What is ping and its protocol?

A ping (Packet Internet or Inter-Network Groper) is a basic Internet program that allows a user to test and verify if a particular destination IP address exists and can accept requests in computer network administration. Ping is a simple way to check for a response from a host.

What is ICMP and when would you use it?

Internet Control Message Protocol (ICMP) is used for reporting errors and performing network diagnostics. In the error reporting process, ICMP sends messages from the receiver to the sender when data does not come though as it should.

What is the relationship between IP and ICMP?

ICMP creates and sends messages to the source IP address indicating that a gateway to the internet, such as a router, service or host, cannot be reached for packet delivery. Any IP network device has the capability to send, receive or process ICMP messages.

What is ICMP and how does it work?

ICMP is a network level protocol. ICMP messages communicate information about network connectivity issues back to the source of the compromised transmission. It sends control messages such as destination network unreachable, source route failed, and source quench.

Is ICMP a Layer 3?

Is ICMP a layer 3?

Does ICMP use IP?

ICMP uses the basic support of IP as if it were a higher-level protocol, however, ICMP is actually an integral part of IP. ICMP is a network-layer protocol. There is no TCP or UDP port number associated with ICMP packets as these numbers are associated with the transport layer above.

Is ping good or bad?

Ping is measured in milliseconds (ms), and the closer your ping is to zero, the better. A ping under 20 ms is very good, and just under 100 ms is average. If you experience anything above 150 ms, you will detect delays in your gaming experience, such as lagging or freezing.

What is the normal ping?

Ping amounts of 100 ms and below are average for most broadband connections. In gaming, any amounts below a ping of 20 ms are considered exceptional and “low ping,” amounts between 50 ms and 100 ms range from very good to average, while a ping of 150 ms or more is less desirable and deemed “high ping.”
