The term “hosting” does not describe just one service, but a set of services that provide a variety of functions to a domain name. Having a website and emails, as an example, are two separate services despite the fact that in the general case they come together, so most people see them as one single service. In reality, every single domain name has a couple of DNS records called A and MX, which show the server that handles each specific service - the former is a numeric IP address, that defines where the website for the domain is loaded from, while the second one is an alphanumeric string, which shows the server that handles the emails for the domain address. As an example, an A record is 123.123.123.123 and an MX record is mx1.domain.com. Every time you open a website or send an email, the global DNS servers are contacted to check the name servers that a Internet domain has and the traffic/message is first directed to that company. In case you have custom records on their end, the web browser request or the email will be forwarded to the correct server. The reasoning behind using separate records is that the two services work with different web protocols and you may have your website hosted by one company and the emails by another.
Custom MX and A Records in Shared Hosting
If you have a shared hosting account through our company and you would like to move either your website or your emails to an alternative service provider, it is going to take you literally only two clicks to do this. Our Hepsia CP 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 edit the A and/or MX records for any of them. If you choose to use a different e-mail provider and they ask you to create more MX records than the default 2, it won't 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 higher the priority a given MX record will have. The propagation of each record that you modify or set up will not take more than several hours and if necessary, 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 changed or deleted.
