The 7 Best IP Address Manager Tools

Managing IP addresses can be a daunting task. IP addresses are fundamental components of contemporary networks and for their optimal operation, a certain level of organization is required.

The goal of IP address management is to maintain an orderly arrangement of IP addresses, ensure there are no duplicates, and guarantee a constant supply of IP addresses for new devices connecting to the network. While this may seem complex, there are tools available to simplify the process. Today, we will explore some of the best IP address manager tools, including SolarWinds IP Address Manager, ManageEngine OpUtils IP Address Manager, Infoblox IPAM & DHCP, and Blue Cat Address Manager.

Firstly, let’s delve into the concept of IP addresses. We will examine what they are and how they function. Despite seeming intricate, the concept is quite straightforward. Next, we will introduce DNS (Domain Name Service), a technology that simplifies the use of IP addresses for us. It’s worth noting that IP addressing and DNS are so closely intertwined that most IP address manager tools handle both.

Following this, we will delve into IP address management, exploring its definition and what it involves. As most IP address manager tools aim to automate the management of IP addresses, we will discuss this aspect next. Lastly, before we review some of the best IP address manager tools, we will briefly touch on DHCP (Dynamic Host Configuration Protocol), another technology closely related to IP addressing and its management.

IP Addresses – The What And The How

IP addresses are used to uniquely identify each and every device connected to an IP network. This IP network could be your home WiFi network, the network at your place of work or the Internet. Although each of these may be interconnected, they are individual networks. An IP address is, in many ways, similar to a street address. Its primary purpose is to help in transporting data from an origin to a destination.

IP addresses are huge 32-bit long binary numbers. Obviously, it could be impractical and error-prone to write them in binary or even using their decimal equivalent. They are, therefore, split into four chunks of 8 bits each which we usually represent as a suite of 4 decimal numbers between 0 and 255 separated by dots. For instance, the IP address 11000000101010000000000000000001 becomes, a much easier to read format.

An IP address consists of two parts, the host and the network or, more precisely, the sub-network. This has to do with IP routing which is used when sending data to an IP address on a different network—typically in a different location. Which part of an IP address represents the host and which part represents the network is the most complicated aspect of IP addressing. It is complicated because it left to network designers and administrators to determine it. The boundary between the subnet, as it is often called, and the host can be at any bit within the address’ thirty-two.

Communicating what part is subnet and what part is host is another complicated matter. In the beginning of IP networking, we used what was called classful addressing where certain predefined address ranges had predefined boundaries. For instance, any address starting with 192.168 had 24 bits for the subnet and 8 bits for the host. That worked well but it was not flexible enough so classless addressing started to be used where the boundary can be anywhere.

In order to indicate what part of an IP address is the subnet and what part is the host, two different notation schemes have emerged. The first way is to specify a subnet mask along with the IP address. This is another dotted-decimal number in which each 1 indicates a subnet position and each zero indicate a host position. For example, the subnet mask indicates 24 bits for the network and 8 for the host. Another notation which is often referred to as classless addressing requires adding a forward slash followed by the number of subnet bits to an IP address. For example, one would write /24.

DNS To The Rescue

IP addresses are great for computers to use to locate each other and exchange data but they are not really user-friendly and they tend to be hard to remember. At the beginning of IP networking, each computer had a “hosts” file where the correspondence between IP addresses and hostnames were listed. That enabled a user who wanted to connect to a remote computer to use its hostname rather than its IP address, provided that there was a corresponding entry in his computer’s hosts file.

The Domain Name Service was later created to enable a distributed database of hostname to IP address correspondences. Instead of looking up an address in its local “hosts” file, a computer would query a DNS server which, through a rather simple yet elaborate process, would eventually—within a matter of a few tenths of a second—return the corresponding IP address. IP addresses and DNS work together at enabling computers and their users to easily locate remote systems.

About Managing IP Addresses

Managing IP addresses is among the most important tasks of network administrators. It mainly serves two purposes: making sure each device is assigned an IP address and making sure no IP addresses are duplicated within a network. Back when networks used to be small(er), manually managing IP addresses was the way to go. Administrators typically kept a text file or Excel spreadsheet where each assigned IP address was documented. As networks grew bigger, this method started to exhibit serious shortcomings. For starters, how can you assure that each and every change to the network will be reflected in the documentation? Also, how do you assure or verify that the IP addresses that are configured on devices are those that were assigned? And how do you make sure that any change in IP address assignment is reflected it the local DNS server?

Automating The Process

Automation is the key to avoid many of the issues we just mentioned. This is also why IP Address Management, or IPAM, tools were first created. These tools vary greatly in their functionality with the most basic simply being glorified versions of the text files or spreadsheets of the past while others are complete automated systems with active connections to other related systems—such as DNS and DHCP—to offer the most robust of solutions.

A Word About DHCP

The Dynamic Host Configuration Protocol, or DHCP, is also closely related to IP address management. As its name suggests, it is used to automatically configure hosts with the proper IP address and other network interface settings. Computers using the protocol will contact a DHCP server upon startup to get their IP address, subnet mask, default gateway, DNS server(s), and several more configuration parameters in a dynamic fashion. Many IP address management tools either include a DHCP server or can communicate with an existing DHCP server, ensuring that the information they contain is what is actually configured on the networked computers.

The Best IP Address Manager Tools

We’ve searched the Internet for the best IP address manager tools we could find. Some of the products we found include built-in DNS and DHCP functionality.
