With the continuous development of communication network technology, the application of IP addresses has also progressed tremendously. Currently, when using SIM cards for data communication, each SIM card needs to be assigned an IP address, and the IP address is a unique digital identifier for identifying network devices, so that communication and data exchange between communication devices can be performed. Where the IP address of the SIM card is typically temporary, which means that a different IP address may be assigned each time a connection is made to the network. The IP address of a SIM card may not only vary from card to card, but may also vary in different network environments. For example, different IP addresses may be assigned when using a SIM card for communication in different geographical locations or in different networks of mobile network operators. In the conventional technology, a Mysql database is generally used to perform an IP address allocation operation. Each time an IP address is allocated, it needs to check whether each IP address in the Mysql database is occupied, and if any IP address is not occupied, it can be allocated to a SIM card. However, since each IP address of the Mysql database needs to be checked at each allocation, the system allocation efficiency is low, and the problem of repeated allocation of the same IP address easily occurs.

In order to solve the above technical problems, the embodiments of the present application provide the following technical ideas: the inventor considers the shortcoming of the prior Mysql database that the related IP address allocation operation is carried out, and carries out static IP address sequence allocation, static released IP address allocation and specified IP address allocation for the SIM card or the equipment based on the Redis bitmap, so that the efficiency of allocating the IP address by the bitmap system is higher, and the problem of repeated allocation of the same IP address does not occur.
