CNAME-Canonical Name
Canonical Name records allow a server to be known by one or more hostnames. Generally, they act as an alias for the domain to set up an A record. Also, they will redirect some domain name to other ones. With this record types you can point multiple hostnames to the A record Address: For example ftlp.yourdomainname.com, mail.yourdomainname.com are CNAME.
MX- Mail Exchange
Mail Exchange records specify the mail server that is responsible for accepting the email messages for your domain name. For Example for routing all the emails sent to emailaddress@yourdomain.com, to your mail servers you should specify your Mail Exchange record. You can also determine the count for trying the server for say”10“, “20” or any other no as the MX record priority. This record helps in determining the order in which to try with the servers. The server with the lowest MX priority is tried first and if a server fails to respond the server with next lowest priority is tried and so on.
