Question

Using the following information (Machine’s IP=33.32.31.30, Machine’s Netmask=/29, Parent’s Netmask=255.255.240.0 ), determine

a. how many bits are used for host number on the child network (subnet)

b. how many usable addresses can exist on this child network (subnet)

c. what the first usable address is on this child network (subnet)

d. what the last usable address is on this child network (subnet)

e. what the child network’s (subnet's) broadcast address is

f. what the child network's (subnet's) network number is

(Be sure not to include any spaces in your answers. When giving addresses, do not include netmasks with them.)

Answer 1

IP Address = 33.32.31.30
Machine netmask = /29
Machine network Address = 33.32.31.00011000 = 33.32.31.24
(a)Bits are used for host number on the child network = 32 - 29 = 3
(b)Usable addresses can exist on this child network = 2³ - 2 = 6
(c)First usable address is on this child network = 33.32.31.00011001 = 33.32.31.25
(d)Last usable address is on this child network = 33.32.31.00011110 = 33.32.31.30
(e)BroadCast Address = 33.32.31.00011111 = 33.32.31.31
(f)Network Address = 33.32.31.00011000 = 33.32.31.24
