Best IP Management and Scanner tools


OpUtils is a switch port and IP address management software that helps engineers diagnose, troubleshoot, and monitor IT resources efficiently. It scans IPv6 and IPv4 subnets to identify the utilized and available IP addresses.

OpUtils also scans the switches available in your network, maps devices to switch ports, and views details like the users, locations, etc. This will help identify device intrusions and acts as a barrier to their access.

It allows you to track your network’s bandwidth usage and create bandwidth utilization reports for many parameters. It also schedules CISCO config file backups for downloading or uploading and compares other versions of the running and startup configuration files.

Using LAN tools, you can automatically or manually boot up idle machines present in your network. You can generate a graphical representation of SNMP IP nodes with the help of SNMP tools by viewing the snapshot of MIBs (Management Information Base) and query SNMP (Simple Network Management Protocol) devices.

To get this snapshot, you need to search the subnet for getting particulars of CISCO devices, and after that, you can collect some details like IOS details, flash memory, device snapshot, etc. It also scans TCP ports and SNMP devices and restores details of IP address, system, and more related to the MIB OID (Object Identifier).

You can also have access to manage, inspect, and resolve your MAC addresses, IP addresses, and DNS names with monitoring tools like MAC addresses and a DNS resolver. It will alert you on network issues that require your attention immediately by monitoring the servers in your network.
