Records are organized into various types according to the data they contain. The most common type is an 'A' record, which maps a name to an IPv4 address. Another common type is an 'MX' record, which maps a name to a mail server. Sometimes you need to create more than one DNS record with a given name and type. For example, suppose the 'www. The website requires two different A records, one for each IP address. Here is an example of a record set:. A record set also known as a resource record set is the collection of DNS records in a zone that have the same name and are of the same type.

Most record sets contain a single record. However, examples like the one above, in which a record set contains more than one record, are not uncommon. For example, suppose you have already created an A record 'www' in the zone 'contoso.

To create the second record you would add that record to the existing record set, rather than create an additional record set. The DNS standards don't permit multiple records with the same name for these types, therefore these record sets can only contain a single record. The time to live, or TTL, specifies how long each record is cached by clients before being requeried.

In the above example, the TTL is seconds or 1 hour. In Azure DNS, the TTL gets specified for the record set, not for each record, so the same value is used for all records within that record set. You can specify any TTL value between 1 and 2,,, seconds.

Azure DNS supports wildcard records. Wildcard records get returned in response to any query with a matching name, unless there's a closer match from a non-wildcard record set.

CAA records allow domain owners to specify which Certificate Authorities CAs are authorized to issue certificates for their domain. This record allows CAs to avoid mis-issuing certificates in some circumstances. CAA records have three properties:. CNAME record sets can't coexist with other record sets with the same name. For example, you can't create a CNAME record set with the relative name 'www' and an A record with the relative name 'www' at the same time.
