Abstract
A client process may identify a local DNS server and may change a DHCP-supplied DNS setting to the local DNS server when the local DNS server is present. The client process may periodically monitor the local DNS server and, if the local DNS server is not present, the client process may revert the DNS setting to the originally supplied DHCP DNS setting. The client process may actively monitor the local DNS server by initiating communication with the local DNS server, or may passively monitor by listening for activity by the local DNS server.
