ICMP Ping & Latency FAQ & Guide
What is a Ping test?
A Ping is a basic network administration utility used to test the reachability of a host (IP address or domain name) on an IP network. It measures the round-trip time for packets sent from the host to a destination computer and back.
What is an ICMP packet?
Ping uses Internet Control Message Protocol (ICMP) Echo Request and Echo Reply packets to perform its validation. It does not use TCP or UDP ports, making it a pure layer-3 network diagnostics check.
What causes high network latency (slow ping times)?
Network latency is influenced by geographic distance, number of network hops (routers) along the path, cable types (fiber optic, copper, or wireless satellite), network congestion, or slow server response processing.
What is packet loss and why does it happen?
Packet loss occurs when some of the ICMP request or reply packets fail to reach their destination. This is usually caused by physical link damage, loose wiring, overloaded router queues, wireless interference, or strict server firewalls dropping ICMP packets to prevent ping attacks.
