What is IP header and TCP header?

The IP packet contains header and data sections. The IP data section is the TCP segment, which itself contains header and data sections. Each TCP segment contains a header and data.

How long is TCP header?

20 bytes
TCP wraps each data packet with a header containing 10 mandatory fields totaling 20 bytes (or octets). Each header holds information about the connection and the current data being sent.

Is TCP header size fixed?

Since each of the header’s mandatory fields are fixed in size, the smallest this value can be is 5. Thus, a TCP header can be no larger than 60 bytes (15 × 32 bits = 480 bits = 60 bytes).

How many bytes are in a TCP header?

Specifies the size of the TCP header in 32-bit words. The minimum size header is 5 words and the maximum is 15 words thus giving the minimum size of 20 bytes and maximum of 60 bytes, allowing for up to 40 bytes of options in the header.

What is an IPv4 packet header?

Internet Protocol Version 4- IPv4 short for Internet Protocol Version 4 is the fourth version of the Internet Protocol (IP). IP is responsible to deliver data packets from the source host to the destination host. This delivery is solely based on the IP Addresses in the packet headers. IPv4 is the first major version of IP.

What is the size of a packet header?

An Internet Protocol version 4 packet header (IPv4 packet header) contains application information, including usage and source/destination addresses. IPv4 packet headers contain 20 bytes of data and are normally 32 bits long.

What is an example of an IP packet?

IP Packet. You can say, that somehow everything you do on the Internet is a matter of packets, and to be more precise, of IP packets. For example, all the Web pages that you receive on your computer, come in a variety of packages, and all the emails you send are also transmitted in packets.
