WebGo has provided the following article as a reference to the most essential records you will come across, and what DNS means. This information should help you to understand what reach record does for your domain.
DNS stands for Domain Name System is a naming system that utilises various information with domain names assigned to each computer, service, or resource.
Record Types:
A - A records are what tie host names to IP addresses. These records are critical to have since they are responsible for listing what IP address your domain is hosted on. If the A record is incorrect, you will not be able to access your domain, FTP, or email accounts. Essentially this is the internet equivalent of an entry in a telephone book that has your name, phone number ,and address.
CNAME - Identifies one domain name as the alias of another domain name. A good example of this would be if you have yourdomain.com and want it pointed to www you would add www in the name field and @ in the alias field.
NS (Name Server) - Displays the specific hostname used to search for a domain. This would be similar to an Apartment Complex. The individual apartments would be a domain and the Apartment Complex itself would be the host name "hosting" the domain.
MX - MX records are used to tell the internet where to deliver mail for your domain. You can have multiple MX records that will be tried in order of priority, with 0 being the highest priority.
TXT- This record is used for various services that need to read the information it contains. SPF records, for example, are actually TXT records that contain SPF information.
SRV - Provides information about services that are available on specific ports on your server.
We do not enable this feature by default on our Shared/Reseller servers as improper entries made to zone files can corrupt the entire nameserver service and impact other clients hosted on the server. This privilege is enabled as a courtesy. If at any time we discover an issue that arises from an entry you edited/created, we may remove your access from the Advanced DNS Zone Editor without notice. Please keep in mind that your package is fully managed. We would be more than happy to make any DNS Zone File entries for you.
