Manage CNAME & DNAME records

This guide explains how to add or edit one or more type records CNAME and DNAME in the DNS area (of a domain name) managed on the Manager Infomaniak.

Preamble

• The type of recording CNAME allows the pointing of a subdomain to a website address.
  • This is the method generally used to operate the sub-domain www with your site, or to redirect a subdomain to a folder of the web server on which your website is hosted.
• The type of registration DNAME for "delegation nameIt is particularly useful when reorganizing domains or for smooth transitions from one part of your infrastructure to another, while preserving the hierarchical structure of sub-domains.
  • One DNAME creates an alias for an entire domain and all its subdomains.
• In contrast to the CNAME which applies to only one specific host name, the DNAME automatically redirects all subdomains. Example:
  • One DNAME for abc.site1.com Pointing towards site2.com will automatically link xyz.abc.site1.com to xyz.site2.com, new.login.abc.site1.com to new.login.site2.com, and so on.
• ⚠A record DNAME cannot be used at the root area of a domain (such as site1.com directly). It is usually used on a subdomain. If you want to redirect the main domain itself, you will need to use other types of records like a A, AAAA or CNAME (with certain restrictions for the latter).
