一种基于域名错误的DNS重定向协议

A DNS Redirect Protocol for Domain Name Errors

域名系统(DNS)重定向是为互联网服务提供商(ISP)和DNS应用服务提供商(ASP)的用户实现增值服务的有效功能。定义以不同于错误查询域名的按相关性排序的推荐域名列表作为错误描述。提出重定向服务器的两个转交过程,以利于正确及时地找到推荐域名。此外,提出使用延长资源记录的请求处理算法。定义重定向报文结构以在DNS协议内容纳重定向IP地址信息。

Domain name system （DNS） redirect is expected to be the emerging functionality to perform a value added services for users by the Internet Service Providers （ISP） and the DNS Application Service Providers （ASP）. This paper specifies the error description as the list of suggested domain names other than the original one, which are sorted by their relevance. Two handover processes for the redirected server is proposed, which can facilitate finding the suggested domain names both correctly and timely. Besides, the request handling algorithm is proposed using the prolonged resource records. The message structure of the redirect is defined to accommodate the redirect IP information in the DNS protocol.
