Question

The world is currently in a transition to using IPv6, a newer version of the IP protocol that uses 128-bit addresses instead of 32-bit addresses used by IPv4. What is the main problem that IPv6 was created to solve?

Answer 1

Answer:

IPv4 could not assign every device unique IP address.

Explanation:

IPv4 (Internet Protocol Version 4) uses 32-bit addresses which allows $2^{32}$ addresses in total.

An example of IPv4 address is 192.168.0.11

IPv6 (Internet Protocol Version 6) uses 128-bit addresses and solves the shortage of unique IPv4 addresses problem.

An example of IPv6 address is fe80::90ce:e962:35dd:cfa5

IPv6 has also some other advantages like

• no need for network address translation

• simple routing

• administration is easier

• configured automatically
