This is much like the mailbox in front of your house. Change the number and you won't get mail. Every web site you visit has that address because... you want the data delivered.

I was wondering if I really need to change the IP address of my router. I just took the wireless networking class and this topic was in one of the lessons. The instructor gave an example of how easily someone can guees the ip address of a router.
I also want to know if I will still be able to use my PDA with Wi-fi if i turn MAC filtering on.
