A server on the network is unreachable. What is the best method to verify connectivity between your computer and the remote server?

`lookup` (or `nslookup`/`dig`) is used for DNS resolution, not for verifying network reachability to a host.

`find` is a Linux command used for locating files and directories, unrelated to network connectivity.

The `ping` command sends Internet Control Message Protocol (ICMP) echo request packets to a target host and listens for ICMP echo reply packets. A successful reply indicates basic network connectivity and reachability between your computer and the remote server, making it the primary tool for initial connectivity checks.

`netstat` displays network connections, routing tables, and interface statistics, which is useful for analyzing network state, but not for actively testing reachability to a remote server.
