How the Domain resolution takes place?
Normally on the Internet when you request to browse a
website, your browser contacts few DNS servers on the basis of hierarchy and
authority (if the information is not already cached on your PC), to connect
you with that web server.
In case of hosting from home, the only difference is
that your visitor has to be directed to your home PC instead of a web
hosting server.
To achieve this, your PC will be sending a heart beat
to your DDNS provider like DNS2go, with your latest IP address so that when
a visitor calls for your website he is directed to you by the DDNS provider
who will be first automatically contacted by the user.
When a visitor reaches the server of dns2go or TZO or
other similar services, as directed by your registrar (in case your domain
registrar and DDNS service provider are different). Some DDNS providers do
not allow this and it may be imperative to make both DDNS provider and
domain registrar one company.
Due to their program sitting in your home PC reporting
your IP addresses to them, they are aware of your current address and direct
the visitor to you. This process completes the domain resolution and your
site is found on the Internet and at your home.
Using the same method you may be able to host an ftp
server, game server, chat server etc.
