What else can I help you with?
If you have a class b network 172.121.225.0 and you want to do subnetting of 130 networks how many bits are used for subnetting?
As we are using a class B network for the Subnetting and we have to make a total of at least 130 subnetworks...so, class B default subnet mask is 255.255.0.0 or 16 bits for networkingand we have to make 130 sunets. so it will come under the block size of 256 or we need 8 bits more to make 130 subnets.so our answer is 16+8=24ie, we will use subnet mask of 255.255.255.0 for this class B address.
How is math used in computer networking?
In computer networking Math and binary operation are used in calculating subnet masks or in subnetting or in supernetting etc.
What is the purpose of Subnetting?
Definition: A subnet is a logical grouping of connected network devices. Nodes on a subnet tend to be located in close physical proximity to each other on a LAN.The pourpose of subnetting is not to provide extra addresses, but to keep network data separated to prevent congestion.
Why is VSLM not used in CCNA 1?
VSLM (Variable Length Subnet Masking) is not covered in CCNA 1 primarily because the course focuses on foundational networking concepts, including basic IP addressing and subnetting. VSLM is a more advanced topic that involves optimizing subnetting for more efficient IP address use, which is typically introduced in later courses when students have a stronger grasp of networking principles. The emphasis in CCNA 1 is on understanding the basics before delving into more complex addressing techniques.
What is the motivation behind using a custom subnet mask versus the default subnet mask?
A default subnet mask gives you classful addressing on octet boundaries. A non-default subnet mask implies that you are subnetting a larger network into several smaller ones.
Breaking a network into smaller parts is called?
segmentation
The process of dividing a larger network into smaller ones is called?
Subnetting Bodry
How do devices interpret subnetting information if subnetting is used on a LAN?
Devices interpret subnetting information on a LAN by determining where the traffic originated and routing it to the appropriate area. By creating subnets, it is possible to have segregated areas of a network.
You might never want to use subnetting if?
There is no need to use subnetting if you have no wish to further divide up your network into smaller, logical networks.
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 are the disadvantage of subnetting?
Loose of ip address
What is the smallest number of host bits that must be left in the host field when subnetting an IP address?
one number of host bits must be left when you doing subnetting.
How many bits of subnetting does the ip address 10.15.8.0.255.255.240.0 have?
12
How does subnetting affect a network?
Subnetting allows you to create multiple local networks within a network. For more details use this site: http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a00800a67f5.shtml
What is subnating?
Subnetting is the practice of dividing a network into two or more networks.
Which option represents a network with 8 bits of subnetting?
172.16.1.0 24
How many subnets are provided in a network with 7 bits of subnetting?
126
