If we cannot reach the destination IP address and cannot identify a route to the next-hop at any point in the network using the TCP/IP protocol suite, we will utilise the PING and TRACEROUTE tools to diagnose the cause and LOCATION of the problem.

The following are some general steps to troubleshoot IP-related network issues:

• To begin, identify the pair of devices between the source and destination hosts that are experiencing CONNECTIVITY issues.
• The failure could be due to a physical connectivity issue once you've located the devices using the tools. As a result, EXAMINE all of the physical connections along the path.
• If you WORK in a LAN network, there may be a problem with the LAN connectivity as well. As a result, double-check your LAN connections. The local port may be BROKEN or unavailable, preventing the source from communicating with the destination IP.
• A router connectivity issue when travelling through numerous channels to reach the destination could be one of the causes of the error. As a result, verify that the router is appropriately defined at each intermediate hop.
• Examine the configuration options.
