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.

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.


Divide 192.168.1.024 into 6 subnets?

To divide the network 192.168.1.0/24 into 6 subnets, we need to determine the subnet mask that accommodates at least 6 subnets. Using a /26 subnet mask (which allows for 4 subnets), we can go to /25 (which allows for 2 subnets) or /27 (which allows for 8 subnets). With a /27 subnet mask (255.255.255.224), we can create 8 subnets, each with 30 usable IP addresses. The resulting subnets would be: 192.168.1.0/27, 192.168.1.32/27, 192.168.1.64/27, 192.168.1.96/27, 192.168.1.128/27, and 192.168.1.160/27.


Where do you get your subnet number from?

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.


How many subnets are required to support the network shown?

To determine the number of subnets required, you need to know the number of distinct network segments or groups of devices that require separate IP address ranges. Each subnet typically supports a specific number of hosts, and the total demand for hosts across all segments will dictate how many subnets are necessary. If you provide more specific details about the network layout or the number of devices, I could give a more precise answer.


How do you configure VLSM?

To configure Variable Length Subnet Masking (VLSM), you start by determining your network requirements, including the number of subnets and hosts needed for each subnet. Next, you allocate a larger subnet, then divide it into smaller subnets using different subnet masks based on the specific needs of each segment. Assign IP addresses accordingly, ensuring that each subnet has a unique network address and subnet mask. Finally, update routing protocols if necessary to accommodate the new subnets.


How many valid subnets do you get if you borrow 3 bits?

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.
