Prisma Access allows you to specify DNS servers to resolve both domains that are internal to your organization and external domains. Do this to provide access to services on your corporate network—like LDAP and DNS servers—especially if you plan to set up service connections to provide access to these type of resources at HQ or in data centers. Prisma Access supports DNS resolution for mobile users- Global Protect and remote networks deployments. DNS queries for domains in the Internal Domain List are sent to your local DNS servers to ensure that resources are available to Prisma Access remote network users and mobile users.

For example, if you want a DNS lookup for your corporate domain to go exclusively to the corporate DNS server, specify the corporate domain and the corporate DNS servers here.
