| Prefix size | Network mask | Usable hosts per subnet |
|---|---|---|
| /29 | 255.255.255.248 | 6 |
| /30 | 255.255.255.252 | 2 |
| /31 | 255.255.255.254 | 0 |
| /32 | 255.255.255.255 | 0 |
How do you split networks into subnets?
In this case, you divide your network into four subnets by using a subnet mask that makes the network address larger and the possible range of host addresses smaller. In other words, you are ‘borrowing’ some of the bits used for the host address, and using them for the network portion of the address.
Which class does the network address 172.16 0.0 belong to?
class B
The 172.16. 0.0/12 private network can be interpreted either as a block of 16 class B network IDs or as a 20-bit assignable address space (20 host bits) that can be used for any sub-netting scheme within the private organization. The 172.16.
What is the subnet mask of 172.16 0.0 18?
192.
| Subnet | Network Address | Broadcast Address |
|---|---|---|
| 172.16.0.0/18 | 172.16.0.0 | 172.16.63.255 |
| 172.16.64.0/18 | 172.16.64.0 | 172.16.127.255 |
| 172.16.128.0/18 | 172.16.128.0 | 172.16.191.255 |
| 172.16.192.0/18 | 172.16.192.0 | 172.16.255.255 |
What is a 32 subnet used for?
Generally speaking, /32 means that the network has only a single IPv4 address and all traffic will go directly between the device with that IPv4 address and the default gateway. The device would not be able to communicate with other devices on the network.
How do subnets work?
Subnetting works by applying the concept of extended network addresses to individual computer (and another network device) addresses. An extended network address includes both a network address and additional bits that represent the subnet number.
How do you calculate subnets and hosts per subnet?
This means that to create at least 18 subnets, 5 host bits must be borrowed. 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 need to be created from the 172.16 0.0 16 network?
16 subnets
0.0/16 into 16 subnets with the mask 255.255. 240.0, i.e. 172.16….2.3 Subnets.
| Network Number | First Address | Last Address |
|---|---|---|
| 172.16.0.0 | 172.16.0.1 | 172.16.15.254 |
| 172.16.16.0 | 172.16.16.1 | 172.16.31.254 |
| 172.16.32.0 | 172.16.32.1 | 172.16.47.254 |
| 172.16.48.0 | 172.16.48.1 | 172.16.63.254 |
What is the subnet mask 172.16 0.0 16?
IP Subnet Calculator
| CIDR block | IP range (network – broadcast) | Subnet Mask |
|---|---|---|
| 172.16.0.0/17 | 172.16.0.0 – 172.16.127.255 | 255.255.128.0 |
| 172.16.0.0/16 | 172.16.0.0 – 172.16.255.255 | 255.255.0.0 |
| 172.16.0.0/15 | 172.16.0.0 – 172.17.255.255 | 255.254.0.0 |
| 172.16.0.0/14 | 172.16.0.0 – 172.19.255.255 | 255.252.0.0 |
How many subnets and host can you get from the network 172.16 0.0 18?
0.0/18 – why 4 subnets.
What does it mean to subnett network 172.16.0?
If you have network 172.16.0.0, then you know that its natural mask is 255.255.0.0 or 172.16.0.0/16. Extending the mask to anything beyond 255.255.0.0 means you are subnetting. You can quickly see that you have the ability to create a lot more subnets than with the Class C network.
What kind of address is 172.16.0.0?
Since the subnet makes is explicitly stated, both of those addresses are classless address. If you only had the address and no prefix, 172.16.0.0 would be a class B address. The upper bits of the first octet would represent the class and imply the prefix of /16.
What does subnetting mean in network address bit?
Any address bits which have corresponding mask bits set to 1 represent the network ID. Any address bits that have corresponding mask bits set to 0 represent the node ID. Subnetting allows you to create multiple logical networks that exist within a single Class A, B, or C network.
Can a subnet have more than one host address?
A subnet mask of 255.255.255.255 (a /32 subnet) describes a subnet with only one IPv4 host address. These subnets cannot be used for assigning address to network links, because they always need more than one address per link. The use of /32 is strictly reserved for use on links that can have only one address.
