I am not much into networking but I do have an idea how a simple network work but still have few vague concepts will be great if someone can help me with.
Now with the ISP, the provide home and businesses with Internet access.
For businesses they provide them with public ip addresses to use it as they please, web-servers, e-mails etc.
For homes? When someone gow to www.whatismyip.com
he is presented with the IP address of his ISP default gateway right?
But, how do the ISP provide internet access to homes? do home share on public IP_ address according to areas for example? I have a LAN at home and some one else might have a LAN in the same IP scope if we share the same IP router for the same provider why not connect together? No routing?
A brief description of the structure would be great the whole concept is vague in my mind.
