For more efficient usage of IP addresses.
Instead of an ISP assigning a customer an entire class C of IPs (255 addresses), they can assign them a smaller subnet of 8 or 16 addresses instead, only as many as the customer needs.

∙ 15y agoWith the advent of internet, IP based networks became hugely popular. Due to this available IP Addresses depleted at huge rate. To overcome this shortage concept of Subnetting was introduced.
Subnetting removes the classification of IP addresses according to classes &helps in creating furhterSubnetworks from Existing range ofaIP network range.
For e.g A class B IP address can be broken down into further smaller networks with 254 hosts each.

∙ 15y ago"Subnetting" creates Layer 3 barriers between Layer 2 networks. Layer 2 networks rely somewhat on broadcasts, which can flood the network and overwhelm it if there are too many. Subnetting allows you to reduce the scope of the Layer 2 network and keep broadcasts under control.

- Keep certain network traffic in its own network
- Keep certain protocols (legacy) in its own network
- Easier to troubleshoot problems
- Provides an element of security by keeping traffic in its own network/segment

∙ 9y agoSubnet means dividing a network in to smaller sub networks. A subnet is like a subset of a network. To reduce overhead from network , a network is divided in to subnets.

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.
What is a static length subnet mask?
That probably refers to a situation where a larger network was divided into smaller subnets, but all subnets have the same size - as opposed to VLSM (variable length subnet masks), where subnets can have different sizes.That probably refers to a situation where a larger network was divided into smaller subnets, but all subnets have the same size - as opposed to VLSM (variable length subnet masks), where subnets can have different sizes.That probably refers to a situation where a larger network was divided into smaller subnets, but all subnets have the same size - as opposed to VLSM (variable length subnet masks), where subnets can have different sizes.That probably refers to a situation where a larger network was divided into smaller subnets, but all subnets have the same size - as opposed to VLSM (variable length subnet masks), where subnets can have different sizes.
Where do you get your subnet number from?
You (the network administrator) decide what subnet you need to use, depending on the available IP addresses, and how you want to divide your network into subnets (in case you use subnets).You (the network administrator) decide what subnet you need to use, depending on the available IP addresses, and how you want to divide your network into subnets (in case you use subnets).You (the network administrator) decide what subnet you need to use, depending on the available IP addresses, and how you want to divide your network into subnets (in case you use subnets).You (the network administrator) decide what subnet you need to use, depending on the available IP addresses, and how you want to divide your network into subnets (in case you use subnets).
How many /64 subnets are available in a /48 prefix?
There are 65,536 subnets available in an IPv6 /48 block.
What gateway interprets its outbound request to other subnets and then interprets its inbound requests from other subnets is called?
Default Gateways
Why should you create subnets?
Subnets allow to isolate traffic within a subnet. It is beneficial not only from security perspective but also from performance.
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.
What information is required prior to dividing a netowrk into subnets?
network class network address number of subnets required number of host per subnet
Does subnetting separate a network into multiple logical defined segments or subnets?
Yes. Subnetting separates a network into multiple logically defined segments, or subnets.

What does it mean to borrow 4 bits for subnets?
When you borrow bits for a subnet you are intruding into the client portion of an IP address. As a result, you will lose clients in your network because the "borrowed" portion becomes the extended network prefix. This allows you to separate your bigger network into smaller, logical networks (subnets). The number of bits borrowed will indicate the total number of smaller subnets that you can support in your network. In each case, regardless of class of address, borrowing 4 bits gives a total of 14 subnets (in the classical sense) and 16 subnets (in Cisco).
