TCP vs ICMP Ping
Traditional "ping" commands use the ICMP protocol. However, many modern firewalls and cloud hosting environments (like AWS or shared hosting) block ICMP packets to prevent discovery/DDoS attacks. Our tool uses **TCP Ping**, which measures the time taken to complete a handshake with a web server. This is often more useful for webmasters because it reflects the actual latency users experience when trying to access a website or API.
