If you have class B network and want to divide it into subnets, each with 126 hosts, which subnet mask must you use? How many networks will be available? Write down the four addresses (broadcast and network number) for network starting at 131.204.18? Subnet mask is 255.255.255.128 or FFFFFF80 or /25 (all equivalent). There will be 512 networks available. Networks: 131.204.18.0, 131.204.18.128 Broadcast: 131.204.18.127, 131.204.18.255 10. Assume you have 300 hosts and wish to have no more than 50 hosts per subnet. Determine size of address block must you request from ISP? How many class C equal addresses would you require? How many subnets would you have left over from allocation?
