|Nameserver||Nameservers “point” your domain name to the company that controls its DNS settings. Usually, this will be the company where you registered the domain name.
However, if your website is hosted by another company, sometimes you’ll need to use their nameservers.
|Zone File||Zone Files are simply the files that store all of your domain’s DNS settings. Your domain name’s Zone File is stored on the company’s nameserver.|
|A Record||A Records point your domain name to an individual server using an IP address. An example IP address is 188.8.131.52.
You can also use A Records to point subdomains (for example subdomain.coolexample.com) to a server’s IP address.
Every domain name has a primary A Record called “@,” which controls what your domain name does when some visits it directly.
|CNAME||CNAMEs point your subdomains to another server using a server name. Unlike A Records, CNAMEs cannot use IP addresses.
Most domain names have many CNAMEs.
|MX Records||MX Records point your domain name’s email to its email provider.|
