Q uses something akin to TOR, a series of rapid successive hops through anonymizing servers, so one cannot tell the true IP address of the original source, from the final message.
I was not clear. Not looking for Q’s address, but a repository of information for which it is presumed Q has provided an encryption key somewhere in his messages, or which was provided independently by JA of WL. The key is no good, of course, unless you have a link to the IP address that contains the documents.
(Wherever it is, lets hope its not on Oak Island and does not involve the Knights Templar.)
