Abstract: The resolving process of current DNS is analyzed. With the problems of heavy line traffic and security,an improved scheme on resolving domain name is proposed. The scheme improves the resolving mechanism and enhances the security of current DNS. It can also reduce query delay and line traffic, improve responsive speed and system security, and realize relatively rapid and secure domain name resolution.
