Network Utilities - ping

The ping utility sends a series of packet from a source computer (in this case www.e-insights.com) to a target machine (entered in the box below) and reports on the time required for the packet to transit the network from source to target.

Additionally, packet loss is tracked and reported. This utility is frequently used to check if a target machine is operating and if it has good network connectivity.

Network Utilities - nslookup

The nslookup (Name Service lookup)utility queries the Domain Name Server hierarchy and determines the IP address of a specified machine name.

Network Utilities - traceroute

The traceroute utility sends a series of packets from a source computer (in this case www.e-insights.com) to a target machine (entered in the box below) and attempts to identify all intermediate routing points along the way. The name of the intermediate points is identified and the time taken to get a response from each intermediate point is measured.

Traceroute is very helpful in identifying network routing problems.
