How To Setup DNS

If you’ve read the previous pages you should have chosen and bought a domain name, chosen and registered hosting with a dedicated hosting company or setup a dedicated server for your hosting requirements. If you haven’t then I suggest going to the first page in this ‘How To Become A Domainer’ guide here.

Let’s now take a more indepth look at setting up your Domain Name Servers (DNS). I’ll explain the common DNS records that you need to be aware of below.

A – an A record is short for address record and it maps from IP address to a domain name. The A record is also commonly known as a host or hostname.

CNAME – a CNAME record stands for a canonical name which is a distinct DNS record that is used to create an alias hostname from another hostname or host IP address. An example of this would be if you had several subdomains, such as: ftp.mydomain.com, mail.mydomain.com, etc. and you want them all to point towards your main domain mydomain.com.

MX – is a Mail Exchanger and this type of DNS record allows you to control the delivery of mail for a given domain or subdomain. MX can be setup on a host-by-host basis to other hosts on the internet to accept and/ or route email to your host or hosts. You can also setup a backup MX so that if the mail fails to deliver to your primary host it will send to the secondary host you specify.

TXT – is short for text record and is a resource record in DNS that allows you to enter text sources outside of your domain name. It can be used for various purposes such as domain ownership information and email security, etc.

For your purposes with a simple website like this one you’ll just need to change the A record in your domain name registrar’s DNS settings.

  1. In the first box called ‘Name’ you should type the ‘@’ symbol. The ‘@’ symbol is a catch-all address for the entire domain and this may differ between the different control panels that are commonly used, so you’ll have to refer to documentation for your specific control panel to find out which catch-all address symbol it uses.

2. In the second box called ‘Data’ you should enter the IP address of your host or dedicated server.

3. Finally, in the third box called ‘TTL’ it is commonly set to ‘3600’. Time to live (TTL) refers to the amount of time in seconds that one of the DNS settings remains current.

That’s it! You’re done setting up your Domain Name Server(DNS) settings. In the next blog post we’ll install a WordPress content management system. Have a great day and don’t forget to comment below if you need to ask any questions. Now go to the next page in this guide ‘Setting Up WordPress.’
