Determine the Internet addresses that describe each of the 3 subnets using FLSM

Question

Determine the Internet addresses that describe each of the 3 subnets using FLSM Determine the Internet addresses that describe each of the 3 subnets using VLSM. You must present the following information for each one of the 3 assigned subnets in the two scenarios (6 in total): Network address First usable address of the subnet Last usable address of the subnet Broadcast address for the subnet Prefix length Subnet mask You may consult the example that is provided under this Week’s materials. Please explain any assumptions or calculations you made to arrive to your final solution. Guideline on weekly Discussion: 1 initial posting by Thursday 11:59pm Central Time deadline. Please write your IP range and network sizes in the subject Line. Or at least, write them in the first lines of your posting. This way we will not have to go back to the top of the discussion thread to see if your calculations were done correctly. Also, please present one table for FLSM and one table for VLSM using the following format, this will help everyone to read your calculations: Subnet # Prefix Length Subnet Mask # Required Hosts Max # of Hosts Network Address First Address Last Address Broadcast Address 1 response to other students’ postings by Sunday 11:59pm Central Time deadline (Notice this week only 1 response to other student posting’s is needed). This response should evaluate the calculations made by the other student and confirm the solution or provide a suggestion on how to correct or improve the solution. Please evaluate a student that has not been evaluated before and do not post calculations for the other student! But you may suggest them. Let them do her/his own work. You may recommend them what this work is. 17.1.124.0/22 70 120 2

Explanation / Answer

Hi

FLSM:Originally , we were using fixed length subnetting divided into classes (class A, Class B ,Class C , Class D, Class E). Where Class A having larger scope , the subnet we use in this is /8, we can have 24 bit address range for host . In class B we can have 16 bit for host . While in Class C we can have 8 bit or /24 network as host.

Class D to be used for multicasting and Class E for research and scientific purposes.

VLSM:vairiable length subnet masking is quite similar to FLSM but it has flexibity to divide the subnet into further small subnets.

In FLSM : Class A ip address range from 1-127 in first octet.

network address: 1.0.0.0

Broadcast address:127.255.255.255

Host addresses comes in between.

similarly class B and class C address with mask /16 and /24 respectively.

Class B IP Addresses range from 128.0.x.x to 191.255.x.x. start with 128.0.0.1 end to 191.255.255.254.

Class C IP addresses range from 192.0.0.x to 255.255.255.x. The default subnet mask for Class C is 255.255.255.x.

VLSM: The need of VLSM was to save the unused IP address since the pool is getting exhausted very rapidaly in case of IPv4 address.Internet Service Providers may face a situation where they need to allocate IP subnets of different sizes as per the requirement of customer. One customer may ask Class C subnet of 3 IP addresses and another may ask for 10 IPs. For an ISP, it is not feasible to divide the IP addresses into fixed size subnets, rather he may want to subnet the subnets in such a way which results in minimum wastage of IP addresses.

For the rest , i could not connect with requirement. I would recommend if the complete question would be here since i am not refer privious thing.

Hope , the information provided will help you.

Thanks
