How many subnets can you create if you borrow 10 bits of a class B network quizlet?
To support a minimum of 1000 subnets you would need to borrow 10 bits. 10 bits plus 16bits (from the network) = 26. A subnet design uses Class A network 10.0. 0.0, and the engineer must choose a single mask to use through the network.
How many hosts can be on each subnet?
Hosts per subnet: 3 bits are left to identify the host therefore the total number of hosts per subnet is 2 to the power of 3 minus 2 (1 address for subnet address and another one for the broadcast address)(2^3-2) which equals to 6 hosts per subnet.
How do you calculate the number of hosts in a subnet?
To calculate the number of possible hosts per subnet, use the formula 2h – 2, where h equals the number of host bits. The reason two addresses must be subtracted is because of the network address and the broadcast address.
How many hosts are in a bit?
There are 16 host bits because, when you convert 255.255. 0.0 to binary, there are 16 binary 0sthe last 16 bits in the mask.
How Many Hosts and How Many Subnets.
| Step | Example | Rules to Remember |
|---|---|---|
| Number of host bits | 16 | Always defined as number of binary 0s in mask |
| Number of subnet bits | 8 | 32 – (network size + host size) |
How many hosts are in a 25 subnet?
Subnet Mask Cheat Sheet
| Addresses | Hosts | |
|---|---|---|
| / 25 | 128 | 126 |
| / 24 | 256 | 254 |
| / 23 | 512 | 510 |
| / 22 | 1024 | 1022 |
What is the maximum number of hosts in a 19 subnet?
C. A CIDR address of /19 is 255.255. 224.0. This is a Class B address, so that is only 3 subnet bits, but it provides 13 host bits, or 8 subnets, each with 8,190 hosts.
How many hosts are in a class C 29 mask?
For Class C Networks
| network | network mask | total hosts |
|---|---|---|
| /count | ||
| 28 | 255.255.255.240 | 224 |
| 29 | 255.255.255.248 | 192 |
| 30 | 255.255.255.252 | 128 |
How many subnets can you create if you borrow 3 bits in a Class C network?
8 subnets
If you look at the design requirement of 30 hosts per network, you will discover that I only need 5 bits in the host ID portion of a Class C network to satisfy my requirement. By borrowing 3 bits, I can create 8 subnets: 192.168.
How many host are there?
Total IPv4 Network Host Addresses
For our example of a /21 (network mask 255.255. 248.0 ) network, there are 11 host bits ( 32 address bits 21 network bits = 11 host bits ). That means there are 2048 total host addresses in a /21 IPv4 network ( 2^11 = 2048 ).
How many subnetworks and hosts are available per subnet If you apply a 27?
Class A
| Network Bits | Subnet Mask | Number of Hosts |
|---|---|---|
| /27 | 255.255.255.224 | 30 |
| /28 | 255.255.255.240 | 14 |
| /29 | 255.255.255.248 | 6 |
| /30 | 255.255.255.252 | 2 |
What is host number?
A host (also known as “network host”) is a computer or other device that communicates with other hosts on a network.On a TCP/IP network, each host has a host number that, together with a network identity, forms its own unique IP address.
How do I find out how many host addresses I have?
The formula to determine how many hosts can operate on a network is 2n-2, where n is the number of 0 bits in the subnet mask. A subnet mask has 32 bits. If the CIDR notation is /27 it indicates that there are 5 bits left to create subnets.
What is host bit?
Host bits are the portion of an IP address that identify a specific host in a subnet. The subnet mask determines how much of the address is used for network bits and host bits.
How many bits must be borrowed?
Explanation: Each network that is directly connected to an interface on a router requires its own subnet. The formula 2n, where n is the number of bits borrowed, is used to calculate the available number of subnets when borrowing a specific number of bits.
How many hosts are in a 224 subnet?
224 subnet mask. This mask permits up to 8 subnets with enough host addresses for 30 hosts per subnet.
What is a 255.255 254.0 subnet?
255.255.254.0 = 1 bit less than 24 bits mask, so (256 x 2) – 2 hosts = 510. And to know if an ip address is good or not regarding a certain subnet..i do the following: Is 192.168. 1.64 – 255.255.
What is the valid host range for the 255.255 255.248 subnet?
IPv6 Subnet Calculator
| Prefix size | Network mask | Usable hosts per subnet |

| /27 | 255.255.255.224 | 30 |
| /28 | 255.255.255.240 | 14 |
| /29 | 255.255.255.248 | 6 |
| /30 | 255.255.255.252 | 2 |
How many subnets and hosts are provided by the network address of 172.16 0.0 19?
Solution(By Examveda Team)
This is a Class B address, so that is only 3 subnet bits, but it provides 13 host bits, or 8 subnets, each with 8,190 hosts.
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.
