What Is One Advantage That The Ipv6 Simplified Header Offers Over Ipv4?
The one advantage that the Ipv6 simplified header offers over Ipv4 is that it can provide privacy and authentication features. Today, let us learn the advantages of IPv6 over IPv4. The IPv6 can able to provide four times more billion addresses than the IPv4 routing, this is taken as the biggest benefit of the IPv6 over the IPv4.
We have more number of the address in the IPv6 when we compare it with the IPv4. All the blocks of the IPv4 are get allocated with the addresses of the IPv4. In IPv6, we do not use any address resolution protocol. The privacy and the authentication features are present in the IPv6, which is not existing in IPv4.
The versions of the internet protocol are IPv4 and IPv6. The IP address consists of two parts. They are the network address and the host address. The size of the IPv4 is 32 bits which are separated by periods. The range of the IPv4 is from 0 to 255. The IPv4 consists of four sets which are of eight binary bits. These sets can be called octets.128 64 32 16 8 4 2 1. Each bit on this octet can be 0 or it can be 1. If we place 1 at that octet then we will count that octet, if we place 0, then we do not count that octet.
The IPv6 is of 128 hexadecimal addresses. The hexadecimal is nothing but, it has both the alphabets and the numbers in it. It consists of 8 sets. Each set has 16 bits in it. It is separated by the colons. We consider IPv6 as the next generation of the IPv4.
Each hexadecimal character will represent 4 bits, so we need to convert 4 bits at a time to convert into the hexadecimal character.
The messages in the IPv6 are sent through the IPv6 packets and all the internet control message protocol version messages are sent through the IPv6 packets.
We have two header lengths in the IPv4, which is got eliminated in the IPv6 since in IPv6 we are dealing with the fixed-length header of 40 bits.
The IPv6 has 28 bits for real-time support, whereas IPv4 has only 32 bits in it.
The IPv6 supports fast processing at the routers when we compare it with the IPv4. It can also support real-time applications other than the IPV4. Presently the internet has provided a speed in Gigabits per second, so it is necessary for the new version protocol such as IPV6 to provide the fast processing.
And as the internet has evolved rapidly, there is also a need to see upon in terms of security. Hence, IPv6 also provides some security support. And with the increase in the wireless network, mobility support is also required. The major advantage of IPv6 is that we have backward compatible support from the IPv4. We can send the information to multiple hosts or users at the same time since the ipv6 supports multicast support.
