Adding CNAME for the root domain issue

[Daniel Dawalibi]

Hello John

The below is not working on our BIND version BIND 9.10.0-P2 unless it is working on other version

Domain.com.  CNAME  x.y.com.
www     CNAME x.y.com.

Errors returned when adding these records:

general: dns_master_load: ourweddingaccount.com.db.inter:13: ourweddingaccount.com: CNAME and other data


If we proceed with the below work around by replacing the CNAME with A record, It will resolve but our setup requires a CNAME record.

Domain.com.  A  IPaddress
www     CNAME x.y.com.




Regards
Daniel

Assuming you mean this (notice the dots):

 Domain.com.  CNAME  x.y.com.
 www     CNAME x.y.com.

it should work.  Some people believe that you can't have other records at names below a name with a CNAME, but they are mistaken.

On the other hand, this will not work.

  domain.com. CNAME x.y.com.
  domain.com. MX 10 server.somewhere

To make this work, you need Stephane's hack of copying the A and AAAA records.

R's,
John
