Understanding DNS Records

CNAME? MX Record? If you are as confused as a chameleon in a bag of skittles fear not! DNS (Domain Name System) records are actually pretty easy to understand. 


A Record


Note: Above is your Domain's existing A Record so don't delete it! 

A stands for Address. Every website in the world has a specific numerical address called a internet protocol address (IP for short). For example the IP Address of www.google.com is (you can actually type these numbers into the url bar of your browser and it will open up Google). However these numbers would be hard for people to remember so domain names like www.yourwebsite.com were introduced. An A Record simply maps your domain to your IP Address so that when someone types in your domain, they will be forwarded to the correct IP Address. 


CNAME Record


Note: Above is your Domain's existing CNAME Record so don't delete it! 

CNAME stands for Canonical Name. You can think of this being as a type of forward. For example if you have the domains www.myhomedeals.com and myhomedeals.com, and you want both of them to go to the same files you can add www.myhomedeals.com as a CNAME Record that will then go to the same files as myhomedeals.com. 

Adding an A/CNAME record:


In the subdomian field enter www and in the address filed enter the domain name. (If it is the same domain you can enter @ for the address.)


MX Record

MX stands for mail exchange. This tells where the emails associated with your domain (mike@ibuyhomes.com) should be delivered. For example if you are using G Suite (google's email service) you would enter their MX records. Usually there are multiple MX records to add redundancy. Think of it like having 5 mailboxes by your house. If the mailman cannot get to the first one because there is a car parked in front of it, they still have 4 other ones where they can put your letter in. At the end of each MX record there is a number that tells the virtual internet mailman which one to try first (they try the lowered number ones first and only if those fail do they move onto the next). 


Adding an MX record: 

If you are using G Suite (Google Apps), Office 365, or GoDaddy for your email just click the relevant button and your MX Records will automatically be added. However you can have other email providers as well.  They would need to supply their MX records to you.  Then you would copy them into the fields.


TXT Record


Note: Above is a sample TXT. This specific one helps Client Genie send your emails so don't delete it! 

TXT stands for text. This is basically a blank note slot where you can add any information that you want. While you could type "remember mom's birthday" just kidding a more common use is to add verification text from outside parties (like G Suite) so that they can verify that the person that is applying for their services is the rightful owner of the domain. 


Adding a TXT Record:

The most common time when you would need to add a TXT Record is when setting up G Suite email. They give you a verification code and you would simply copy this into the TXT field.
