CNAME chasing refers to the lookup performed by a name server when the name server needs to resolve a dependent record as part of processing a CNAME record. CNAME chasing applies only to private Domain Name System (DNS) resources; CNAME records in public managed zones are always chased by the user's resolver.
The following table summarizes CNAME chasing support in Cloud DNS. The left column represents the fixed location of the CNAME. The rows represent the corresponding zone boundaries where the A (or AAAA) record being chased exists.
In the following table, = Supported, and = Not supported.
|Location of CNAME record||Cloud DNS private zone||Cloud DNS public zone||Internet zone (not Cloud DNS)|
|Cloud DNS private zone|
|Cloud DNS public zone|
|Internet zone (not Cloud DNS)|
