Answer #1

IP stands for Internet Protocol and are set of internationally agreed rules to transmit datagrams through the internet. IPv4 is the fourth version of the internet protocol and was first used in the original ARPANET in 1983. It is the most popular method to route internet traffic even today. IPv4 has been surpassed by IPv6 but not in usage yet.

One of the main differences between the protocols are that IPv4 uses 32-bit format addresses while IPv6 uses 128 bit addresses. This is done so because IPv6 was designed to tackle the huge growth in Internet users. IPv4 can support up to around 4 billion devices (2^32 unique addresses). So a 128-bit IPv6 address format can cover most of the Earth’s population.

IPv4 is written in decimal (base 10) number system as four numbers separated by periods. Each number can be a number from 0 to 255. e.g. 192.168.230.1 is a valid IPv4 address.

IPv6 is written in hexadecimal (base 16) number system and they are separated by colons. e.g. 3ffe:1900:4545:3:200:f8ff:fe21:67cf is a valid IPv6 adress.

Companies that are deploying IPv6:

NTT

Verizon Wireless

AT&T

T Mobile

Sprint

Reliance Jio    

Advantages of IPv6 over IPv4:

IPv6 Addresses can be processed faster

IPv6 supports more addresses

IPv6 has built in security features (Security features were later added in IPv4 as an option)

DHCP is no longer required

True Quality of Service

Auto Configuration

Advantages of IPv4 over IPv6:

There are not many advantages of using IPv4.

It is easy to remember

Requires less memory space

Existing infrastructure supports IPv4 mostly

Legacy Support
