Each registered domain name has at least two Name Server records that show where it's hosted i.e. by using these records you direct your Internet domain to the servers of a certain hosting company. This way, you have both your site and your e-mails managed by the very same service provider. On the lower level of the Domain Name System (DNS), however, there is a variety of other records, like A and MX. The former reveals which server deals with the site for a given domain address and is always an IP address (220.127.116.11), while the latter reveals which server manages the e-mails and is always an alphanumeric string (mx1.domain.com). As an illustration, any time you enter a domain name in your Internet browser, your request is sent through the global DNS system to the company whose NS records the domain address uses and from there you will be forwarded to the servers of another provider in case you have set an IP address of the latter as an A record for your domain. Having separate records for the website and the emails means you may have your site and your e-mails with two different providers if you would like.
Custom MX and A Records in Shared Hosting
If you have a shared hosting account from our company and you want to switch either your site or your emails to another service provider, it'll take you literally just two clicks to do it. Our Hepsia CP comes with an easy-to-use DNS Records tool, where all your domains and subdomains are going to be listed alphabetically and you will be able to see and change the A and/or MX records for any of them. If you wish to use a different e-mail provider and they ask you to set up more MX records than the default 2, it won't take more than a few mouse clicks either to add them. Also you can set different latency for these records and the lower the latency, the greater the priority a given MX record is going to have. The propagation of every record that you modify or set up will not take more than a few hours and if needed, you'll also be able to set the so-called Time-To-Live value, which reveals how long a record will remain active after it is modified or deleted.
