Ping

Traceroute

DNS Lookup

Objective

Ping is a technique which is used to test if a host can be reached. It also measures the total trip time. Ping is useful if you want to troubleshoot the network connectivity or bandwidth.

Traceroute discovers the IP routes along which packets are forwarded. To do this, Traceroute sends IP packets to the different hops as well as the target host and back to the router. The Traceroute page allows the user to view each hop between the router and the target host as well as the round-trip time to each stop.

In a real time scenario, a traceroute can be used if you have some connectivity problems and need to find whether the packets are delivered to the destination or not. Traceroute can exactly point out where the packets are dropped if such a problem exists.

DNS Lookup is a technique when a device asks a DNS server for the IP address associated with a domain name. The DNS server then "look ups" the IP associated with that domain name.
