How many subnets are in a class B?
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 |
What is the maximum number of hosts one can use for each subnet using class B addressing?
IP subnetting
| Subnet Mask | Number of Supported Hosts per Network | |
|---|---|---|
| Class A | 255.0.0.0 | Over 16 million |
| Class B | 255.255.0.0 | Over 16 thousand |
| Class C | 255.255.255.0 | 254 |
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 many hosts can a class B network have?
Table 2-1 IP Addresses Available to Internet Hosts
| Address Class | First Octet Range | Number of Hosts Per Network |
|---|---|---|
| Class A | 0 to 126 | 16,777,214 |
| Class B | 128 to 191 | 65,534 |
| Class C | 192 to 223 | 254 |
How many subnets can a Class B network have?
It would give us 5 bits but since it is Class B, we’ve got those extra 8 bits. 5 plus 8 gives us 13 bits and 2 to the power of 13 is going to allow a total of 8,192 subnets. For the IP address, 135.15.10.138/29, what would be the network address, the broadcast address, and the range of valid IP addresses?
What is the IP address of a Class B network?
For our first example, we’ve been allocated a Class B network with an IP address of 135.15.0.0/16. If we subnet that into /29 subnets, we’re going to have 3 bits for host addressing.
How to split a network into 32 subnets?
Now we know we need to borrow 5 bits from the host to create a 32 subnets Divide Network and Host Portion with the New Subnet Mask So if you convert the Net Mask into Binary you will get a New Net Mask 255.255.255.0 Step 4 Now you got your new Net mask ,
How many addresses do I need for each subnet?
If we take all these addresses and divide them equally into 8 different subnets we still keep the total number of original addresses, but we have now split them into 8 subnets with 32 addresses in each. Each new subnet needs to dedicate 2 addresses for the subnet and broadcast address within the subnet.
