Abstract
Dynamic resolution of Fully Qualified Domain Name (FQDN) address objects in policy definitions is provided. In some embodiments, dynamic resolution of Fully Qualified Domain Name (FQDN) address objects in policy definitions includes receiving a network policy that includes a domain name (e.g., the network policy can include a network security rule that is based on the domain name); and periodically updating Internet Protocol (IP) address information associated with the domain name by performing a Domain Name Server (DNS) query. In some embodiments, dynamic resolution of Fully Qualified Domain Name (FQDN) address objects in policy definitions includes dynamically performing a first local Domain Name Server (DNS) lookup for a first VSYS using a first DNS server on a first domain name for implementing a network policy based on the first domain name; dynamically performing a second local DNS lookup for a second VSYS using a second DNS server on the first domain name for implementing the network policy based on the first domain name; in which the network policy includes a network security rule that is based on the first domain name, and the network policy includes a network security rule that is based on the second domain name.
