Abstract

The invention discloses a domain name request processing method and device. Wherein, the method includes: the domain name server obtains a domain name access request, wherein the domain name access request is used to access a predetermined domain name; the domain name server judges whether the predetermined domain name is pre-configured in the blacklist; if the judgment result is yes, the domain name server then accesses the domain name The source of the request returns the pre-configured predetermined network address; if the judgment result is no, the domain name server returns to the source the network address corresponding to the resolved predetermined domain name, where the page pointed to by the predetermined network address includes a message indicating that the predetermined domain name is restricted from access. information. The invention solves the technical problem that the existing domain name server directly resolves all domain name requests, resulting in low network security.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a domain name request processing method and device. Background technique [0002] Every host on the Internet has a unique network address (ie IP address) to distinguish it from other computers on the network. Since the IP address is a digital identifier, it is represented by a binary number. Each IP address is 32 bits long and consists of 4 numbers less than 256. It is inconvenient for users to memorize and write. A symbolization has appeared on the basis of the IP address. Each symbolic address corresponds to a specific IP address, and this character address corresponding to an IP address on the network is called a domain name. A domain name is an important identification of an online unit and individual on the Internet, which is convenient for others to identify and retrieve, and better realize resource sharing on the Internet. [0003] A domain name server (Domain Name Server, DN...
