IP Address Management

Address plans, DHCP leases, DNS records, and security controls are closely connected parts of a working network. IP Address Management, second edition, explains how to manage those pieces together—from core IP addressing concepts to the operational workflows and newer network environments that make IPAM increasingly important.

From IP fundamentals to coordinated IPAM

Dooley and Rooney begin with the essentials: how IP networks communicate, how IPv4 and IPv6 addresses are structured and assigned, and how DNS helps people and systems navigate network services. The book also covers DHCP and address-allocation approaches, giving readers a foundation for understanding the services that sit alongside an IP address plan.

Make network management a connected practice

Rather than treating address inventory, service configuration, and troubleshooting as isolated chores, the book examines IPAM as part of broader network management. Its operational coverage includes allocation and assignment, address changes, monitoring, inventory assurance, capacity planning, auditing, reporting, and security management.

IPv6, cloud, and the expanding network

Dedicated sections explore IPv6 deployment and coexistence with IPv4, including dual-stack, tunneling, and translation approaches. The discussion also extends to IPAM for Internet of Things environments and cloud networks, with attention to automation, workflows, and multi-cloud operations.

Security across DHCP, DNS, and network access

Security coverage addresses risks to DHCP and DNS services, ways to mitigate attacks, DNSSEC, encrypted DNS, and network-access controls. These topics show how IPAM-related services intersect with the wider effort to protect network infrastructure.

A working reference for networking professionals

The book’s five-part structure moves from introductory concepts through IPAM mechanics, security, and practical deployment before finishing with reference chapters on IP addressing, DHCP, and DNS. That progression gives readers both a path through the subject and detailed material to consult when specific protocol questions arise.

Written for network engineers, managers, planners, architects, and security professionals, this edition also suits students studying networking, information technology, or computer security. It offers a broad, organized view of the protocols, processes, and planning decisions behind effective IP address management.
