Question
The IP address 10.1.1.1 belongs to which class of IP address space?
Answers
Explanations
A
The IP address 10.1.1.1 belongs to the Class A range of IP address space.
IP addresses are used to identify devices on a network. They are divided into five classes based on the range of the first octet (the first 8 bits) of the IP address. The five classes are Class A, B, C, D, and E. Each class has a different range of IP addresses that it can use.
Class A IP addresses use the first octet to identify the network, and the remaining three octets to identify hosts on that network. The range of Class A IP addresses is from 1.0.0.0 to 126.0.0.0. The IP address 10.1.1.1 falls within this range, so it belongs to Class A.
Class B IP addresses use the first two octets to identify the network, and the remaining two octets to identify hosts on that network. The range of Class B IP addresses is from 128.0.0.0 to 191.255.0.0.
Class C IP addresses use the first three octets to identify the network, and the remaining octet to identify hosts on that network. The range of Class C IP addresses is from 192.0.0.0 to 223.255.255.0.
Class D IP addresses are used for multicast traffic, and Class E IP addresses are reserved for future use.
In summary, the IP address 10.1.1.1 belongs to the Class A range of IP address space, which uses the first octet to identify the network and the remaining three octets to identify hosts on that network.
