Academia has recently proposed new naming systems based on flat Distributed Hash Table (DHT). These naming systems are designed to overcome defects-such as lack of support for data migration and replication-in the Domain Name System (DNS). DHT naming systems have long resolution delay and are not suitable for practical application. This paper introduces two new naming systems that have the advantages of both DNS and DHT systems. The first is a three-layer system based on one-hop DHT and is suitable for small-scale application. The second adopts a hybrid DHT structure, can be implemented in different domains, and can be applied globally. Theoretical analyses demonstrate that these two systems are feasible for practical use.
