Configure DNS resource records

Last published : Sep 22, 2026
You configure resource records on the Citrix® ADC appliance when you configure the appliance as an ADNS server for a zone. You can also configure resource records on the appliance if the resource records belong to a zone for which the appliance is a DNS proxy server. On the appliance, you can configure the following record types:
  • Service records
  • AAAA records
  • Address records
  • Mail Exchange records
  • Name Server records
  • Canonical records
  • Pointer records
  • NAPTR records
  • Start of Authority records
  • Text records
  • Certificate Authority Authorization (CAA) records
The following table lists the record types that you can configure for a domain name record on the NetScaler appliance. For example, you can configure a maximum of 25 IP addresses for one record.
