I’m asking for Cloudflare support on SRV record with entry of
0 0 0 .
Currently, Cloudflare requires port number to be greater then or equal to
1 and setting the target to
. automatically changes it to the current domain used.
But per RFC 2052,
The port on this target host of this service. The range is 0-65535. This is often as specified in Assigned Numbers but need not be.
As for MX, the domain name of the target host. There MUST be one or more A records for this name. Implementors are urged, but not required, to return the A record(s) in the Additional Data section. Name compression is to be used for this field.
A Target of “.” means that the service is decidedly not available at this domain.
So, the RFC said that the range of
0 and the target of
. is a valid entry. Could Cloudflare support these entry?
