How have the IPv4 limitations been solved? (select all that apply) 1 point By creating more IPv4 address By using DNS By implementing the IPv6 protocol By using Network Address Translation
The Correct Answer and Explanation is:
The limitations of IPv4 have been addressed in the following ways:
- By implementing the IPv6 protocol: IPv6 was introduced as the successor to IPv4 to address the shortage of IP addresses. IPv4 has a limit of about 4.3 billion unique addresses, which is insufficient given the rapid expansion of internet-connected devices. IPv6, on the other hand, uses 128-bit addresses, providing a virtually unlimited number of IP addresses (approximately 340 undecillion addresses). This vast expansion of address space ensures that every device can have a unique address, solving the problem of IPv4 address exhaustion.
- By using Network Address Translation (NAT): NAT is a technique used to mitigate the shortage of IPv4 addresses. It allows multiple devices on a local network to share a single public IP address. With NAT, devices within a private network (like in a home or office) can communicate with the internet using one public address. This reduces the number of public IP addresses needed and effectively extends the lifespan of IPv4.
Incorrect options:
- By creating more IPv4 addresses: This is not a solution to the limitations of IPv4. The number of available IPv4 addresses is fixed at approximately 4.3 billion, and there’s no way to increase this number. The problem lies in the lack of available addresses, not in the creation of more.
- By using DNS: DNS (Domain Name System) is used for translating human-readable domain names (like google.com) into IP addresses. While DNS helps manage network resources more efficiently, it does not solve the IPv4 address limitation. DNS is about naming, while IPv4 address exhaustion is about the availability of address space.
In conclusion, the implementation of IPv6 and the use of NAT have been key solutions to overcome the limitations posed by IPv4 address exhaustion
