You can create: 1 subnet containing 64 addresses (/26) 2 subnets containing 32 addresses (/27) 4 subnets containing 16 addresses (/28)
.
Similarly one may ask, how many subnets are possible?
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.
Also Know, how many subnets are in a class C? Subnetting Class C Addresses 1.0. You need to create 5 sub networks each network has a maximum of 10 hosts. We can only use the first 8 bits for out subnets as these 8 bits have been allocated as host addresses. So Subnet masks of 255.255.
Similarly, how many subnets are in a 24?
Deducting 224 from 256 gives us 32. So the available subnets are 0,32, 64, 96, 128, 160, 192, 224. Exam Alert: Sometime back Cisco used to discard the first and the last subnet, also called subnet zero.
2-3 Subnetting.

What is the format of IP address?
The format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be zero to 255.What is a 16 subnet?
For the 16 subnet, the valid host range you can assign on a network is 17-30 because the subnet number is 16 and the broadcast address is 31. For the 32 subnet, the valid host range is 33 to 46 because the subnet number is 32 and the broadcast address is 47.How many IP addresses are in a 29?

What is a 255.255 255.0 subnet?
A subnet mask of 255.255. 255.0 allows for close to 256 unique hosts within the network (since not all 256 IP addresses can be used). This is the default subnet mask used by Class B networks and provides up to 65,536 IP addresses (256 x 256). The largest Class A networks use a subnet mask of 255.0.What is 24 subnet mask?
An IPv4 subnet mask consists of 32 bits; it is a sequence of ones (1) followed by a block of zeros (0). The following example shows the separation of the network prefix and the host identifier from an address (192.0. 2.130) and its associated /24 subnet mask (255.255. 255.0).How many 24 subnets are in a 16?

What is Subnet example?
A portion of a network that shares a common address component. On TCP/IP networks, subnets are defined as all devices whose IP addresses have the same prefix. For example, all devices with IP addresses that start with 100.100. 100.How many IP addresses are in a 8?
The “8” denotes that there are 24 bits left over in the network to contain IPv4 host addresses: 16,777,216 addresses to be exact.What exactly is a subnet?
A subnet is a logical partition of an IP network into multiple, smaller network segments. It is typically used to subdivide large networks into smaller, more efficient subnetworks. Each subnet allows its connected devices to communicate with each other, and routers are used to communicate between subnets.How many IP's are in a 30?

What is default gateway IP?
Ad. In the networking world, a default gateway is an IP address that traffic gets sent to when it's bound for a destination outside the current network. On most home and small business networks—where you have a single router and several connected devices—the router's private IP address is the default gateway.How many addresses are in a 24?
