Note: According to Chegg guidelines, only the first 4 sub parts have been answered. Please post rest of the questions in separate post.
IP address refers to Internet Protocol and it is a unique number corresponding to each information technology device like printer, modem. This unique number, IP address allows the devices to communicate with each other on a network.
1)
The difference between an IP address and a Mac address is as follows:

2)
The requirements of IPv6 protocol are as follows:

  • The IPv6 addresses are more secured and provide end-to-end encryption of data. It reduces the chances of man-in-the-middle attack.
  • Since, the number of users of internet are increasing day by day so, IPv6 is more scalable as compared to IPv4 in supporting the large number of IP addresses.
  • The IPv6 enables more users/devices to connect to each other such that their addresses are unique and the traditional firewall issues are not faced by the users.

2.1)
The size of IPv4 address is 32 bits which is equivalent to 4 bytes.
The size of IPv6 address is 128 bits which is equivalent to 16 bytes.

3)
The difference between IPv4 and IPv6 addresses are as follows:

4)
The different problems associated with IPv4 protocol is that it occupies 32 bit which is not enough for allocation of address, therefore the address space gets exhausted.
The above problem associated with IPv4 protocol is solved using IPv6 protocol
IPv6 protocol provides more address space of 128 bits which is much more than the address space of IPv4 protocol. Moreover, IPv6 is more secured and encrypted.
