When you add a domain as hosted in some account, you typically set a pair of Name Servers to direct it to that specific provider. On their end, 3 records are created automatically when the domain address is added - one A record and two MX records. The former is a numeric address, or IP address, which “tells” the domain name where its site is, while the other two are alphanumeric and they show the server that deals with the emails for that specific domain address. The website and the e-mail hosting are usually perceived as one thing, when they're in fact two different services. Having independent records for them will permit you to have them with different companies if you'd like. For example, some new provider could have excellent uptime for your website, but you may not want to switch your emails from your current host and by employing an A record to point the domain address to the first and MX records to have the e-mails with the latter, you could get the best of both providers. These records are checked whenever you want to open a site or send an e-mail - either way, the service provider whose name servers are used for the domain name will be contacted to retrieve the A and MX records and if you've set records different from their own, the correct web/mail server will then be contacted and you will see the needed site or your email is going to be delivered.

Custom MX and A Records in Web Hosting

If you have a web hosting account with our company and you would like to move either your site or your emails to another company, it is going to take you literally just two mouse clicks to do so. 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 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 standard 2, it's not going to take more than a couple of mouse clicks either to add them. You can even set different latency for these records and the lower the latency, the greater the priority a given MX record will have. The propagation of each record that you modify or set up isn't going to take more than a few hours and if needed, you'll also be able to set the so-called Time-To-Live value, which shows how long a record will stay active after it is modified or deleted.
