What is the maximum number of subnets and hosts it can handle?
Any network with a subnet mask of 255.255. 248.0 will be a 21 (8+8+5) bit network having 11 (32–21) host bits. This network will have 2048 ( 2^11) hosts. Excluding the reserved Network and Broadcast addresses, there can be a maximum number of 2046 hosts.
How many usable subnets and hosts are available?
Subnet Cheat Sheet – 24 Subnet Mask, 30, 26, 27, 29, and other IP Address CIDR Network References
| CIDR | Subnet mask | # of usable IP addresses |
|---|---|---|
| /27 | 255.255.255.224 | 30 |
| /26 | 255.255.255.192 | 62 |
| /25 | 255.255.255.128 | 126 |
| /24 | 255.255.255.0 | 254 |
What is the maximum number of valid subnets and usable hosts per subnet that you can get from a class C using 255.255 255.224 as a subnet mask?
Mask 255.255. 255.0 has 16 bits for the subnet and 8 bits of the host. Have possible 28 -2 hosts =254 which is enough.
How do you find the maximum subnet?
To calculate the number of possible subnets, use the formula 2n, where n equals the number of host bits borrowed. For example, if three host bits are borrowed, then n=3. 23 = 8, so eight subnets are possible if three host bits are borrowed. The table below lists the powers of 2.
What is the maximum number of usable subnets that you can create in class B network?
Example 6: The Class B 255.255. 255.128 subnet mask: 2-2=510 subnets.
What is the maximum number of hosts you can assign to any single subnet?
The 255 address (in binary notation, a host address of all ones) is used to broadcast a message to every host on a network. Just remember that the first and last address in any network or subnet can’t be assigned to any individual host. You should now be able to give IP addresses to 254 hosts.
How many subnets can be created?
Having 5 bits available for defining subnets means that we can have up to 32 (2^5) different subnets. It should be noted that in the past using subnet zero (00000—) and all-ones subnet (11111—) was not allowed.
How many subnets and hosts per subnet can you get from the network?
So 1024 subnets are available. Each subnet will have 6 bits for hosts. 2^6 = 64. We subtract 2 for the first and last address in the subnet, so 62 host addresses are available per subnet.
How many subnets and hosts per subnet can you get from the network 192.168 200.0 29?
You need to divide the 192.168. 200.0 network into 7 subnets. Each subnet needs at least 18 host addresses.
What are the valid subnets?
The normal understanding of a ‘valid’ subnet address is one in which the address quoted is the lowest possible in the specified range. Hence a /26 (64 addresses) would end with a multiple of 64, and a /27 would end with a multiple of 32.
How many subnets are there?
Total number of subnets: Using the subnet mask 255.255. 255.248, number value 248 (11111000) indicates that 5 bits are used to identify the subnet. To find the total number of subnets available simply raise 2 to the power of 5 (2^5) and you will find that the result is 32 subnets.
How do you find the maximum number of hosts?
and on the question of maximum number of hosts then one must subtract the network ID from the local Broadcast address. Using the formula (2^11)-2 then we shall get 2046 to be the maximum number of hosts.
