Not familiar with the 'ping' command, but did a little research at https://www.lifewire.com/ping-command-2618099 and sounds like a good way to check.
Am now in the middle of trying to determine if it makes any difference if we add a duplicate URL (by mistake) to the PFW Blocked Sites 'URL/IP Address' list.
Any ideas on that one ?
Maybe should post question to new thread, or may already exists ?
