and the server query module is used for inputting the domain name to be accessed into a domain name resolution server to query the network address if the network address corresponding to the domain name is not queried in the block chain system, and returning the obtained query result to the client so as to finish the intelligent resolution of the domain name.
7. The intelligent domain name resolution device according to claim 6, wherein the inputting the domain name into a pre-constructed blockchain system for querying a network address comprises:
storing the network address in the cache management module;
recording the domain name on a block chain to obtain a legal domain name, and storing the legal domain name in a cache management module for storing the network address in a block form;
and utilizing a tracking management module to inquire the network address of the legal domain name in the cache management module.
8. The intelligent domain name resolution device according to claim 7, wherein the utilizing trace management module to perform network address query on the legal domain name in the cache management module includes:
obtaining the hash value of the legal domain name in the cache management module, and constructing a dictionary tree according to the hash value of the legal domain name;
traversing and querying the established dictionary tree by using a Tracker instruction to obtain a leaf node corresponding to the legal domain name, wherein the leaf node is a hash pointer of a legal domain name address;
