TOPIC: My networking assignment

Re: My networking assignment 10 years 6 months ago #29673

rite here is my subnets then, hopefully :-p

Server 1 = 255.255.255.252
Server 2 = 255.255.255.252
Admin (48 PCs) = 255.255.255.192
Sales (48 PCs) = 255.255.255.192
Warehouse (62 PCs) = 255.255.255.192

Rite as for IP's I was lost on if I need to work them out and decode to binary?

Server 1 = 10.1.1.254
Server 2 = 10.1.1.253
Admin (48 PCs) = 10.1.1.252
Sales (48 PCs) = 10.1.1.251
Warehouse (62 PCs) = 10.1.1.250

Correct :), except for the two servers. There has to be an IP for the router interface connected to the small switch, so 255.255.255.252 is not enough. You need 255.255.255.248 or above.

Server 1 = 10.1.1.254
Server 2 = 10.1.1.253
Admin (48 PCs) = 10.1.1.252
Sales (48 PCs) = 10.1.1.251
Warehouse (62 PCs) = 10.1.1.250


No, if you convert the Admin,Sales and Warehouse above to binary you will see that the network bits are the same. Which is not correct. Unfortunately, "Binary" is a must if you want to learn sub-netting. There just no way out of it.

Instead of reinventing the one wheel that has been reinvented over and over. I'd refer you to some guys who can probably teach you sub-netting much better than I do.





I'd recommend watching the whole series, and if after that you're still in trouble, we have other links that might help.

after going through your subneting course make sure you memorise this, it will make you subnet at light speed, and understand vslm much better

/26
What do we know about a /26?
192 mask
2 bits on and 6 bits off (11000000)
Block size of 64
4subnets, each with 62 hosts

/27
What do we know about a /27?
224 mask
3 bits on and 5 bits off (11100000)
Block size of 32
8 subnets, each with 30 hosts

/28
What do we know about a /28?
240 mask
4 bits on and 4 bits off
Block size of 16
16 subnets, each with 14 hosts

/29
What do we know about a /29?
248 mask
5 bits on and 3 bits off
Block size of 8
32 subnets, each with 6 hosts

/30
What do we know about a /30?
252 mask
6 bits on and 2 bits off
Block size of 4
64 subnets, each with 2 hosts

block size = 256-mask

Regardless whether you have a Class A, Class B, or Class C address, the /30 mask will only
provide you with two hosts, ever. This mask is suited almost exclusively—as well as suggested
by Cisco—for use on point-to-point links.

ok then thanks, so I could use 255.255.255.248 for both servers then?

Server 1 = 10.1.1.254
Server 2 = 10.1.1.253
Admin (48 PCs) = 10.1.1.252
Sales (48 PCs) = 10.1.1.251
Warehouse (62 PCs) = 10.1.1.250

And thanks Sose for your reply also, will be checking that out in more detail too once I have gotten this subneting fully cracked.
