For example, only organizations can register a “.org” domain name, and only American citizens can register a domain name that ends in “.us.” Failing to meet the guidelines and requirements for each type of domain during the actual registration and payment process will result in the domain name being “released” back into the pool of available domain names; the customer will have to pick a top level domain for which they actually qualify, or cancel their purchase altogether.
Why should you upgrade to a VPS or Dedicated Server? This may have to do with the type of site you have. If you have a lot of photos and videos that are password protected, this may be against your host’s rules for shared accounts which often prohibit file storage. Or you have a lot of site visitors, the metaphorical guests in your apartment, and your account may start getting crowded as those guests start clogging up the “hallways” otherwise known as CPU capacity. Another reason is to have full control over the configuration of your server, if you own a house you can make modifications you may not be allowed to make in an apartment or townhome.
Many services offer a low "starting price," but require you to prepay for two or three years of service to get that price. After the promotional period, the renewal price for some services can be two, three, or even four times the initial promotional pricing. While the initial deal might be incredible, the cost of transferring your site (or paying the added fee) in a couple of years may be something to consider.
