1.2 A firm is assigned the network part 128.171. It selects a 10-bit subnet part.
a) Draw the bits for the four octets of the IP address of the first host on the first subnet. (Hint: as we donât use all 1 or all 0, the 1st subnet/host is 00â¦01, while the last subnet/host is 11â¦10. The number of 1&0 in the expression depends on the length of subnet/host part)
b) Convert this answer into dotted decimal notation.
c) Draw the bits for the second host on the third subnet. (In binary, 2 is 10, while 3 is 11.)
d) Convert this into dotted decimal notation.
e) Draw the bits for the last host on the third subnet.
f) Convert this answer into dotted decimal notation.
