Answer:
CIDR is based on a variable-length subnet masking technique, which allows a new method of representation for IP addresses. Routing prefix is written with a suffix number of bits of the name, such as 123.0.0.0/8, as the CIDR network has the smallest possible amount of hosts.
Explanation:
CIDR ( Class Inter-Domain Routing ) It is a method that is allocating IP addresses and routing the IP. CIDR is introduced in 1933 and replace the architecture of network design on the internet. CIDR slows down the growth of the routing across the web and helps to slow the IP addresses such as IPv4 addresses.
CIDR consists of two groups of bits in the address. In the new age, the network prefix identifies the whole network. This is used as the basis of routing between IP networks and allocation policies.
IPv4 in-network prefix is 8-bit groups.
A typical IPv4 address is 192.168.0.5 the lowest value is 0, and the highest value is 255
In the given choices, 123.0.0.0 / 8 of the possible smallest number of hosts.
