The Internet, at the end of the day, is not about technology, but an agreement: I send you traffic and you move it around, and you send me traffic and I move it around.
We all agree to use the same protocols (IP, BGP) and so can talk to each other, and the moving of bits can either be on a paid (ISPs) basis or non-paid (IXPs) basis.
As part of this everyone agrees to not move certain addresses (RFC 1918), and if they come across any, they filter/drop them as soon as possible.
Another part of this agreement is various vendors agree to the same rules, so your home firewall/router (Linksys, D-Link, Asus) acts in certain ways, which includes making sure that any traffic from (e.g.) 192.168/16 does not go out the interface labelled "WAN". (Though if it does, your ISP also agrees to filter it.)
