Abstract: Domain name service (DNS) plays an important role in the Internet. The combination of ENUM technology and DNS has been widely used in the three networks convergence, and the BIND system accounts for a high rate in the DNS. This paper compares the difference between the RFC and the BIND system on the longest matching rule. By comparing the results of the two types of DNS, a dual search strategy is proposed to modify the BIND system, so that the DNS conforms to the standard RFC. This can provide ideas for more standard service customization processing, and deploy an application in the real network.

Key words: domain name system (DNS), the longest matching, modification strategy, customization service
