Abstract

The invention discloses a network-address-mapping method, device, and system. The network-address-mapping method comprises steps that a filter intercepts a domain name resolution request carrying a domain name to be resolved and required to be accessed; the filter detects whether the domain name to be resolved is stored in a domain name storage memory, wherein the filter is located in a terminal sending the domain name resolution request; if yes, the filter reads an IP address corresponding to the domain name to be resolved from the domain name storage memory; and if not, the filter forwards the domain name resolution request to domain name resolution server. The method, the device and the system solves a problem that network addresses cannot be dynamically mapped in the prior art and achieve an effect of dynamically mapping the network addresses.

Description

technical field [0001] The present application relates to the field of the Internet, and in particular, to a network address mapping method, apparatus and system. Background technique [0002] Internet Protocol Address (Internet Protocol Address) is an international computer network address identifier, which is divided into two versions: IPv4 and IPv6. Among them, IPv4: consists of 32-bit binary numbers. For ease of use, it is often expressed in the form of XXX.XXX.XXX.XXX. Each group of XXX represents a decimal number less than or equal to 255. For example, an IP address for Wikimedia is 208.80.152.2. IPv4 addresses can be divided into five categories: A, B, C, D, and E, among which category E is a special reserved address. IP addresses are unique. At present, there are about 4.2 billion IP addresses that may be used by IP technology. Due to early coding and distribution problems, the coding of many areas is actually vacated or cannot be used. IPv6: The most significant ...
