Ping could be disabled on the remote machine.
Telnet cannot be used as a reliable method, because we have
to know the services running on the machine to telnet to
that port.
nmap would be a reliable method, but normal nmap checks are
disabled in the network level, so it would be good to run
nmap in stealth mode.
nmap -sS <IP Addr>
