How do you calculate subnet range?
How do you calculate subnet range?
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 I calculate my IP address range?
It’s pretty easy. If you break down the IP given to you to binary, the network address is the ip address where all of the host bits (the 0’s in the subnet mask) are 0,and the last address, the broadcast address, is where all the host bits are 1. That’s the best explanation how to calculate those ranges I read so far.
What is the subnet mask corresponding to a CIDR value of 14?

What is subnet range?
Each VPC network consists of one or more IP address range called subnets. Subnets are regional resources, and have IP address ranges associated with them. In Google Cloud, the terms subnet and subnetwork are synonymous.
What IP addresses are in a range?
Summarizing the differences between private and public IP addresses
| Public IP address | Private IP address |
|---|---|
| Not free | Free |
| Any number not included in the reserved private IP address range Example: 8.8.8.8. | 10.0.0.0 — 10.255.255.255; 172.16.0.0 — 172.31.255.255; 192.168.0.0 — 192.168.255.255 Example: 10.11.12.13 |
What is a subnet range?
What is the number of hosts in a 14 network?
Subnet Cheat Sheet – 24 Subnet Mask, 30, 26, 27, 29, and other IP Address CIDR Network References
| CIDR | Subnet mask | # of IP addresses |
|---|---|---|
| /14 | 255.252.0.0 | 262,144 |
| /13 | 255.248.0.0 | 524,288 |

How is host range calculated?
You can figure out how many hosts you can have in your subnet by subtracting the number of network bits from the number of total bits: in other words, 32 total bits, minus the number of network bits.
What is the range of class B IP address?
Designing Your IP Addressing Scheme
| Network Class | Byte 1 Range | Byte 3 Range |
|---|---|---|
| A | 0-127 | 1-254 |
| B | 128-191 | 1-254 |
| C | 192-223 | Preassigned by Internet |
What is a class B network?
A class B network is a type of network in the now-defunct classful networking architecture. The classful networking architecture defined a range of network classes: A, B, C, D and E. Class B networks have IP addresses between 128.0. 0.0 and 191.255. 255.255.
What subnet mask does the prefix 14 represent?
Understanding CIDR Subnet Mask Notation
| Subnet Mask | CIDR Prefix | Total IP Addresses |
|---|---|---|
| 255.255.0.0 | /16 | 65,536 |
| 255.254.0.0 | /15 | 131,072 |

| 255.248.0.0 | /13 | 524,288 |
What is valid host range?
What is the valid host range of each subnet? Answer: The valid hosts are the numbers between the subnet number and the mask. For the 64 subnet, the valid host range is 64-126. For the 128 subnet, the valid host range is 129-190.
How is network mask calculated?
The first and last addresses are reserved: the first to identify the network and the last to be used as the broadcast address.
- Find host range.
- Convert to binary.
- Calculate the total number of hosts per subnet.
- Calculate the number of subnets.
- Verify the total number of subnets.
What is the valid host range for the 255.255 255.248 subnet?
10.17 255.255. 255.248. What are the subnet, broadcast address, and host range that this host is a member of? The answer is: 256-248=8, 16, 24.
