The following is the old page content

The basic network transmission protocol of the Internet and every network based on [TCP/IP].

This is the [C] structure that represents an [IP] header (version 4):

struct iphdr {
 #if defined(__LITTLE_ENDIAN_BITFIELD)
         __u8    ihl:4,
                 version:4;
 #elif defined (__BIG_ENDIAN_BITFIELD)
         __u8    version:4,
                 ihl:4;
 #else
 #error  "Please fix <asm/byteorder.h>"
 #endif
         __u8    tos;
         __u16   tot_len;
         __u16   id;
         __u16   frag_off;
         __u8    ttl;
         __u8    protocol;
         __u16   check;
         __u32   saddr;
         __u32   daddr;
         /*The options start here. */
 };

The [IP] protocol is the part of [TCP/IP] that allows packets of data to pass from one host to another.
It's possible to think at an IP packet as a piece of data with a source and destination address attached,
at every point of it's trip the destination address is used to select the right way in order to
reache the destination host.

In a [TCP/IP] network, hosts are identified by IP addresses. An [IP address] in the IPv4 protocol is a 4 byte number,
usually represented as a four 8-bit quantity separated by a point (example: 192.168.1.6).

The [IP] protocol works in a *best effort* fashion. This means that there is no guarantee that packets will eventually
reach the destionation. They may be lost, duplicated, out of sequence. Higher level protocols like [TCP] add the reliability
abstraction using the [IP] protocol as a base.

A protocol strictly related to the [IP] protocol is the [ICMP].
