DNS resolution method and system based on coding and decoding technology

The invention discloses a DNS resolution method based on a coding and decoding technology, which comprises the following steps: an HTTP coding scheduling center acquiring an IP address of a node server from an equipment center, precoding the IP address and storing the IP address in a DNS resolution mapping table; receiving an HTTP request sent by the terminal to an HTTP coding scheduling center, and selecting an IP coding string domain name corresponding to the HTTP request from a DNS resolution mapping table according to a set IP address-based scheduling strategy; returning coding informationcarrying an HTTP state code of 301/302 and a Location header carrying an IP coding string domain name to the terminal; and the terminal requesting to decode the decoding DNS resolution system according to the encoding information, and accessing the corresponding IP address according to the decoding result fed back by the decoding DNS resolution system. According to the method, the IP code stringis used, the IP of the nod
