checksum

The 16bit checksum field is used for error-checking of the header.

differentiated_services

The TOS field is used to carry information to provide quality of service features.

fragment_flag

A three-bit field follows and is used to control or identify fragments.

fragmentation_offset

The fragment offset field specifies the offset of a particular fragment relative to the beginning of the original unfragmented IP datagram.

identification

This field is an identification field and is primarily used for uniquely identifying fragments of an original IP datagram.

The Internet header length field of the packet. Could have None value.

ip_address_destination

An IPv4 address indicating the receiver of the packet.

ip_address_source

An IPv4 address indicating the sender of the packet.

length

Total length of the message.

option

The options of the packet.

protocol_byte

The protocol version byte.

time_to_live
