If a tester is attempting to ping a target that exists but receives no response or a response that states the destination is unreachable, ICMP may be disabled and the network may be using TCP. Which o

Traceroute primarily relies on ICMP (or UDP) to map network paths, so it would likely fail if ICMP is disabled.

Hping (specifically hping3) is a powerful command-line network scanner and packet crafting tool that can send custom TCP packets, including SYN requests to specific ports, to elicit a response from a host when ICMP is blocked.

While 'TCP ping' describes the concept, it's not a specific tool or command; `hping` is a common tool used to perform such a function.

Broadcast ping sends ICMP echo requests to all hosts on a local network segment, which would not work if ICMP is disabled.
