Why Is a Message Indicating Conflict with an Existing Record Set Displayed When I Add a Record Set?

If message "This record set is in conflict with an existing one" is displayed, the record set you are trying to add conflicts with or is the same as an existing record set.

Table 1 lists the rules.

**Table 1** Restrictions between record types
	CNAME	A	AAAA	MX	TXT	PTR	SRV
CNAME	Repeat	Conflict	Conflict	Conflict	Conflict	Conflict	Conflict
A	Conflict	Repeat	No limit	No limit	No limit	No limit	No limit
AAAA	Conflict	No limit	Repeat	No limit	No limit	No limit	No limit
MX	Conflict	No limit	No limit	Repeat	No limit	No limit	No limit
TXT	Conflict	No limit	No limit	No limit	Repeat	No limit	No limit
PTR	Conflict	No limit	No limit	No limit	No limit	Repeat	No limit
SRV	Conflict	No limit	No limit	No limit	No limit	No limit	Repeat

The rules are as follows:

Repeat: A record set of the same type already exists, and record sets of the same type can be added.
Conflict: The two types of record sets cannot have the same resolution line.
No limit: The two types of record sets can coexist.

If the message is displayed, perform the following operations:

Delete the existing record set that conflicts with the record set that you want to add, and then add the record set back.

Deleting a record set may cause domain name resolution to fail.
Set a different name for the record set.
