ip

i know how IP basically works, and knows that an IP address composed of a network ID portion and a host ID portion, but when I type a IP address ,say "8.8.8.8" into the web browser, i DIDN'T supply any subnet mask information, so how does the browser know where the dividing line is between the network ID and host ID? since 8.8.8.8 may mean 8.8.8.8/8, 8.8.8.8/24 etc. In a nutshell, the IP address I supplied is ambiguous.
