The definition of “hosting” doesn't describe a particular service, but several services that provide different functions to a domain. Having a website and e-mails, for instance, are two independent services even though in the general case they come together, so most people think of them as one single service. In reality, each and every domain name has a couple of DNS records called A and MX, which show the server that handles each particular service - the former is a numeric IP address, which identifies where the website for the domain address is loaded from, while the second one is an alphanumeric string, which shows the server that handles the e-mails for the domain name. As an example, an A record would be 220.127.116.11 and an MX record would be mx1.domain.com. Every time you open a website or send an e-mail, the global DNS servers are contacted to check the name servers that a domain has and the traffic/message is first forwarded to that company. When you have custom records on their end, the browser request or the email will be directed to the correct server. The reasoning behind using separate records is that the two services employ different web protocols and you could have your site hosted by one service provider and the e-mail messages by another.
Custom MX and A Records in Cloud Web Hosting
If you have a Linux cloud web hosting package through our company, you're going to be able to see, create and modify any A or MX record for your domain names. As long as a specific domain name has our Name Servers, you're going to be able to modify certain records via our Hepsia hosting CP and have your website or e-mails directed to any other service provider if you want to use only one of our services. Our sophisticated tool is going to allow you to have a domain address hosted here and a subdomain below it to be hosted elsewhere by changing only its A record - this will not affect the main Internet domain the slightest bit. If you decide to use the e-mail services of another company and they want you to set up more than 2 MX records, you can easily do it with simply a couple of mouse clicks in the DNS Records section of your Control Panel. You can also set different latency for each MX record i.e. which one is going to have priority.
