There are three solutions for IPv6 recursive DNS server address configuration in 3G networks. This paper describes the attributes of these approaches: Router Advertisement(RA) approach,DHCPv6 approach and well-known any cast addresses approach.

• 说明了3G网络中IPv6递归DNS服务器地址配置的三种方法:路由器通告(RA)方案,DHCPv6方案,递归域名系统(DNS)服务器的公认任播地址方案,详细地说明了三种解决方案的操作特点。
