Question

2. What is the difference between size of IPv4 and IPv6 addresses? (15 pts.) 3. Determine the prefix, the subnet mask, and the range of addresses for an address space represented by 123.87.252.0/22. (20 pts.)

Answer 1

Answer 2:

• First, the "v" in IPv4 and IPv6 represents the version of IP using. So let we start the difference from v only. IPv4 uses version 4 of IP while IPv6 uses version 6.
• Now, If we talk about the lengths then IPv6 is way larger than the IPv4. IPv4 has a 32-bit length of address while IPv6 has 128 bit.
• Address generation space: IPv4 generates 4.29 x 109 while as IPv6 generates 3.4 x 1038
• Representation of IP address in IPv4 is in decimal while as it is in hexadecimal in case of IPV6.
• If we talk about the security then IPV6 is more secure than IPv4 because there is no facility like encryption and authentication in IPV4 but in IPv6, there is.

During the beginning period of the Internet, IPv4 is generally utilized wherever yet because of the everyday increment in the utilization of the Internet for a few purposes separated from associations to a home system and cell phones, the address space is depleted.

In this way, IPv6 innovation which has an interminable addressability with cutting edge highlights like auto-setup and versatility and so forth was presented.
