Web Hosting Pricing & Value
Some choose web hosting providers based solely on price. While thats not a great strategy, you should certainly take pricing into consideration. The best providers offer plans for every budget and in some cases, signing up for longer subscriptions will qualify for extra discounts.
Also, leave some room to grow. Choosing a web hosting plan that meets your websites current needs is great. But, with any luck, your site will grow and expand over time, and your needs may change. Since switching to a new web hosting provider is a major hassle, consider one that offers scalable plans. Meaning, you should be able to upgrade to another plan easily once necessary. Low prices are always nice, but if the low price comes with a limit on space or bandwidth, you need to be sure the deal is really worth it.
Along the same lines, you may want to pay attention to how many email accounts are provided. Whether or not you believe youll need dozens of email addresses, its nice to have the option to create as many as possible down the line.

Master name servers
A master name server is authoritative for one or more DNS zones.Each server maintains its data in database files, and may transfer thisdata periodically to a slave server if one exists in thezone.
When a server answers a client request, it attaches an expiration for the data after whichthe data is considered invalid.The time-to-live variable is specified in theSOA resource record contained in thezone’s database file.
Master name servers should be machines that are reliable and haveexcess memory and disk storage space.
A server may serve as a master server for one or more zones and asa slave server for other zones.“An example of a master name server”shows an example of a name server that is master formynet.com but slave for its childrenrivers.mynet.com andseas.mynet.com.
