Which of the following IP addresses are valid Class B host addresses if a default Class B mask is in use?
Which of the following IP addresses are valid Class B host addresses if a default Class B mask is
in use? (Choose two.)
Class A gets roughly half of the IPv4 address space, with all DDN numbers that begin with 1–126.
Class B gets one-fourth of the address space, with all DDN numbers that begin with 128–191.
Class C gets one-eighth of the address space, with all numbers that begin with 192–223.
Class D defines multicast addresses, used to send one packet to multiple hosts, with numbers that begin with 224–239.
Class E defines experimental addresses, with numbers that begin with 240–255.
0 and 127 are reserved
1 and 128 (class A bounds)
128 and 192 (class B bounds)
0 and 127 are reserved
