METHOD FOR PROTECTING COMPUTER NETWORKS Russian patent published in 2023 - IPC G06F21/50 H04L41/806 H04L61/5014 

FIELD: computer engineering.

SUBSTANCE: invention is aimed to increase the degree of protection of computer networks, as well as to reduce the resource intensity of protection and increase the availability of authorized network devices. It is achieved by providing the ability to change the IP addresses of network devices within several subnets without breaking critical network connections established between them, and also by reducing the degree of centralization of the process of changing IP addresses by ensuring localization of their change by network devices within a pre-defined set distributed by the DHCP server.

EFFECT: increasing the degree of protection of computer networks, as well as reducing the resource intensity of protection and increasing the availability of authorized network devices.
