How many hosts in each subnet can be created?
we can calculate how many bits will be required so that each subnet has 30 host addresses. 25 -2 =30, so 5 bits atleast must be available for host addressing and the remaining can be borrowed to create subnet addresses.
How many subnets can be created?
Each subnetwork could potentially support up to 30 host addresses. Since you now have four bits to make subnets with, you only have four bits left for host addresses. So in this case you can have up to 16 subnets, each of which can have up to 16 host addresses (14 of which can be assigned to devices).
How many valid hosts you can create if the subnet mask is 28?

What is the maximum number of subnet?
Maximum number of subnets = 2^6-2 =62. Note that 2 is subtracted from 2^6. The RFC 950 specification reserves the subnet values consisting of all zeros (see above) and all ones (broadcast), reducing the number of available subnets by two. Maximum number of hosts is 2^10-2 = 1022.
How many hosts are in a class C 29 mask?
For Class C Networks
| network | network mask | total hosts |
|---|---|---|
| /count | ||
| 28 | 255.255.255.240 | 224 |
| 29 | 255.255.255.248 | 192 |
| 30 | 255.255.255.252 | 128 |
What is the effective number of hosts for a subnet?
Subnetting Example. A host portion with all zeros is network number itself, and a host portion with all ones is reserved for broadcast on that subnet, leaving the effective number of hosts to 4194302 (2 22 – 2), as shown in the fourth column. An exception to this rule is 31-bit prefixes, marked with an asterisk ( * ).
How to create a subnet in Class C?
There are a couple of ways to create subnets. In this article we will subnet a class C address 192.168.0.0 that, by default, has 24 subnet bits and 8 host bits. 1. How many subnets do we need? 2x = number of subnets. x is the number of 1s in the subnet mask.
How to increase the number of IP addresses on a subnet?
This example yields a network of 254 hosts that occupy the range of addresses from 192.168.1.1 to 192.168.1.254. The scope you created has the following properties: To increase the number of addresses available to clients, you can change either the Start Address or End Address as far as 1 and 254, respectively.
How many subnets do you need in CCNA?
1. Since we need only two subnets, we need 2 1 subnet bits. In our case, this means that we will take one bit from the host part. Here is the calculation: First, we have a class C address 192.168.0.0 with the subnet mask of 24. Let’s convert them to binary: We need to take a single zero from the host part of the subnet mask.
