A record (Address Record) points a domain or subdomain to an IP address. For example, you can use it for store.website.com or blog.website.com and point it to where you have your store. This is a common practice for people who use Amazon, eBay, Tumblr, etc.
DNS records are used to control the location of a resource on the Internet. As an example, an A Record is used to point a logical domain name, such as "google.com", to the IP address of Google's hosting server, "22.214.171.124".
These records point traffic from example.com (indicated by @) and ftp.example.com to the IP address 126.96.36.199. They also point localhost.example.com to the server that the domain is hosted on. This allows the end user to type in a human-readable domain, while the computer can continue to work with numbers.
- Zone File:
This is where all the DNS records are stored for a domain.
- Host Record:
This is the domain or subdomain you wish to use. The @ symbol is used to indicate the root domain itself. In our example the Host Record 'ftp' would be for the subdomain ftp.google.com and '@' would be google.com itself.
- Points to:
This is the destination server that the domain or subdomain is sending the traffic to.
- The 'time to live' value indicates the amount of time the record is cached by a DNS Server, such as your Internet service provider. The default (and lowest accepted) value is 14400 seconds (4 hours). You do not normally need to modify this value.
This allows you to modify or remove existing records.
