What is the difference between IPv4 and IPv6?

Q.  What is the difference between IPv4 and IPv6?
- Published on 23 Sep 15

a. The IPv4 address is written in hexadecimal value while the IPv6 address is written by dotted-decimal notation.
b. In IPV4 source and destination address is 128 bits while in IPv6 it is 32 bits.
c. The IPv4 node has only stateful auto-configuration while the IPv6 node has both a stateful and a stateless address auto-configuration.
d. In IPv4 the IPsec support is required while in IPv6 it is optional.

ANSWER: The IPv4 node has only stateful auto-configuration while the IPv6 node has both a stateful and a stateless address auto-configuration.

    - IPv4 :

        - IPv4 (Internet Protocol version 4) is a protocol for use on packet-switched Link Layer networks (eg. Ethernet)

        - Security is limited in IPv4 between two networks.

        - IPv4 header has a checksum, which must be computed by each router.

        - The IPv4 address is written by dotted decimal notation, eg. 131.4.8.21

        - It provides an addressing capability of approximately 4.3 billion address.

    - IPv6 :

        - IPv6 (Internet Protocol version 6) is more advanced and has better features compared to IPv4.

        - It has the capability to provide an infinite number of addresses.

        - IPv6 address is written in hexadecimal and consists of 8 groups, eg. FABC:AC77:7834:2222

        - IPv6 is designed to satisfy the growing and expanded need for network security.
