What is the size of the largest possible IP packet?
This 16-bit field defines the entire packet size in bytes, including header and data. The minimum size is 20 bytes (header without data) and the maximum is 65,535 bytes.
How do I know my IP packet size?
The IP header has a ‘Total Length’ field that gives you the length of the entire IP packet in bytes. If you subtract the number of 32-bit words that make up the header (given by the Header Length field in the IP header) you will know the size of the TCP packet.
How do I find my max MTU size?
Add 28 to that number (IP/ICMP headers) to get the optimal MTU setting. For example, if the largest packet size from ping tests is 1462, add 28 to 1462 to get a total of 1490 which is the optimal MTU setting.

How many bytes is an IP packet?
Each IP packet contains both a header (20 or 24 bytes long) and data (variable length). The header includes the IP addresses of the source and destination, plus other fields that help to route the packet.
How many bytes are in the IP header how many bytes are in the payload of the IP datagram?
According to the figure 1, the header length is 20 bytes and the total length is 56 bytes. Therefore, the payload of the IP datagram should be 36 bytes (56 bytes – 20 bytes). 4. Has this IP datagram been fragmented?
How do you ping 1500 bytes?
ping –l > –f > For standard MTU of 1500 bytes, the maximum data size is 1472 bytes (MTU minus 20 bytes IP header and 8 bytes for the ICMP header).
What is the maximum header size of an IP packet in bytes?
The maximum length of an IP header is 24 bytes, or six 32-bit increments. Therefore, the header length field should contain either 5 or 6.
Why is the size of the IP header limited to 60 bytes?
The IHL field can hold values from 0 (Binary 0000) to 15 (Binary 1111). So the longest Internet Header (IP header) size can be 15*32 Bits = 480 Bits = 60 Bytes. This is why the header has a maximum size of 60 Bytes.
What size in bytes were the largest IP packets sent ie at what size did the ICMP echo requests fragment?)?

| IP header | ICMP header | ICMP payload size |
|---|---|---|
| 20 bytes | 8 bytes | 1472 bytes (maximum) |
