You are paying for the Internet Service that your Internet Service Provider provides. That is, all data traffic that passes through their routers.

They pay to keep all their hardware running, lease the physical connection to your house (or similar for GPRS/wireless/satellite links), and pay for all the data you send and receive to other machines in the world, the bandwidth for which they purchase from trunking service providers.

You need to cover their costs, as well as pay them for providing the service at all.


You are primarily paying for actual physical Internet Access (DSL, Cable, Fibre, Wireless, Satellite, Dial-up etc) and possibly other services:

  • email
  • web hosting
  • voice over ip

DNS will be provided for free.


The ability to reach google's DNS server - and anything else not in your house. Such as this website.
