BEST Network Diagnostic & Troubleshooting tools

Network diagnostic software is designed to help user and network administrators in scanning, diagnosing and identifying problems within a computer network.

It is a type of network management software that helps in finding network connectivity, performance and other related problems.

Network diagnostic software primarily helps in automating the process of network troubleshooting. Rather than the network administrator or a user manually looking for errors, it scans and searches along all known network ports, paths and interfaces to find network problems.

Some of the ways network diagnostic software can be used include:

  • Internet/network connectivity issues such as unplugged wires, misconfigured proxy and more
  • DNS analysis
  • Identify and troubleshoot IP-addressing-related errors

In addition to network troubleshooting, network diagnostic software provides insight into basic network availability and performance statistics. It can be part of a network management/network performance monitoring application. Moreover, it can be used to diagnose network issues on both general end-user and enterprise networks.

  1. SolarWinds :-is a tool that quickly analyzes and troubleshoots wireless network faults, performance, and availability issues remotely. This application provides you real-time alerts that help you to reduce network downtime.It helps you to find the root cause of the issue and determine whether it is in the application or network. SolarWinds is one of the best remote monitoring software to perform network analysis and evaluate critical paths.

8. Ping:-Ping is a Windows operating system utility that helps you to determine latency, round trip time, and network packet loss. It provides you network problem that needs to be addressed.

This command can also be used to check the network connection speed. Ping is the basic utility when you begin your troubleshooting process.

9. Traceroute:-Traceroute is a network troubleshooting command that enables you to know about network devices between one point to another. It gives you extra data like latency values and the hostname of the gadgets. This network troubleshooting tool can also help to identify routing issues when you have more than one network connectivity.

.Traceroute network troubleshooting command enables you to view the route and measure the delay of network packets. It will give you the details of hops between both the source and destination devices.

10. Ipconfig:-Ipconfig (Internet Protocol Configuration) is a utility that can report IPv4 and IPv6 addresses, default gateways, and subnets for all gateways on a computer.

This functionality can also be used to manage IP addresses assigned to PCs that are currently running. You can write commands without additional parameters to identify your current Internet protocol address.

11. Nslookup:-

Nslookup is a good utility for locating the IP associated with a domain name and checking to see that DNS resolution is working for a host.

When you enter into the browser, your computer queries the DNS server to find the IP attached to that hostname as shown in the following figure.

Nslookup helps you to find these queries and other Domain Name System servers as per your desire. This network testing tool helps you to test the DNS server for the client or your own ISP (Internet Service Provider).

12.Netstat:-Netstat is a utility that is helpful on hosts or servers that run their own firewalls like Apache or SQL servers. This network troubleshooting command is very helpful to know the people who are connected to your hosts with a port number.
