IP address starting with 192- and 10-
 

This is to whomever gave the advice to block all users with the ip address of 192-or 10- users. I was under the impression they were leafs that had no files to offer. So i took this persons advice and blocked all these users which started with the said IP #. I looked on the net and it gave me my IP address, something starting with a 6... Well in my system preferences (FYI) on my macOSX notebook computer using wireless internet it states my IP address begins with a 192...
Maybe my network configured the info. wrong and my real IP starts with a 6..., but before i trust a internet site, i would love an explation as to how my computer got so confused. I am not freeloader on the limewire system. Ive been an ultrapeer many times, and ive got files to share, worthy of thou.
:p
Im taking off the restrictions i placed on IP addresses unless someone can convice me my computer is wrong.
