ICMP Echo Ping
The -PE option performs an ICMP (Internet Control Message Protocol) echo ping on
the specified system.
Usage syntax: nmap -PE [target]
Performing an ICMP echo ping
The -PE option sends a standard ICMP ping to the target to see if it replies. This type of discovery works best on local networks where ICMP packets can be transmitted with few restrictions. Many internet hosts, however, are configured not respond to
ICMP packets for security reasons.
Note
The -PE option is automatically implied if no other ping options are specified.
