When looking up a bare name in DNS, the network stack will add the search domains to it to form fully qualified domain names, and look up those as well.[8] For example, if the domain search list contains "wikipedia.org", typing "en" in the browser will direct the user to "en.wikipedia.org". Some ISPs add their own search domains via DHCP settings, similar to how they add DNS servers and other networking information; if this is undesired, the user can change this setting to ".local".

Relative names are either taken relative to a well known origin, or to a list of domains used as a search list. Relative names appear mostly at the user interface, where their interpretation varies from implementation to implementation, and in master files, where they are relative to a single origin domain name. The most common interpretation uses the root "." as either the single origin or as one of the members of the search list, so a multi-label relative name is often one where the trailing dot has been omitted to save typing.
Make sure you can use their SMTP servers for outgoing email. Many hosting and domain name registration providers will not let you use their SMTP servers for sending emails. They assume you can send email via your internet server provider’s SMTP servers. However, a great many ISPs and broadband providers will only let you use their SMTP servers on their branded email accounts (i.e. [email protected]). This means that if you use your own email address (i.e. [email protected]), you won’t be able to send email via their SMTP servers. There are workarounds but you shouldn’t have to go to the trouble.
Make sure you always retain control of your domain name. There are hundreds of businesses hosting their websites with a web host they’re not happy with. Poor service, surprise invoices, unreliable uptime and email issues are just some of the common issues customers are facing today. What most of them want to do is vote with their feet and walk out the door and find another web hosting provider. They don’t go through with it, however, because moving all their domains to another host is a complete admin headache. Choose wisely from the get-go so you don’t become one of these customers.

Domain names can be used in a number of ways. Direct visitors to your website’s home page or use complementary domains to send them to specific areas of your website ( e.g. yourcompany.jobs for a careers page). Or, forward a custom domain to an existing social media account, like your Twitter profile or Periscope channel. With a domain name you can even set up custom email addresses like [email protected], which can be used to conduct business or communicate with your followers. More.
Is there another way? Yes, there is. Businesses should be making use of a domain name registration company to centrally administer all their domains. There are lots of very professional domain name registration companies that have been in business for years and that provide fully functional control panels that give their customers full control over their domain names. Then, all they have to do is change the name server details from their old host to their new host for each domain.

A short, one-word name (ex. cat.com), and especially .com domains, will be pricy because simple titles have a lot of potential uses, meaning people probably already check them out on their own. If you are going after a registered .com domain, you will have to contact the current owner, and even then, prices could be high for misspellings and multiple word domains. In the past years, companies and individuals have settled for bizarre names, misspellings, and old tricks like adding “the” or “my” to the front; note, however, that this will also reduce domain performance.
Most people assume a domain name ends in .com so if you buy a domain name with one of the other extensions (.net, .info, .org, etc.), you’ll have some extra work to get people to remember that your site has a different extension. Don’t automatically assume you should only buy domains with .com, though. Many sites have done quite well with other extensions. (Look at us!)
Many online shops have the number 24 in them, to signify 24 hours a day – you may also be able to integrate numbers into your domain in a meaningful way to make them unique. Be careful though, because many cultures attach a lot of significance to certain numbers. Make sure that your number doesn't represent bad luck or other negative things in the country you're operating in.
