Hi,

Assuming that you would want each floor to be on its own subnet, and that a total of 86 employees are distributed more or less equally among the floors (28-29 per floor), and your starting Class-B network address is 172.31.0.0

3 subnets (one per floor) required with atleast 29 hosts per subnet.

We can go with the 255.255.255.224 mask to give 30 useable hosts per subnet.

The subnets would be:

Sub Network 1: 172.31.0.0
Host Range : 172.31.0.1 - 172.31.0.30
Broadcast Address: 172.31.0.31


Sub Network 2: 172.31.0.32
Host Range : 172.31.0.33 - 172.31.0.62
Broadcast Address: 172.31.0.63


Sub Network 3: 172.31.0.64
Host Range : 172.31.0.65 - 172.31.0.94
Broadcast Address: 172.31.0.95

Hope this helps.

Regards.

Subnet mask for 86 PCs is more than 64 and less than 128. it means that subnet mask is 255.255.255.128
You can have PC IP address in range 172.31.0.129 - 172.31.0.254

So many young unemployed school leavers and so many children who cannot read or read with understanding, maybe they could get together?

Bringing together young unemployed school leavers and children who struggle with reading or comprehension can be a beneficial initiative with potential positive outcomes. Such collaboration could create a mutually beneficial learning environment and address the challenges faced by both groups. Here are a few ideas on how they could come together:
  1. Mentorship Programs: Establish mentorship programs where unemployed school leavers serve as mentors to children who struggle with reading. The mentors can provide guidance, support, and assistance in developing reading skills while also imparting life skills and sharing their own experiences.
  2. Tutoring Programs: Organize tutoring programs where unemployed school leavers can offer one-on-one or small group tutoring sessions to children in need of reading support. This can be done in schools, community centers, or through local organizations dedicated to education or literacy.
  3. Reading Clubs or Book Circles: Create reading clubs or book circles that bring together young unemployed individuals and children. The groups can meet regularly to read and discuss books, fostering a love for reading and improving comprehension skills.
  4. Volunteer Opportunities: Connect unemployed school leavers with volunteer opportunities in libraries, literacy organizations, or after-school programs focused on reading. They can assist in organizing reading events, facilitating reading activities, or helping children with reading assignments.
  5. Community Projects: Encourage collaborations on community projects that promote literacy. This could involve organizing book drives, establishing community libraries, or conducting literacy awareness campaigns to raise awareness about the importance of reading.
  6. Collaborative Learning Spaces: Create safe and inclusive spaces where young unemployed individuals and children can interact and learn from each other. These spaces can provide resources like books, educational materials, and technology to support reading and learning activities.
  7. Partnerships with Schools and Organizations: Foster partnerships between schools, youth organizations, and literacy-focused organizations to implement joint initiatives that address the needs of both groups. This can involve coordinated efforts to provide educational support and resources to children while offering employment and skill-building opportunities to unemployed school leavers.

How to figure out your default subnet mask

A subnet mask is a 32-bit binary number, very similar to an IP address. And like an IP address, the subnet mask is usually expressed as a set of four octets written in decimal form, with each octet separated by a period.

The subnet mask is used by routers and switches to determine which part of a computer or other device's IP address is the network identifier, and which part is the host identifier. There are three default subnet masks, one for each of the IP classes A, B, or C. The default subnet masks are:

Class A = 255.0.0.0
Class B = 255.255.0.0
Class C = 255.255.255.0

To determine the default subnet mask for your network, all you need to do is see which class your network falls into. A network's class is assigned based on the first octet (the set of digits before the first period) of the IP address. For example, to find out which class the network 123.22.8.0 belongs to, you would see where "123" fits into the following table:

First Octet: Class:
1-126 = Class A
128-191 = Class B
192-223 = Class C

So for the example above, 123.22.8.0 is a Class A network, which means it would have a default subnet mask of 255.0.0.0.

Most home and office networks will be Class C networks, so your default subnet mask will typically be (you guessed it) 255.255.255.0. Not all networks use the default subnets, but for those that do, figuring it out is easy once you know which class your network fits into.

Subnet mask

subnet mask is usually 255.255.255.000, or something like that. If you not know what it is, no use trying to set it up. Most devices do set this up after they know what the ip address is. Look what the router or your hub makes for other devices. The gateway (address) is the ip address your provider gave you to connect to.

How do i establish a subnet with a A address

The subnet is determined by the subnet mask. Class A addresses are contained in the following range: 0.0.0.0 - 127.255.255.255. The most common use of a class A address is 10.0.0.0

In class A networking you may use a subnet mask from 255.0.0.0 all the way to 255.255.255.255

The subnet would work as the following example:

Network Address: 10.x.x.x
Subnet mask: 255.0.0.0

The first number in the above example would determine our subnet. So if you have 2 devices and you would want to put them in a different subnets you would want the first octet (octet is each number seperated by periods) to be a different number.

Network 1: 10.x.x.x
Network 2: 11.x.x.x

Unless these devices use a router to communicate they would not "talk" properly. Thus giving you 2 different subnets.

I am setting up a D-Link AirPlus DWL-800AP+. I can use it as an access point or repeater, I need the repeater. I access the internet through a wireless signal that serves one floor of my building. I can...

You must be on the same subnet of the AP. Static your IP address to 192.168.0.29 with a subnet of 255.255.255.0. If it's hooked up to the same network you are, you should get in.

Adding additional computer problem

Yes, the xp machine connects to the net. DHCP is not enabled. The ipconfig/all command brings up the correct static ip address, subnet mask, and default gateway. But it does also say under the ip configuration that ip routing is not enabled. I did have the 2000 machine connected when I first set up the router yesterday, but I booted up my laptop to try to set up a wireless connection, and then I had to reinstall the entire router set-up.

Putting right the ip address ?

Before you proceed you need to know the static IP, Subnet Mask and Gateway address for this printer. Once you have them: -Enter the menu mode by pressing the + button -Press the + button till you come to the Network Menu. -Press the Enter button. You should now see TCP/IP. Make sure it says Enabled which is the default setting. -Press the + button till you come to IP address then press the Enter button. - IP addresses (for now) consist of four octets or four groupings of three numbers such as in this example *192.168.001.123*. Using the + or - buttons (+ counts up 0,1,2,3?.; - counts down 255,254,253?..) you are going to set the number of the first octet or in the case of the example *192*. Once you?ve set it correctly hit the Enter button. -Do the same for the other three octets. Hitting the Enter button after setting the fourth octet will set the new IP and take you back to the TCP/IP menu. - Press the + button till you see Subnet Mask and press the enter button. - Just like the IP address the Subnet Mast consists of four octets. Set the value to you needs just as you did with the IP address. Again when you hit the enter button after setting the fourth octet you will be taken back to the TCP/IP menu. - Again press the + button till you come to Gateway Address and hit enter. Enter the Gateway IP address exactly like you did when setting the IP address. Don?t forget to hit the enter button to set the address. You should now be at the TCP/IP menu again. -To exit the menu press the On-line button on the printer. Your printer should now be configured with you IP address, subnet mask and gateway address. As an added check I would go back into the menu by pressing the + button, going into the Information Menu and printing selecting the Print Menu Map option. Verify the setting we just made with what is printed out at the top of the page. If everything matches you?re ready to go! Let us know how it goes and please don?t forget to rate this posting.
