11 Best IP Scanner Tools for Network Management

You need IP Scanner tools to manage your network as a network administrator. These programs allow you to control your network and its connected devices.

In this article, we'll review the best IP scanner tools that let you manage devices through their IP addresses. We'll also list network scanning tools that offer many features, like scanning the network for vulnerabilities in addition to network IP address scanning.

Let's get started.

What are IP scanners and network scanning tools used for?

IP scanner tools primarily analyze the network to discover IP addresses. It also offers additional relevant information associated with the devices associated with those IP addresses. These IP scanners utilize ICMP ping sweeps to find IP ranges. It also creates SNMP scans to create map network topology. In short, an IP scanner lets you capture devices' IP, DNS information, and Dynamic Host Configuration Protocol (DHCP) information.

On the other hand, the network scanners give information such as hostname, vendor type, and MAC address. Network administrators can also use network scanners to troubleshoot the network quickly.

Benefits of using IP scanner software

IP scanner software offers IP management with proper IP address usage information. Moreover, they make the network administrators' work easy by automating IP scanning. This way, there is no need to do manual IP scanning; hence, you never have to suffer from error-prone data.

The key benefits include the following:

• Quick access to network information

• Easy discovery of IP addresses and subnets

• Automatic updates of network IP addresses.

• Scanning and managing IP subnets

• Get vital information for network organization and mapping

• Simplified monitoring with IP scanning support for IPv4 and IPv6 addresses

• Ensure IP allocation consistency through proper IPv4 and IPv6 scanning.

• Provide a centralized console to manage the network devices

• Get a full picture of IP resource usage, identifying key information such as mac address, network type, last scan time, asset details, system name, and even physical address.

• Improve network performance with proper space utilization and fragmentation using subnets.

• IP scanner software makes it easy to manage dynamic networks by IP scanning across multiple subnets and supernets in real-time

• Enables proper capacity planning while staying ahead of IP resource exhaustion

• Avoiding costly network issues with the IP scanner's proactive monitoring capability
