When you borrow 3 bits from the host portion of an IP address, you can create (2^3 = 8) valid subnets. However, one subnet is reserved for the network address and another for the broadcast address, leaving you with 6 usable subnets. Thus, by borrowing 3 bits, you obtain 6 valid subnets for use.
What else can I help you with?
How many bits do you need to borrow in a class C subnet masks to accommodate 18 networks?
Borrow 5 bits (for 30 subnets total).
In a class A how many subnet bits are needed to make at least 365 useable hosts or subnets?
You would need at least 9 bits to borrow. Since 8 bits gives only 255 the additional bit will get you 256. Adding 256 + 128 gives you at least 384 subnets or hosts.
How Given a Class C network 200.1.1.0 We want 5 subnets each with 30 hosts on it. How many bits to borrow How many bits to leave What is the subnet mask ( in dot notation and in CIDR notation)?
Given a Class C network: 200.1.1.0 We want 5 subnets, each with 30 hosts on it. How many bits to borrow ? How many bits to leave? What is the subnet mask? ( in dot notation and in CIDR notation)
How many bits are borrowed from a class B host address to create 30 new subnets?
5 bits are necessary to create up to 30 subnets.
How do you use 172.16.0.0 to create 6 subnets?
To create 6 subnets from the IP address 172.16.0.0, you need to determine how many bits to borrow from the host portion of the address. Since 2^3 = 8, borrowing 3 bits allows for 8 subnets, which is sufficient for your requirement of 6. This results in a subnet mask of 255.255.248.0 (or /21), providing each subnet with 2046 usable host addresses. The subnets would range from 172.16.0.0/21 to 172.16.7.0/21.
How many bits must be reallocated from host ID to network ID to createe 16 subnets?
you need to reallocate 4 bits to creat 16 subnets. how do I get that? easy! 2 to the power of 4 gives us 16 subnets.
How many host bits are borrowed if four subnets are created?

How many subnets are provided in a network with 7 bits of subnetting?
126
How many bits would you borrow to subnet 192.168.50.0 do to ten networks?
To create ten networks from the 192.168.50.0 subnet, you need to determine how many bits to borrow from the host portion. Since 2^n must be at least 10 to accommodate the networks, you need to borrow 4 bits (since 2^4 = 16, which covers the requirement). This means the new subnet mask will be /28 (or 255.255.255.240), allowing for 16 subnets with 14 usable hosts each.
How many bits can you borrow from 192.168.1.0?
It is possible to borrow a possible 3 bits from 192.168.1.0.
How many subnets and hosts per subnet can you get from the network 172.16.0.0?
There are 16 bits available; it is up to you how many of those bits you reserve for the subnet, and how many for the individual hosts within each subnet.
How many subnets are available in prefix?
It depends on how many bits you are using for the network prefix. The formula is 2n - 2 for the number of subnets available in a prefix, or 2n if you allow the use of the 0th subnet.
