C is the "BEST" answer (the most traditional). However any of the class A 127 address would work. Try 127.0.0.1 and then 127.0.0.255 (both valid 127 addresses) and compare the PING output. Interesting.

127.0.0.0 should be loop back IP Address.

Can we use 127.0.0.0?

Smriti said:   6 years ago
Explain it clearly please.

Aarav said:   6 years ago
Option C suits correct. As the question asked for host ping.

C is the answer.

Loop back address is 127. So that 127.0.0.0 is network Id and 127.0.0.255 is broadcast id. We can check through first valid ip (ie) 127.0.0.1.
