Differences between IPv4 and IPv6

There are various differences between IPv4 and IPv6 protocol including their features, but the crucial one is the number of addresses Address space it generates. IP version 4 IPv4 generates 4. Whereas IP version 6 IPv6 produces 3. First of all, let us understand what is Internet protocol. It is an unreliable and connectionless datagram protocol — a best-effort delivery service.

The internet is an abstraction of physical networks and provides the same functionalities like accepting and delivering packets. It can produce quite a large number of addresses, i. An IPv4 address is a bit binary value, which can be displayed as four decimal digits.

The IPv4 address space offers about 4. Only 3. The other addresses are conserved for specific purposes such as multicasting, private address space, loopback testing, and research. IP version 4 IPv4 uses Broadcasting for transferring packets from one computer to all computers; this probably generates problems sometimes. An IPv4 datagram is a variable-length packet comprised of a header 20 bytes and data up to 65, along with header.

The header contains information essential to routing and delivery. An IPv6 address is a bit binary value, which can be displayed as 32 hexadecimal digits. Colons isolate entries in a sequence of bit Hexadecimal fields. It provides 3. As IPv4 uses two-level address structure where the use of address space is insufficient. That was the reason for proposing the IPv6, to overcome the deficiencies IPv4. The format and the length of the IP addresses were changed along with the packet format and protocols were also modified.

Each packet is consist of a mandatory base header succeeded by the payload. The payload includes two parts namely optional extension headers and data from an upper layer.

The base header consumes 40 bytes, inversely the extension headers and data from the top layer usually hold up to 65, bytes of information. IPv6 retains many of the core concepts from the current protocol, IPv4 but changes most details.

IPv4 was devised as a transport and communications means, but the number of addresses came to exhaustion that was the reason for the development of IPv6.

IPv6 provides scalability, flexibility and seamless possibilities in the field of networking. Your email address will not be published.

IPv4 has bit address length whereas IPv6 has bit address length. IPv4 addresses represent the binary numbers in decimals. On the other hand, IPv6 addresses express binary numbers in hexadecimal.

IPv6 uses end-to-end fragmentation while IPv4 requires an intermediate router to fragment any datagram that is too large. Header length of IPv4 is 20 bytes. In contrast, header length of IPv6 is 40 bytes.

IPv4 uses checksum field in the header format for handling error checking. On the contrary, IPv6 removes the header checksum field. In IPv4, the base header does not contain a field for header length, and bit payload length field replaces it in the IPv6 header.

The option fields in IPv4 are employed as extension headers in IPv6. The header length field which is present in IPv4 is eliminated in IPv6 because the length of the header is fixed in this version.

IPv4 uses broadcasting to transmit the packets to the destination computers while IPv6 uses multicasting and anycasting. Comments Great article. Really Great Information.

Comparison of IPv4 and IPv6

As we know that both IPv4 and IPv6 are the two major internet protocols which are used as the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internet working, and essentially establishes the Internet. So on the basis of functionality and features we can distinguish between both IPv4 and IPv6 protocols.

An Internet Protocol address is also known as IP address. It is a numerical label which assigned to each device connected to a computer network which uses the IP for communication. IP address act as an identifier for a specific machine on a particular network. The IP address is also called IP number and internet address. IP address specifies the technical format of the addressing and packets scheme.

There are various differences between IPv4 and IPv6 protocol including their features, but the crucial one is the number of addresses Address space it generates. IP version 4 IPv4 generates 4. Whereas IP version 6 IPv6 produces 3. First of all, let us understand what is Internet protocol. It is an unreliable and connectionless datagram protocol — a best-effort delivery service. The internet is an abstraction of physical networks and provides the same functionalities like accepting and delivering packets.

IPv4 vs IPv6 — What’s The Difference Between the Two Protocols?

Internet Protocol IP is a set of rules that help with routing packets of data so that the data can move across networks and make it to the right destination. When a computer tries to send information, it gets broken down into smaller chunks, called packets. In order to make sure these packets all make it to the right spot, each packet includes IP information.

Basic Comparison. Basic architecture is 64 bits for the network number and 64 bits for the host number. Often, the host portion of an IPv6 address or part of it will be derived from a MAC address or other interface identifier.

Difference between IPv4 and IPv6

IPv4 provides an addressing capability of approximately 4. It is replacing IPv4 to accommodate the growing number of networks worldwide and help solve the IP address exhaustion problem. IPv4 uses four 1 byte decimal numbers, separated by a dot i.

The basic difference between IPv4 and IPv6 is the standard version of the internet protocol both are supporting. Internet Protocol, also known as IP, is the principal communications protocol that establishes the internet via transference of datagrams across network boundaries. It is operated by two IP addresses, one is the host source and the other is the destination address. Both versions of IP principally perform the same function however, they vary in technique. IPv6 is developed to make for the shortage of IP addresses.


IPv4 & IPv6 are both IP addresses that are binary numbers. IPv4 is 32 bit binary number while IPv6 is bit binary number address. IPv4 address are separated by periods while IPv6 address are separated by colons. Both are used to identify machines connected to a network.
