|SUBNETTING IPv4 CLASS "B" ADDRESS|
(hint:2^n-2 subnets for n bits taken from host addresses; 2^m -2 hosts for m available bits -(m+n) = total number of bits not part of network address)
1) You are at a large company and decided to implement a private address space for your internal network. You decide to use the class B address (172.17.0.0/16) - this means your network address is 172.17.0.0. The number of bits in the subnet mask is 16 and your default subnet mask is 255.255.0.0
a) How many hosts are on this network?
b) why would you not want this many hosts on your network?
c) you decide to have 50 networks. How many bits do you need to take from the host part of the address to create 50 networks?
d) What is the new Subnet mask?
e) How many usable hosts are on each subnet?
f) List the first three usable subnets
g) List the last three usable subnets.
h) List the first three usable host addresses in the third subnet.
i) List the broadcast address in the third subnet.
IPv4 CLASS "C" ADDRESS
2) Assume that your company has purchased the 18.104.22.168 class C network block. This is a range of public addresses which you will assign to the internet accessible devices such as your NATs and routers
a) you decide to have 14 hosts on each subnet - how many bits will you need
b) this leaves ___________binary digits are left for the subnet address.
c) This will give you ___________ subnets.
d) Specify the subnet mask in a dotted decimal notation.
e) Specify the subnets in dotted Decimal notation and in binary format for the last octet.
f) List the range of usable host addresses on the second subnet
g) what is the broadcast address for the second subnet.
