What is IPV4 and IPV6 ? can anyone tell the difference between these two?

Question

Hi All,

I want to know, various types of Attach Request for Phone and Wifi devices and what will be the respective attach Accept response from the network in successful Case. I am looking for Network response both in case if network supports VoLTE (Like RJIO)and if network doesnot supports volte (Airtel)....

Answer 1

We are still on IPv4 mostly but that gives you maximal number of combinations of 32 bits or 4 Byte.
In Shortly there will be no more enough numbers(addresses) with 4 Byte so they created IPv6
with total number of combinations of 50bits or 6 Byte.

Answer 2

An IP address is binary numbers but can be stored as text for human readers. For example, a 32-bit numeric address (IPv4) is written in decimal as four numbers separated by periods. Each number can be zero to 255. For example, 1.160.10.240 could be an IP address.

IPv6 addresses are 128-bit IP address written in hexadecimal and separated by colons. An example IPv6 address could be written like this: 3ffe:1900:4545:3:200:f8ff:fe21:67cf (see "What does an IPv6 address look like?")

The Benefits of IPv6 over IPv4
While increasing the pool of addresses is one of the most often-talked about benefit of IPv6, there are other important technological changes in IPv6 that will improve the IP protocol:
- No more NAT (Network Address Translation)
- Auto-configuration
- No more private address collisions
- Better multicast routing
- Simpler header format
- Simplified, more efficient routing
- True quality of service (QoS), also called "flow labeling"
- Built-in authentication and privacy support
- Flexible options and extensions
- Easier administration (say good-bye to DHCP)
