Write the given subnet mask in binary.
Write the IPv4 host address in binary.
Knowing the class of the host address, the subnet bits of the mask should be apparent. Using the mask bits as a guide, draw a line between the last network bit and the first subnet bit of the address. Draw another line between the last subnet bit and the first host bit.
Write the network and subnet bits of the address, setting all host bits to zero. The result is the address of the subnet to which the host address belongs.
Again write the network and subnet bits of the address, this time setting all host bits to one. The resul...
