This feature includes enhancements to Junos OS domain name system (DNS) support, which allows you to use domain names as well as IP addresses to identify locations. Enhancements include:

DNS proxy: The device proxies hostname resolution requests on behalf of the clients behind the SRX firewall.
DNS proxy with split DNS: You can configure your proxy server to split the DNS query based on both the interface and the domain name. You can also configure a set of name servers and associate them with a given domain name.
Dynamic DNS (DDNS) client: Servers protected by the device remain accessible despite dynamic IP address changes.
