Header Checksum (16 bits): Helps detect corrupted packets.Protocol (8 bits): This field specifies the next encapsulated protocol.Time to Live (TTL – 8 bits): Identifies the life of the datagram.Fragment Offset (13 bits): To assemble fragments.Flags (3 bits): Fragment, No fragment, or more fragment.Identification (16 bits): Identifies fragments of other datagrams.Total Length (16 bits): Length of the datagram.Type of Service (TOS – 8 bits): Specifies how the datagram is handled.IHL (bits 4): Internet Header Length (IHL) specifies the header’s length.Version (bits 4): Specifies the version of the packet.So let’s define what these packet fields are: Knowing what an IPv4 carries in its control header will help you understand the crucial differences between IPv4 vs. The arrow indicates the first bits in the packet header where the protocol’s version is displayed. The first four bits of a packet header (Version) indicate the IP version. The minimum size of an IPv4 packet can be from 20 bytes (which is the control or header) to a maximum of 60 bytes. The size of an IPv4 packet may vary in bits due to the Options and Data fields. The control plane is also known as the header, while the data plane contains the payload. The IP packets consist of control and data planes. IPv4 gives a unique identifier to each device connected to a network (including the Internet). Version number 4 of IP is described in RFC 791 from 1981. The IPv4 (Internet Protocol version 4) is the dominant internetworking protocol that makes the entire Internet work. IPv4 broadcasts, while IPv6 multicasts and anycasts.In IPv4, IPSec must be implemented, while in IPv6, it is built-in.IPv6 uses leaner headers (control bits).Different local address assignments (DHCP vs.IPv6’s Global unique addresses are different from IPv4’s public addresses.Address types and scopes are different.IPv6 uses shortening techniques IPv4 doesn’t.IPv4 and IPv6 have different address notations.IPv6 provides a mind-blowing number of address combinations.Then we’ll describe their 11 key differences. In this post, we’ll go through both IP protocols- a profound technical explanation of both protocols. IPv6 was designed with one purpose in mind- to replace IPv4. IPv6 is newer, more daunting, and more sophisticated. Although IPv4 is still what holds the Internet together, IPv6 is slowly gaining interest. IPv4 is the most common and widely used Internet Protocol version for now. IPv6? What are their differences, their pros, and their cons?
