I have been reading for two days everything I can find about IP addresses, including the tutorials on this forum, Wikipedia, Whatis, how stuff works. I understand dotted quads. I understand that every device on a network needs and unique address. I understand that 4 binary octets totals 4+ billion numbers.
I have also read that the URL in a browser window is translated to an IP address. What does this have to do with a device on the internet. Every webpage on every website in the world would need a unique IP address. Add all the computers (and other devices) and there have to be more than 4 billion. There are probably a billion websites alone, If each had four pages--see what I mean.
I am just looking for some clarification.
Thanks to anyone who can enlighten me.
