(B)True. The first address (network address) in a subnet can be obtained by setting the host bits (the rightmost 32-n bits) to 0.
(C) False. Class C addresses (typically in the range 192.0.0.0 to 223.255.255.255) are used for unicast communication, not multicast. Multicast addresses are in the range of 224.0.0.0 to 233.255.255.255.
(D) True. IPv4 addresses are divided into five classes: A, B, C, D (for multicast), and E (reserved for experimental use).
(E) True. Supernetting involves combining multiple smaller networks (subnets) into a larger network by adjusting the subnet mask to cover a larger range of IP addresses.
(B)True. The first address (network address) in a subnet can be obtained by setting the host bits (the rightmost 32-n bits) to 0.
(C) False. Class C addresses (typically in the range 192.0.0.0 to 223.255.255.255) are used for unicast communication, not multicast. Multicast addresses are in the range of 224.0.0.0 to 233.255.255.255.
(D) True. IPv4 addresses are divided into five classes: A, B, C, D (for multicast), and E (reserved for experimental use).
(E) True. Supernetting involves combining multiple smaller networks (subnets) into a larger network by adjusting the subnet mask to cover a larger range of IP addresses.
