CNAME


By Marc Gaffan
Follow

A CNAME record or Canonical Name record is a type of resource record in the Domain Name System (DNS) that specifies that the domain name is an alias of another, canonical domain name. This helps when running multiple services (like an FTP and a webserver; each running on different ports) from a single IP address. Each service can then have its own entry in DNS (like ftp.example.com. and www.example.com.).

    So, it seems that Incapsula allows uses to add A records only? I'm interested in adding a CNAME, for instance to a OpenShift or Heroku instance. The IP address is ephemeral in those services. Do you have advice?
