CNAME instead of A Record for hostname in Sharepoint 2013 Farm

    Question

  • Hello

    i want to use a CNAME that point to an An Recorde to be able to change the DNS of the A record to point to read olny farm while patching the primary Farm.

    CNAME  abc.contoso.com points to  a.contoso.com

    CNAME  xyz.contoso.com points to  a.contoso.com

    A recorde a.contoso.com  192.168.10.10

    I can change a.contoso.com to 192.168.10.50

    all abc and xyz hostname changes to the new IP in one shoot.

    Is it recommended in SharePoint 2010/2013?

  • CName records won't accomplish what you are suggesting and they are NOT recommended for use in SharePoint other than when configuring Apps support.  A CName record lets you associate an alias with an existing A record so that both point to the same IP address.  You can't use them to change the IP address.

  • CNAME-records point back to an A record.

    So if you change the IP address of the A record, all your CNAME records pointed to that record automatically follow the new IP of the A record.
