you need to reallocate 4 bits to creat 16 subnets. how do I get that? easy! 2 to the power of 4 gives us 16 subnets.

How to use 172.16.0.0 to create 32 subnets?
172.16.0.0 is really a B Class address with 16 network bits and 16 host bits, i.e. Network Address 172.16.0.0 has 255.5255.0.0 as Subnet mask in Classful Addressing. To create 32 (25) subnets we will use first five bits for Network part and will leave 3 bits as Host bits in third octet. Now Addressing will be:Network Address: 172.16.0.0\21 or 172.16.0.0 Subnet Mask: 255.255.248.0First two networks will be : (1) 172.16.0.0-172.16.7.255\21, (2) 172.16.8.0-172.16.15.255\21 and last two networks will be (1) 172.16.240.0-172.16.247.255\21, (2) 172.16.248.0-172.16.255.255\21.(Note to use Zero subnet - remember to use IP SUBNET ZERO command.)
What are the steps in subnetting?
A service provider has given you the Class C network range 209.50.1.0. Your company must break the network into 20 separate subnets. Step 1) Determine the number of subnets and convert to binary - In this example, the binary representation of 20 = 00010100. Step 2) Reserve required bits in subnet mask and find incremental value - The binary value of 20 subnets tells us that we need at least 5 network bits to satisfy this requirement (since you cannot get the number 20 with any less than 5 bits -- 10100) - Our original subnet mask is 255.255.255.0 (Class C subnet) - The full binary representation of the subnet mask is as follows: 255.255.255.0 = 11111111.11111111.11111111.00000000 - We must "convert" 5 of the client bits (0) to network bits (1) in order to satisfy the requirements: New Mask = 11111111.11111111.11111111.11111000 - If we convert the mask back to decimal, we now have the subnet mask that will be used on all the new networks -- 255.255.255.248 - Our increment bit is the last possible network bit, converted back to a binary number: New Mask = 11111111.11111111.11111111.1111(1)000 -- bit with the parenthesis is your increment bit. If you convert this bit to a decimal number, it becomes the number "8‟ Step 3) Use increment to find network ranges - Start with your given network address and add your increment to the subnetted octet: 209.50.1.0 209.50.1.8 209.50.1.16 ...etc - You can now fill in your end ranges, which is the last possible IP address before you start the next range 209.50.1.0 -- 209.50.1.7 209.50.1.8 -- 209.50.1.15 209.50.1.16 -- 209.50.1.23 ...etc - You can then assign these ranges to your networks! Remember the first and last address from each range (network / broadcast IP) are unusable
The two parts of MAC addresses?
Yes - the first bits specify the network, the remaining bits, a host within a network. There is no fixed number of bits for the network; this may vary.Yes - the first bits specify the network, the remaining bits, a host within a network.

How many bits comprise the network portion of a class c address?
Thirty bits make up the network portion of a class C address. Three bits are borrowed for the subnet mask. There is also a class A and a class B that are comprised of bits.
How many hosts can each class b network have?
16 384 networks are available in Class B network.
What does it mean to borrow 4 bits for subnets?
When you borrow bits for a subnet you are intruding into the client portion of an IP address. As a result, you will lose clients in your network because the "borrowed" portion becomes the extended network prefix. This allows you to separate your bigger network into smaller, logical networks (subnets). The number of bits borrowed will indicate the total number of smaller subnets that you can support in your network. In each case, regardless of class of address, borrowing 4 bits gives a total of 14 subnets (in the classical sense) and 16 subnets (in Cisco).
How many subnets are provided in a network with 7 bits of subnetting?

How many subnets and hosts per subnet can you get from the network 172.16.0.0?
There are 16 bits available; it is up to you how many of those bits you reserve for the subnet, and how many for the individual hosts within each subnet.
How many subnets are available in prefix?
It depends on how many bits you are using for the network prefix. The formula is 2n - 2 for the number of subnets available in a prefix, or 2n if you allow the use of the 0th subnet.
How many subnets can you have in a class C network with a 26 bit mask?
A Class C IP address has 24 bits for network and 8 bits for host. So to have a subnet mask of 26 bits, you will need to use 2 bits from host part.Number of subnets is given by the formula : 2^(no. of bits used from host part).Hence number of subnets in this case would be = 2^2 = 4.For e.g. if the class C IP address is 200.168.210.0the 4 subnet addresses would be :11001000.10101000.11010010.00000000 = 200.168.210.011001000.10101000.11010010.01000000 = 200.168.210.6411001000.10101000.11010010.10000000 = 200.168.210.12811001000.10101000.11010010.11000000 = 200.168.210.192Note: The digits in bold are the mask bits.
How do you divide class B network into eight subnets?
From the 16 bits reserved for the host, you "lend" 3 bits for the subnet. That gives you the possibility of dividing into eight subnets. The remaining 13 bits indicate the host in each subnet. - To see the complete steps in more detail, do some Internet searching on subnetting.
How Given a Class C network 200.1.1.0 We want 5 subnets each with 30 hosts on it. How many bits to borrow How many bits to leave What is the subnet mask ( in dot notation and in CIDR notation)?
Given a Class C network: 200.1.1.0 We want 5 subnets, each with 30 hosts on it. How many bits to borrow ? How many bits to leave? What is the subnet mask? ( in dot notation and in CIDR notation)
How many bits are borrowed from a class B host address to create 30 new subnets?
5 bits are necessary to create up to 30 subnets.
How many Subnets can you create on a Class C address with the subnet mask being 255.255.255.192 the answer i got was wrong and I don't understand where I went wrong please help. Thank you?
192 is equal to 2 bits borrowed 2^2 = 4 the number of subnets and host are 64 because 2 bits borrowed from the 8 bits of a class C network is 6, therfore 2^6 = 64.
How many host bits are borrowed if four subnets are created?

If you have been assigned network ID 172.16.50 with a subnet mask of 255.255.255.0 What is the maximum number of workstations you can have on the subnet?
Since this is a class B network you have borrowed 8 bits for subnets. This leaves 8 bits left (1 octet) for clients/workstations. That gives you a maximum of 254 clients per subnet.
