Which address is reserved as the IPv4 loopback used to test the local TCP/IP stack?
a.192.168.0.1
b.10.0.0.1
c.127.0.0.1
d.255.255.255.255
Explicación
127.0.0.1 is the loopback address that lets a host test its own TCP/IP stack without touching the physical network. The entire 127.0.0.0/8 block is reserved for loopback. Pinging it confirms the local protocol stack is functioning.
