The IP address is a 32-bit address used to identify devices on a network, while the MAC address is a 48-bit address assigned to the network interface card of a device.

What calss is the address 10.1.1.2 255.0.0.0
- A
- B
- C
- D
- E
Correct Answer

A. A

Explanation

The given IP address 10.1.1.2 with subnet mask 255.0.0.0 belongs to class A. In classful IP addressing, class A addresses have the first octet in the range of 1-126, and the remaining three octets are used to identify hosts within the network. The subnet mask 255.0.0.0 indicates that the network portion is only the first octet, leaving the remaining three octets for host addressing. Therefore, the given IP address falls within the range of class A addresses.

Correct Answer

A. B

Explanation

The address 172.168.12.0 /16 belongs to Class B. This is because the first octet of the address, 172, falls within the range of 128-191, which is designated for Class B addresses. Class B addresses have a subnet mask of 255.255.0.0 (or /16 in CIDR notation), which means that the first two octets are used to identify the network portion of the address and the last two octets are used to identify the host portion.

A. Host

Explanation

The given IP address 172.168.1.2 with subnet mask 255.255.0.0 represents a host address. The subnet mask 255.255.0.0 indicates that the first two octets (172.168) represent the network address, while the last two octets (1.2) represent the host address within that network. Therefore, the IP address 172.168.1.2 is a host address within the network 172.168.0.0.
