DNS stands for Domain Name Service and/or Domain Name Servers. The Domain Name Service (DNS) can be thought of much like a phone book. If you need to call someone on their phone but only have their name, you can always check the phone book for their number. The same thing happens on the Internet, although, it all happens in the background.
Like a person’s name, it’s easier to remember a domain name like rocketspark.com as opposed to their online internet address (IP), the IP address is where all the files are located that make up a website. So when you type in rocketspark.com, it checks the directory to find the (IP) address of where all the files are stored before making the connection to retrieve and display the website.
What are MX Records:
MX stands for Mail eXchange. MX Records tell email delivery agents where they should deliver your email. You can have many MX records for a domain, providing a way to have redundancy and ensure that email will always be delivered.
What are TXT Records:
A TXT (T
) record is an informational record you can use to provide additional information about the named service. You can use a TXT record to include notes about a host, or you can format it to provide technical information to servers.
What is an A Record:
An A Record (or 'A
') specifies which IP is assigned to a particular domain. This is a setting that can point your domain to your website without changing anything else on your domain. So if you’re not wanting to change all settings on your domain in one foul swoop (as by changing the nameserver settings), using an A Record will allow you to just dictate where your domain is pointing and leave everything else as is.
What is a CNAME:
stands for C
. CNAME records can be used to alias one name to another. For example, if you setup a CNAME, it should look like this:
www.yourdomain.com CNAME yourdomain.com
This is an important step as putting this in place will make sure that you can be found at both www.yourdomain.com and yourdomain.com.
