When you add a domain as hosted in some account, you usually set a pair of Name Servers to direct it to that particular provider. On their end, 3 records are set up automatically right after the domain is added - one A record and two MX records. The former is a numeric address, or IP address, that “tells” the domain address where its website is, while the other two are alphanumeric and they reveal the server that deals with the emails for that specific Internet domain. The site and the email hosting are typically thought to be one thing, while they're in fact two different services. Having separate records for them will permit you to have them with different providers if you wish. For example, some new provider could have outstanding uptime for your website, but you may not want to switch your e-mail messages from your current host and by employing an A record to point the domain to the former and MX records to have the e-mails with the latter, you could get the best of both companies. These records are checked whenever you want to open a website or send an email - in either case, the provider whose name servers are used for the domain name is going to be contacted to retrieve the A and MX records and if you have 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 will be delivered.
Custom MX and A Records in Shared Hosting
If you have a shared hosting account with our company and you wish to move either your site or your e-mails to another company, it's going to take you literally just two mouse clicks to do this. Our Hepsia Control Panel comes with an easy-to-use DNS Records tool, where all your domain names 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 want to use a different email provider and they ask you to create more MX records than the standard two, it's not going to take more than a couple of clicks either to add them. You could also set different latency for these records and the lower the latency, the bigger the priority a given MX record will have. The propagation of every record that you modify or set up isn't going to take more than several hours and if required, 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.
