摘　　要：域名服务在Internet中具有重要作用,ENUM技术与域名解析结合在三网融合中被广泛应用,在域名服务领域BIND系统占比很高。对比RFC对最长匹配规则定义与BIND系统实现存在的差异,通过2类域名服务软件解析结果确认,提出双重检索的策略修正BIND系统,使得NAPTR记录的解析结果更符合标准RFC描述,为更多的标准服务定制化过程提供了思路,并在实网中部署了应用。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.
