Every single registered domain has no less than two Name Server records which show where it's hosted i.e. by using these records you direct your domain address to the servers of a particular website hosting company. This way, you have got both your site and your e-mails managed by the very same provider. On the lower level of the Domain Name System (DNS), on the other hand, there are a number of other records, for instance A and MX. The first one reveals which server manages the site for a given domain and is always an IP address (123.123.123.123), while the second one reveals which server deals with the emails and is always an alphanumeric string (mx1.domain.com). As an example, when you type a domain address in your browser, your request is directed through the global DNS system to the company whose NS records the domain uses and from there you may be sent to the servers of a different company provided you have set an IP address of the latter as an A record for your Internet domain. Having different records for the website and the emails means that you can have your site and your e-mails with two different providers if you'd like.
Custom MX and A Records in Shared Web Hosting
If you have a shared web hosting account through our company and you want to switch either your website or your emails to another company, it is going to take you literally simply 2 mouse clicks to do this. Our Hepsia Control Panel provides an easy-to-use DNS Records tool, where all your domain names and subdomains will be listed alphabetically and you'll be able to see and edit the A and/or MX records for any of them. If you decide to use a different e-mail provider and they ask you to set up more MX records than the default 2, it is not going to take more than a few mouse clicks either to add them. You may also set different latency for these records and the lower the latency, the greater the priority a particular MX record will have. The propagation of any record that you modify or create isn't going to take more than a few hours and if needed, you will also be able to set the so-called Time-To-Live value, that indicates how long a record will remain active after it is changed or deleted.
