How many subnets can a class B network have?

How many subnets can a class B network have?

There are nine bits for subnetting and seven bits for hosts. That is 510 subnets, each with 126 hosts. However, it is the most difficult mask to figure out the valid hosts for. Example 6: The Class B 255.255….Subnetting a Class B network address.

Subnet 64.0 128.0
broadcast 127.255 191.255

How many subnets are in a 8?

Class A

Network Bits Subnet Mask Number of Subnets
/8 255.0.0.0 0
/9 255.128.0.0 2 (0)
/10 255.192.0.0 4 (2)
/11 255.224.0.0 8 (6)

How many subnets can you create if you borrow 10 bits of a class B network?

(3) Ten bits remain as host bits: 210 = 1024, there will be 1022 useable hosts per subnet. (4) In dotted decimal format, the subnet mask will be 255.255. 252.0. 4.

How do you split networks into subnets?

Subnetting is the process of stealing bits from the HOST part of an IP address in order to divide the larger network into smaller sub-networks called subnets. After subnetting, we end up with NETWORK SUBNET HOST fields.

What is the default subnet mask of Class B?

255.255.0.0
Class B networks use a default subnet mask of 255.255. 0.0 and have 128-191 as their first octet.

How do I assign a Class B IP address?

Class B Network Numbers A class B network number uses 16 bits for the network number and 16 bits for host numbers. The first byte of a class B network number is in the range 128-191. In the number 129.144. 50.56, the first two bytes, 129.144, are assigned by the InterNIC, and comprise the network address.

What does 28 mean in ip address?

Answer: 28 is a subnet mask. IP address has 32 bits in total. 28 denotes network ID while rest of the bits (which are 4 bits) are used for hosts.

What is the maximum number of hosts per subnet?

You need to create 5 sub networks each network has a maximum of 10 hosts. We can only use the first 8 bits for out subnets as these 8 bits have been allocated as host addresses. So Subnet masks of 255.255. 255.224 and 255.255.

How many subnets are there in Class B?

That means, we can get two subnets if we do a single bit subnetting on a Class B network. Please refer below image. The network 172.16.0.0 is divided into two subnets, each subnet has 32,768 total IPv4 addresses and 32,766 usable IPv4 addresses.

How to create subnet mask for Class B network?

The range of ip address in a class B network is from 128.0.0.0 to 191.255.255.255. The subnet mask is fixed 255.255.0.0 for a classfull class B IP address. In this IP address we have only 16 bits for host. For creating subnetting we have only 16 bits to manipulate.

How to subnett a Class C network address?

This is exactly like subnetting a Class C network address, but the third octet is part of the subnet address. 256-255=1.0, 2.0, 3.0, etc. for the third octet. 256-192=64, 128, 192 for the fourth octet. For every valid subnet in the third octet, we get four subnets in the fourth octet: 0, 64, 128, and 192.

How many bits does a Class B network address have?

Class C network addresses only have eight bits to manipulate into subnets. However, a Class B has 16 bits to play with. This will allow more subnets with more hosts per subnet than a Class C network ever could.

The network 172.16.0.0 is divided into sixteen subnets, each subnet has 4,096 total IPv4 addresses and 4,094 usable IPv4 addresses (two IPv4 addresses are used in each subnet to represent the network address and the directed broadcast address ). The subnet mask to use for 4-bit subnetting for a Class B network is 255.255.240.0.

This is exactly like subnetting a Class C network address, but the third octet is part of the subnet address. 256-255=1.0, 2.0, 3.0, etc. for the third octet. 256-192=64, 128, 192 for the fourth octet. For every valid subnet in the third octet, we get four subnets in the fourth octet: 0, 64, 128, and 192.

Class C network addresses only have eight bits to manipulate into subnets. However, a Class B has 16 bits to play with. This will allow more subnets with more hosts per subnet than a Class C network ever could.

How to divide network IP addresses into subnets?

140.25.0.0 is a class B IP address and default subnet of Class B IP address is 16. In your case they have given you as 140.25.0.0/20. It basically means that you can create 16 Networks with the given IP address. So lets start. Network address : 140.25.0.0 Host IP address : 140.25.0.1 – 140.25.15.254 Default gateway : 140.25.15.255
