Let’s discuss the question: how many subnets are needed for the following topology. We summarize all relevant answers in section Q&A of website Abettes-culinary.com in category: MMO. See more related questions in the comments below.
How many subnets can you have?
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 are in a 24?
| CIDR | Subnet mask | # of IP addresses |
|---|---|---|
| /26 | 255.255.255.192 | 64 |
| /25 | 255.255.255.128 | 128 |
| /24 | 255.255.255.0 | 256 |
| /23 | 255.255.254.0 | 512 |

How many subnets and hosts per subnet would be available?
The maximum number of available hosts is 4094. You cannot, of course, use the first or last IP in a subnet (e.g. 10.0. 0.0 and 10.0. 15.255) for hosts as these are required for other purposes.
How many subnets and hosts per subnet can you?
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.
What is a 31 subnet?
31-bit Subnet Mask (/31)
A 31-bit subnet mask is often used for an interface that is the endpoint of a point-to-point network. The use of 31-bit subnet masks for IPv4 point-to-point links is described in RFC 3021. For 192.168.0.0. Router A is connected via Fast-ethernet 0/0 having ip 192.168.
What is a 27 subnet?
/27 — 8 Subnets — 30 Hosts/Subnet. Network # IP Range. Broadcast. .0.

What is a 255.255 255.0 subnet?
A class C network would have a subnet mask of 255.255. 255.0 which means that 24 bits are used for the network. In CIDR notation this is designated by a /24 following the IP address.
How many bits does IPv4 have?
IPv4 addresses are 32-bit numbers that are typically displayed in dotted decimal notation. A 32-bit address contains two primary parts: the network prefix and the host number. All hosts within a single network share the same network address. Each host also has an address that uniquely identifies it.
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.
What is IP NAT?
NAT stands for network address translation. It’s a way to map multiple local private addresses to a public one before transferring the information. Organizations that want multiple devices to employ a single IP address use NAT, as do most home routers.
How many subnets are in a network?
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.

How do you calculate the number of networks in a class?
The total number of networks a class address may have is calculated by subtracting the number of bits in the subnet mask from the number of bits used to determine which class of network it is. For example, a class A network has an 8-bit subnet mask.
How many bits should you borrow to create the required number of subnets?
For every host-bit we borrow we can double the number of subnets we can create, so by borrowing 2 host bits we can create 4 subnets. Every host bit you “borrow” doubles the amount of subnets you can create. Calculate it from binary to decimal: 128+64 = 192. The new subnet mask will be 255.255.
