What you are asking for is a bit uncommon, so to get number of subnet bits for hosts, you have to take maximum number of bits (32) and subtract the network bits (27 in this case), so u get 32-27 = 5.... Next, we have the two largest networks to find the subnet for: network C and D, 25 hosts each. Let’s find the number of host bits we need: 2^H – 2 = 25, H = 5.

number of bytes transmitted is 232+194,156,028=3,591?107 bits. Thus it would Thus it would take 3,591 seconds = 59 minutes to transmit the file over a 10~Mbps link.... Number of hosts = 2^y-2 where y is the number of "off" bits or 0's 256 – subnet mask = base number or first subnet (add this number to itself to find remaining subnets)

IP subnet basics . Ip addresses are 32 bits (4 octets or 4 x 8 = 32) IP addresses are constructed in classes based on 1 st octet number. Each class has different network id and host id fields... Next, we have the two largest networks to find the subnet for: network C and D, 25 hosts each. Let’s find the number of host bits we need: 2^H – 2 = 25, H = 5.

**4 Subnetting and Bit Borrowing for Hosts and Subnets**

are used for subnetting with a total of 9 subnet bits, 8 bits in the third octet and 1 bit in the fourth octet. Since there is only 1 bit in the fourth octet, the bit is either off or on-... (The number of masked bits in the 4 th octet is 3, the number of unmasked bits in the 4 th octet is 5, this is the last octet we borrowed from. This means that the value of the 4 th octet increases by the increment value.)

## How To Find Number Of Bits From Number Of Hosts

### for the network portion (as represented by the subnet mask) gives you the number of bits used for hosts. Using our example above, the subnet mask 255.255.192.0 is equivalent to /18 in prefix notation.

- To find the correct answers to these types of questions, you first need to decide how many subnet bits and host bits you need to meet the requirements. Basically, the number of hosts per subnet is 2 x - 2, where x is the number of host bits in the address.
- The number of 0s at the end of the mask always defines the number of hosts on any network or subnet. There is a simple mathematical formula that defines how many IP addresses are available to be assigned to hosts.
- To calculate the number of hosts we should use the simple formula of (2^[bits in netmask] - 2 ). Here as the subnet mask is 24 we get the number of addressable bits as 8(32 - 24). Thus the number of hosts are (2^8(=256) -2)=254 unique host IPs.
- The more bits you borrow, the more subnets you can have, but this means fewer hosts per subnet. However, with a Class A mask, you have 24 bits to manipulate, so this isn’t typically a problem.
