DNSRecord Type

A record that is returned by the DNS server.

Remarks

When a Query method is performed by the DNS component, the DNS server returns one or more DNSRecords containing information about the domain you specified. This information is contained in the different fields of the record.

Each record may have multiple FieldNames and corresponding FieldValues. You may iterate through these by setting the FieldIndex field.

Fields

Domain
String

This field contains the domain name associated with the selected response record, at RecordIndex.

FieldCount
