Icmp Packet Size The minimum size of any ICMP packet or message is much lower than the minimum Ethernet frame size on an Ethernet network which is 64 bytes Because of this
I sniffed ping packet frame size says 74 bytes which would be 20 bytes of IP header 8 bytes of ICMP header 32 data 18 bytes of min ethernet frame In my case i did All ICMP packets have an 8 byte header and variable sized data section The first 4 bytes of the header have a fixed format while the last 4 bytes depend on the type code of that ICMP packet 1 for IPv4 and 3 for IPv6

Maximum Transmission Unit MTU Check Using Ping Packet

In order to calculate an ICMP packet in a router using wireshark ICMP packet 8 Bytes total length IP packets 20 Bytes Frame 14 Bytes so If you are initiate a ping then total of 1500 20 8 1472 Bytes Payload The max size is 65507 65535 max ip length 20 ip hdr 8 icmp ping hdr 65507 Windows OS blocks max size at 65500 but in Linux you can ping up to the real limit
It is layer 3 i e network layer protocol used by the ping command for sending a message through ICMP payload which is encapsulated with IP Header Packet According to MTU the size of the ICMP packet cannot be 65535 bytes is the maximum allowed size of a IPv4 network packet while 20 and 8 are the sizes of the IP and ICMP headers which leaves up to 65507 bytes for the ICMP data

When you specify a packet size for a ping command that value represents the size of the payload that will be used by the ICMP packet The ICMP header itself is 8 bytes The IP header is 20 When the size of the ICMP packet is set to 1500 bytes that is not taking into account the overhead of the IP header For the command to succeed the payload of the ICMP packet
Change Ping Packet Size in Ping Command In some scenarios we may want to use s to increase the packet size from the default value of 64 bytes For example to increase the I would think is the same size As it the receiver would only reply your packet so it would only change icmp type and source destination IP check the reply C Documents and
