Which of the following statements is true?(i) An address with all bits...
Statement (i): An address with all bits 1 is interpreted as all networks or all hosts.
- This statement is true.
- An address with all bits 1 is known as the broadcast address.
- When this address is used, it is interpreted as a request to send data to all networks or all hosts within a network.
- For example, in a network with an IP address of 192.168.1.0 and a subnet mask of 255.255.255.0, the broadcast address would be 192.168.1.255.
Statement (ii): The class A network 128.0.0.0 is defined as the loopback network.
- This statement is false.
- The loopback network is defined as 127.0.0.0/8, not 128.0.0.0.
- The loopback address 127.0.0.1 is used to test network connectivity on a local machine.
- It is commonly used for troubleshooting and is not assigned to any physical network interface.
Therefore, the correct answer is (i) only.
Which of the following statements is true?(i) An address with all bits...
Explanation:
Address with all bits 1:
- An address with all bits 1 is interpreted as all networks or all hosts.
- When all bits in an IP address are set to 1, it represents a broadcast address.
- In IPv4, a broadcast address is used to send data to all possible destinations within a network.
- Therefore, an address with all bits 1 does not represent a specific network or host, but rather a broadcast address.
Class A network 128.0.0.0:
- The Class A network range is from 0.0.0.0 to 127.255.255.255.
- The address 128.0.0.0 falls outside the range of Class A networks.
- The loopback network is defined by the address range 127.0.0.0 to 127.255.255.255.
- Therefore, the statement that the Class A network 128.0.0.0 is defined as the loopback network is incorrect.
Therefore, the correct statement is that an address with all bits 1 is interpreted as all networks or all hosts.
