DOMAIN NAME COLLABORATION SERVICE USING DOMAIN NAME DEPENDENCY SERVER

摘要

A domain name dependency server (DDS) stores known relationships between domain names. In response to a domain relationship query from a local DNS server for a given domain name, the DDS supplies the domain names that are related to the given domain name. This reduces or eliminates serial requests for the related domain names from the local DNS server, reducing overall DNS lookup latency for the requested service. The DDS can be shared among multiple local DNS servers, and can be updated dynamically or manually to enhance the accuracy of its stored domain name relationships.

1. A method comprising:
at a local Domain Name Service (DNS) server, providing a first DNS query for a first domain name to a network for provision to a domain-name dependency server (DDS); in response to providing the first DNS query to the network, receiving from the DDS a first set of domain names related to the first domain name and storing the first set of domain names at a cache of the local DNS server; and generating a set of DNS queries at the local DNS server to identify addresses for the first set of domain names.
