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.
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).
Is it possible to create 9 subnets of equal size or do you have to create a different number of subnets?
Depending on class of network you are planning to use. For class C you can create much more then that (and for the most case for others too).
If you have decided to create 254 subnets on your class b network?
255.255.0.0
How many bits are borrowed from a Class C host address to create 6 new sub-nets?
20
Which class of network license allows the borrowing of 15 bit to create subnets?
- is A
Is 11.255.255.255 a class A broadcast?
Yes - this is a broadcast address for all subnets in the 11.0.0.0 network.
What information is required prior to dividing a netowrk into subnets?
network class network address number of subnets required number of host per subnet
If you have decided to create 254 subnets on your class B network what subnet mask will you use to accomplish this?
255.255.255.0
What is the maximum number of hosts bits that can be borrowed for sub-netting from a Class B address?
14
Assuming no subnetting what are valid Class B host addresses?
A classful class B network has a network range of 128 - 191. For host addresses, anything that is legal for an IP address in the last 2 octets would be a valid host address for a class B with no subnets.
Given class C address with a default subnet mask How many possible subnets and usable hosts if 4 bits were borrowed?
that gives you 16 subnets with 14 usable IPs for hosts that is because one is for subnet and one for broadcas in that subnet for example: 192.168.1.0/28 - subnet number 192.168.1.15 -broadcast number usable IPs for hosts - IPs between them that is 14
