What subnet mask is 192?
Subnetting and Masks
| IP Address | 192 | 168 |
|---|---|---|
| Subnet Mask | 255 | 255 |
| Subnet Mask (in Binary) | 11111111 | 11111111 |
How many subnets can you get from the network 192.168 93.0 26?
Subnetting Questions
| Question | Answer |
|---|---|
| You are designing a subnet mask for the 192.168.109.0 network. You want 2 subnets with up to 110 hosts on each subnet. What subnet mask should you use? | 255.255.255.128 |
| How many subnets and hosts per subnet can you get from the network 192.168.93.0/26? | 4 subnets and 62 hosts |
How do you calculate the number of hosts and subnets?
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 subnets and hosts per subnet can you get from the network 192.168 100.0 26?
100.0/26 indicates that the network is 192.168. 100.0 with a subnet mask of 255.255. 255.192 so Symetrix support would know this subnet mask creates 4 subnets with 64 total IP addresses of which 2 are reserved for the network and broadcast addresses, so there are 62 available host IP addresses per network.
How many host addresses are available in the 128 network?

How many hosts are in a 8 subnet?
Subnet Cheat Sheet – 24 Subnet Mask, 30, 26, 27, 29, and other IP Address CIDR Network References
| CIDR | Subnet mask | # of IP addresses |
|---|---|---|
| /10 | 255.192.0.0 | 4,194,304 |
| /9 | 255.128.0.0 | 8,388,608 |
| /8 | 255.0.0.0 | 16,777,216 |
| /7 | 254.0.0.0 | 33,554,432 |
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 172.25 0.0 23?
4096 subnets and 14 hosts. How many subnets and hosts per subnet can you get from the network 172.22. 0.0 255.255.
How do you calculate the number of hosts?
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 the purpose of a subnet mask in IPv4 addressing?
A subnet mask is used to divide an IP address into two parts. One part identifies the host (computer), the other part identifies the network to which it belongs.
What is the difference of IP address from subnet mask?
We always reserve an IP address to identify the subnet and another one to identify the broadcast address within the subnet. Subnet mask divides the IP address into a network address and host address, hence to identify which part of IP address is reserved for the network and which part is available for host use.
How many IPv4 addresses are available to be assigned to hosts on a network?
Each of the 126 Class A addresses has almost 17 million possible host addresses that make up about half of the entire IPv4 address space. Recall that the network address 127.0. 0.1 is reserved for the local loopback address, which is why Class A addresses stop at 126.0. 0.0 and Class B addresses start at 128.0.
What is the minimum number of hosts required for subnetting?
The requirement is to perform subnetting such that we create as many subnets as we can with 30 hosts in each subnet. Our First step will be to determine how many bits do we need to borrow from the host portion such that the requirement of minimum 30 hosts per subnet is fulfilled. Using the formula below
How many subnets are there in a Class B network?
First, 130.4.102.1 is in a Class B network, so there are 16 network bits. A subnet mask of 255.255.255.0 has only eight binary 0s, implying 8 host bits, which leaves 8 subnet bits in this case.
What is the default subnet mask for a Class B address?
Class B addresses use a default mask of 255.255.0.0 Given subnet mask = 255.255.255.240 = /28 = 255. 255. 11111111. 11110000 Subnet Bits = 12 , corresponds to 2^12 = 4096 subnets. Host Bits = 4 , corresponds to (2^4-2) = 14 hosts. 4096 subnets and 14 hosts.
What is the size of the subnet in the address?
The size of the subnet part of the address is what’s left over, or 8 bits. Two other examples with easy-to-convert masks might help your understanding. Consider address 130.4.102.1, with mask 255.255.255.0. First, 130.4.102.1 is in a Class B network, so there are 16 network bits.
