Lets say I buy a domain from godaddy.com for about . Let’s say the domain is:
yahoo-answers.info
When I type in ‘yahoo-answers.info’ how does it know where to take me? How does GoDaddy put the domain on the internet? If I were to go somewhere else with my domain, I could transfer it and it would still work. o how is that?
Why can’t you register yourself a domain. How could you start a web hosting business and sell domains to people?
Domain names are registered in a database using domain name servers, or dns for short. Basically there is a load of servers which contain the url of the server where that specific domain is hosted.
Once it gets to that server, it double checks it’s domains table to see if that domain is hosted there, and if so loads the files that are hosted under that domain name.
When you transfer a domain name, you usually update the dns records for that domain, which in turn causes the initial records to be updated with the new IP address of where that name server is located. Then the checks resume from there whensomeone tries to access the site. Domain name transfers normally take up to 7 days to fully update on all name servers.
Domains, such as .com and .co.uk are registered by domain name registrars (which is where the initial check takes place). For example, the registrar for .co.uk domains is Nominet. They hold the records about that domain name and all other .co.uk domains and it redirects each link to the appropriate server once someone tries to access that site.
If you wish to sell domain names to people, there are several reseller programs out there that you can join. The majority of them are subscription services (you have to pay to join), but there are some free ones out there if you are willing to take the time to look for them.
