Previous Year Question (PYQs)



Consider the following two statements with respect to IPv4 in computer networking:

$P$: The loopback IP address is a member of the class B network.

$Q$: The loopback IP address is used to send a packet from the host to itself.

What can you say about the statements $P$ and $Q$?






Solution

Loopback addresses belong to the $127.0.0.0/8$ range.

This range belongs to class A, not class B.

So, statement $P$ is false.

Loopback address is used by a host to send packets to itself for testing and internal communication.

So, statement $Q$ is true.
