Abstract
Dynamic Host Configuration Protocol (DHCP) reservations are essential for ensuring consistent Internet Protocol (IP) addressing for critical devices, but conventional IP assignment approaches rely on manual mappings that are complex, error-prone, and difficult to scale. Moreover, conventional IP assignment approaches introduce management overhead, risk of IP conflicts, and lack a mechanism for dynamically and securely assigning fixed IP addresses to DHCP clients. To address these limitations, the techniques presented herein implement a dynamic, secure, and centralized DHCP reservation solution using a Network Access Control (NAC) platform. The techniques presented herein enhance the Remote Authentication Dial-In User Service (RADIUS) protocol to carry DHCP fixed-IP policy and extend DHCP signaling to indicate client intent for fixed IP assignment, thereby enabling automated IP allocation, eliminating manual configuration, reducing errors, and performing scaling without requiring changes to endpoint devices.
