  • Using domain name server queries for managing access control lists
    Patent number: 10079799
    Abstract: In one embodiment, a caching resolver receives a name server query from an end device for an Internet Protocol (IP) address for a hostname, and determines whether the hostname requested is in an access control list (ACL). In response to the hostname being in the ACL, the caching resolver examines a received response to the name server query for the hostname, wherein the received response contains a particular IP address for the hostname, and adds the particular IP address for the hostname to the ACL. In one embodiment, the ACL is local to the caching resolver, while in another embodiment, adding the particular IP address for the hostname to the ACL comprises sending a message to a remote ACL-maintaining device that maintains the ACL.
