In a multi-core platform in which secondary processor cores do not have direct WAN connectivity, methods and apparatus are described that enable the secondary cores to provide DNS resolution services to their network applications or to attached client devices. In an exemplary embodiment, a primary processor core having direct WAN connectivity includes a DNS forwarder which shares with the platform's secondary processing cores DNS server IP address information acquired from a WAN-side DHCP server. Each secondary core implements a compatible DNS forwarder client to request DNS information from the primary core DNS forwarder, receive the information, and make it available to its operating system's DNS resolver module. Additionally, or alternatively, the primary core DNS forwarder may push updated DNS server information to each secondary core following a primary core DHCP client lease renewal. |
