Abstract

The embodiment of the invention provides a network protocol IP address obtaining method and communication equipment, relates to the field of communication, and can solve a problem in the prior art that the switching speed of an IP address is slow because there is blocking operation in the call of an API function for the releasing of the IP address. The specific scheme of the invention that a physical card is controlled to be disconnected with a DHCP (Dynamic host configuration protocol) server when the communication equipment determines that the physical card needs to switch a current first IP address; the communication equipment controls the physical card to be connected with the DHCP server, so as to trigger the physical card and the DHCP server for DHCP message interaction, and obtain a to-be-switched second IP address of the physical card. According to the embodiment of the invention, the method is used by the communication equipment to obtain the IP address.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method for acquiring a network protocol IP address and a communication device. Background technique [0002] Dynamic Host Configuration Protocol (DynamicHostConfigurationProtocol, DHCP) is a LAN network protocol, which provides a mechanism for dynamically assigning Internet Protocol (InternetProtocol, IP) addresses and configuration parameters. The communication device dynamically assigns an IP address. On the Windows operating system platform, in the process of dynamically assigning an IP address through DHCP, it is necessary to send a DHCP message to the DHCP server to apply for or release an IP address by calling an application programming interface (Application Programming Interface, API) function provided by the Windows operating system. On the Windows operating system platform, if you want to switch the IP address through DHCP, you need to call the API function to send a DHC...
