Introduction to DHCP
Dynamic Host Configuration Protocol (DHCP) plays a foundational role in modern IP networks by automating the assignment of IP addresses and essential network parameters to client devices. In environments with a high volume of connected devices, from broadband CPEs to enterprise endpoints, from DOCSIS to FTTx, reliable DHCP operations ensure seamless connectivity, reduce manual intervention, and improve scalability.
What is DHCP?
DHCP is a network protocol used to dynamically assign IP addresses and configuration parameters (like default gateway, DNS servers, and subnet mask) to devices on an IP network. This eliminates the need for manual configuration of each device, streamlining network administration and reducing human error.
At its core, DHCP is a protocol that automates the assignment of network configuration information, allowing devices (DHCP clients) to communicate within a network.
At Axiros, our expertise is focused on robust, scalable, and highly flexible DHCP solutions. Whether you're managing thousands or millions of subscribers, running hybrid multi-vendor environments, Axiros AX DHCP offers a flexible and automated way to achieve it without forgetting centralised control and observability. Offering also interfaces for OSS/BSS systems integration, allowing full automation in network IP management and provisioning.

How DHCP Works?
The DHCP process follows a straightforward, four-phase sequence: Discovery, Offer, Request, and Acknowledgment (commonly known as DORA). When a device connects to the network, it sends a DHCP Discover message. The DHCP server responds with an IP Offer, the client sends a Request for that IP, and the server Acknowledges it — thereby assigning the IP and completing the lease negotiation.
Axiros extends this flow with policy-driven address management, high-availability clusters, and advanced lease analytics to support both broadband service providers and enterprise IT environments.

What Challenges Does DHCP Solve?
In complex network environments, manual IP assignment is not just inefficient — it’s unsustainable. DHCP addresses multiple pain points:
Reduces IP conflicts and configuration errors
Supports rapid device onboarding
Enables dynamic network scaling
Improves operational efficiency by automating repetitive tasks
Enhances end-user experience with faster, more reliable connectivity
With Axiros, DHCP becomes a strategic asset that supports service agility and infrastructure modernization.
Implementation of DHCP in Network Infrastructures
Axiros’ AX DHCP is built to support diverse deployment scenarios — from residential broadband and fiber-to-the-home (FTTH) to corporate enterprise and mobile backhaul. It can operate as:
A primary DHCP server, managing IP lifecycle end-to-end
A DHCP relay or proxy, interacting with distributed environments
A policy enforcement point, integrating with subscriber management and AAA systems
The system is compatible with various access technologies, including DOCSIS, DSL, GPON, and LTE/5G, and is designed to meet regulatory compliance and performance benchmarks demanded by telecom operators.
