Some of the major things to consider when planning to host locally is the bandwidth, load, and maintenance. The most limiting of these is probably your upload bandwidth. Most ISPs, especially DSL, have much slower upload bandwidth which needs to be shared by all users reaching your site. One nice thing about many of the hosting services using virtualization, is that if some reason, your site gets popular, they replicate your site to meet the load instantly. Most of us will probably never be lucky enough to need this. Lastly, a hosted site will perform all of the security and maintenance tasks you do not want to be bothered with. In your case, the bandwidth required to the server is probably most important and should be calculated for worst case.


I think you got enough of an answer to all of your DNS questions. So I will add a few tidbits anyway! The DNS system is a hierarchical system of services on servers that translate between the domain and the server's IP address. There are a small number of root DNS Servers, which are heavily monitored because they can cause massive outages. Most people use DNS Servers running at their ISP. Your domain lookup request travels up the tree until it gets an authoritive answer or an answer that has been cached recently. Otherwise, it asks up the chain toward the root, gets an answer and returns it to your browser. It was originally designed for each domain and sometimes sub domains each have their own domain server. When I worked at GE, we set up two levels and some buildings had their own DNS server. The domain system has vastly flattened out, to where today the .com domain is huge! It is fortunate server performance has kept pace, because even DNS requirements today would have been impossible with last decade'[s hardware / software.

It is possible to manually enter DNS servers in your router and bypass your ISP for this service. Using a free service like OpenDNS.com provides extra features like adult supervision of the sites that can be viewed in your home, based on settings in your account. Strangely, this service is faster than the the DNS from the ISP.

DNS stands for Domain Name Server. Internet works on IP addresses and when
we request a domain for example, on the address bar of the browser, an FTP
client or an email server, there is a server for that domain extension, for
example a .com domain, which receives the request and through DNS entries,
knows which DNS server to send it to; and the DNS server will in turn send
it to the host that handles that domain, either as a host or virtual host.
The host server knows which account and protocol to send the request to,
whether a dedicated or shared server.
