US Classification:
709201, 709245, 707 10, 707201, 714 4
Abstract:
A technique is performed by a high availability main primary DNS name server. The technique involves receiving a DNS update sent from a DNS client to the main primary DNS name server and directly modifying a main DNS record based on the DNS update. The technique further involves directing a backup primary DNS name server to modify a backup DNS record based on the DNS update while both the main primary DNS name server and the backup primary DNS name server (i) are configured to distribute DNS information to secondary DNS name servers and DNS clients and (ii) are in ongoing communication with each other, the backup primary DNS name server being configured to receive DNS updates sent from the DNS clients to the backup primary DNS name server and modify backup DNS records based on the DNS updates in response to a loss of communication between the main primary DNS name server and the backup primary DNS name server.

Abstract:
A technique is performed within a DNS server to respond to a DNS message. The technique includes receiving the DNS message from a requesting device (e. g. , a DHCP server), and generating a search result based on a search of a portion of the DNS message for a request to delete a specific record (i. e. , a specific, predefined record which is not expected to exist in the DNS). The technique further includes selectively providing and not providing current state information (or other information) to the requesting device depending on whether the search result indicates that the request to delete the specific record resides within the portion of the DNS message. Such operation allows for augmented operation with augmented DNS clients, as well as non-augmented operation with legacy equipment.
