When you add a domain name as hosted in some account, you normally set a pair of Name Servers to point it to that particular service provider. On their end, three records are created automatically as soon as the domain is added - one A record and two MX records. The former is a numeric address, or IP address, that “tells” the domain where its site is, while the other two are alphanumeric and they show the server that manages the e-mails for that particular domain address. The site and the e-mail hosting are usually regarded as one thing, while they're in reality two different services. Having different records for them will enable you to have them with different companies if you would like. As an example, some new service provider could have fantastic uptime for your website, but you might not want to switch your e-mail messages from your current host and by using an A record to point the domain to the former and MX records to have the e-mails with the second, you will get the best of both providers. These records are checked when you want to open a site or send an email - in either case, the provider whose name servers are used for the Internet domain 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'll see the needed website or your email will be delivered.

Custom MX and A Records in Web Hosting

If you have a web hosting account from our company and you want to switch either your website or your emails to a different service provider, it'll take you literally only 2 mouse clicks to do it. Our Hepsia CP comes with an easy-to-use DNS Records tool, where all your domain names and subdomains will be listed alphabetically and you're going to be able to see and change the A and/or MX records for any of them. If you choose to use a different email provider and they ask you to set up more MX records than the default 2, it's not going to take more than a couple of clicks either to add them. You may also set different latency for these records and the lower the latency, the bigger the priority a particular MX record is going to have. The propagation of every record that you change or create won't take more than several hours and if necessary, you will also be able to set the so-called Time-To-Live value, which reveals how long a record will stay active after it is changed or deleted.
