Abstract
A plurality of separate DNS zones are combined to form a composite DNS zone. The composite DNS zone is viewed as a single DNS zone by other elements on the network. Each of the separate DNS zones becomes a component DNS zone within the composite DNS zone but can still be separately owned and managed using standard DNS protocols. As such, the composite DNS zone provides a transparent method of combining DNS data owned by separate parties into a single location that can be searched using a DNS request of the prior art.DNS requests directed to the composite DNS zone may result in a plurality of answer candidates. Some embodiments include algorithms for searching the composite DNS zone and assembling a DNS answer from the plurality of answer candidates. The composite DNS zone may include telephonic DNS data according to the ENUM standard.
