What protocol is used by ping?
ICMP
ICMP is probably most well known as the message protocol used for the ping command. A ping command sends an ICMP echo request to the target host.
What is the identifier in ICMP?
The identifier and sequence number may be used by the echo sender to aid in matching the replies with the echo requests. For example, the identifier might be used like a port in TCP or UDP to identify a session, and the sequence number might be incremented on each echo request sent.
What ICMP identifier does Windows ping use?

How do I trace ping packets?
Ping & traceroute tests
- Open the command window by clicking START, then RUN.
- Type PING in the command dialogue window.
- Hit the space bar once.
- Type the IP or website address that you want to ping.
- Hit “Enter” or return on your keyboard.
- You can now move to the next step to perform a TRACERT test (see below)
What is the difference between ICMP and ping?
ICMP is a protocol for sending various messages to report network conditions—it is not ping. The echo request is one of many messages. Ping can be filtered out, but the majority of ICMP message types are required for proper operation of IP, TCP and other protocols.
What is ICMP Traceroute?
A traceroute works by sending Internet Control Message Protocol (ICMP) packets, and every router involved in transferring the data gets these packets. The ICMP packets provide information about whether the routers used in the transmission are able to effectively transfer the data.
What is difference between ping and ICMP?
Internet Control Message Protocol (ICMP) is one of the protocols of the TCP/IP suite. The ICMP echo request and the ICMP echo reply messages are commonly known as ping messages. The ping command sends an ICMP echo request to a device on the network, and the device immediately responds with an ICMP echo reply.
Which port is used by ICMP ping?
ICMP doesn’t use port numbers, so there is no port for ping. Some people may use the phrase “ping a port” informally meaning to open a TCP connection to that port and see if a response is received, but practically speaking, there is no ping port.
How does the Ping protocol identify a port?
The “Ping” protocol is actually using ICMP packets (echo, echo reply etc) to identify if a remote host is “alive” (i.e connected to the network and replying to the ICMP packets). The ping protocol does not send TCP packets to the remote host to identify open ports.
What does Ping mean in the ICMP protocol?
The Ping utility uses the echo request, and echo reply messages within the Internet Control Message Protocol (ICMP), an integral part of any IP network. When a ping command is issued, an echo request packet is sent to the address specified.
What is Ping and what does it mean?
Ping. Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It is available for virtually all operating systems that have networking capability, including most embedded network administration software. Ping measures the round-trip time for messages sent from
How is the ping command used to troubleshoot accessibility?
The Ping Command. The ping command is a very common method for troubleshooting the accessibility of devices. It uses a series of Internet Control Message Protocol (ICMP) Echo messages to determine: Whether a remote host is active or inactive. The round-trip delay in communicating with the host.
