Abstract
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.
