- File and other Requirements
- ===========================
-
- Files YOU require that are NOT included in this distribution:
-
- VBRUN300.DLL
-
- The following files should be included:
-

-
-
- =================
- Installing SUBNET
- =================
-
- 1) Unpack using PKUNZIP the SUBNET10.ZIP file in a temporary location
- (ie: C:\TEMP). The following files should be included:
-
- SUBNET10.ex_ Program
- README.TXT Description
- LICENSE.TXT Registration information
- setup.exe Setup program used to install FTP_GM
- setup.lst Used by setup.exe
- setup1.ex_ Used by setup.exe
- setupkit.dl_ Used by setup.exe
-
-
- 2) Run SETUP.EXE
-
- Setup will create a new group under Program Manager and will create
- and setup the SUBNET icon.
-
- 3) Run SUBNET.EXE by clicking the icon SUBNET, or by selecting 'RUN'
- from the 'File' menu option under Program Manager.
-

- =====================
- Description of SUBNET
- =====================
-
- SUBNET is a tool for any network individuals involved in assigning
- TCP/IP addresses for networks.
-
- SUBNET can be used to:
-
- ò Determine a proper subnet mask (ie.: 255.255.255.192
- vs. 255.255.255.224)
- ò Calculate number of subnets and hosts per subnet when a
- number of bits to use for subnetting has been
- specified
- ò Manage IP address assignements
-
- ò Use VLSM (Variable Length Subnet Mask) to conserve addresses
-
- ò Generate ATM NSAP (AESA) addresses
-
-
-
- ==================
- How to use SUBNET:
- ==================
-
- 1- Run SUBNET as per the instructions above
- 2- Enter you TCP/IP address in the four fields provided, in the
- traditional dot.decimal notation:
-
- xxx.xxx.xxx.xxx
-
- Each field represents one of the 4-byte address components. Each
- field range is 0-255.
-
- 3- While entering the first byte component, the standard subnet mask for
- the IP address network class is automatically setup. Example:
-
- Enter 135
-
- The subnet mask becomes 255.255.0.0 for a class B address
-
-
- Enter 194
-
- The subnet mask becomes 255.255.255.0 for a class C address
-
-
- 4- Click on the LOGICAL AND button.
-
- This action causes SUBNET to logically AND in binary format the
- decimal entries you put in. SUBNET converts the decimal notation to
- binary automatically, and calculates the number of bits which remain
- for assigning IP addresses to hosts.
-
- Note:
- To see the actual binary display, maximize the screen. The display
- is to the right-most side of the screen. This will only work on
- display drivers capable of larger than 640 x 280 display.
-
- You are now ready to use available bits for subnetting your network.
-
- The following 3 new data is given to you:
-
- Info Description
- -------------------- -----------------------------------------
- Network: xxx.xxx.0.0 xxx always the primary network
-
- Host bits remaining Number of bits available for hosts
-
- No. of bits can be
- used for subnetting Usually the number of hosts bits remaining
- less 2 (always need at least 2 bits for
- hosts).

-
- Knowing how many bits to use for subnetting
- -------------------------------------------
-
- SUGGEST MASK
-
- If do not already know how many bits you should be using for subnetting,
- then click on the SUGGEST MASK button. A new window titled 'Subnet
- Mask - Suggestion' appears. Click on the SUGGEST button.
-
- You will be ask the following 2 questions:
-
- ò How many hosts per segment/subnet (the largest one)?
-
- For each and all subnets, there will be hosts (hosts, bridges,
- routers). One or more of these subnets will have the highest
- amount of hosts/bridges/routers.
-
- To ensure you have enough bits left after subnetting, for
- addressing all these hosts, you must enter that value to this
- field. The default entry is 2.
-
- ò How many subnets do you need to support (2-??)?
-
- You have to know how many networks you will have. Keep in mind
- that if you are adding routers and/or wide area networks, that
- in most cases you will be assigning seperate network (subnets)
- to each WAN. Example:
-
- Corp-Net --Router--| Wide Area Network |--Router--Remote_Office
-
- The above network would require at least 3 subnets;
-
- 1 for Corp-Net
- 1 for Wide Area Network
- 1 for Remote_Office network
-
- The default entry is 14.
-
- Once you have answered the 2 questions, a suggestion will be displayed
- as to what the mask should look like. Example:
-
- I have class C address; I need 30 subnets with 4 hosts on each.
-
- SUBNET would suggest 255.255.255.248
-
- SUBNET also points out how many bits of subnetting you will need to use
- as a result of this mask and this requirement. In the above example,
- SUBNET will add the following message:
-
- 'Note: To achieve these subnets and hosts numbers, use 5 bits
- for subnetting.'
-
- Had there been other options for a mask, SUBNET would add the next
- likely candidate and will tell you about the alternative mask and
- required number of bits for subnetting.
-
- SUBNET's Suggest algorythm suggests both the Mask and resulting number
- of bits of subnetting.
-
- Click on DONE if the suggestion is acceptable. Now on your main Subnet
- window, you will see the 'suggested' mask placed there for you. To
- see the new amount of host bits and still remaining number of bits for
- subnetting, press the LOGICAL AND button once more.
-
- NOTE: If you plan to use 'Calculate Subnets & Hosts', return the mask
- to what it was first, ie.: 255.255.0.0 or 255.255.255.0, etc. If you
- do not, SUBNET will tell you to do so anyway. Then click on LOGICAL
- AND.
-
-
- CALCULATE SUBNETS & HOSTS
- -------------------------
-
- 1. If you used 'SUGGEST MASK', put the mask back to what it was, ie.:
- 255.255.0.0 or 255.255.255.0, etc., then click on LOGICAL AND.
-
- 2. Enter number of bits to use for subnetting. This number must not
- exceed the displayed 'No. of bits can be used for subnetting' value.
-
- 3. Click on CALCULATE SUBNETS & HOSTS. If you started with a class C
- address, it should be fairly quick. If you started with a class B or
- class A address, SUBNET will warn you that you might have to be
- patient. As long as the hour-glass is displayed, it is working.
-
- 3. Once the mouse pointer returns to normal (hour-glass to pointer),
- then click on View. A new screen will appear showing on its top
- window bar, your IP network address and resulting subnet mask, ie.:
-
- 194.5.6.0 - 255.255.255.224
-
- The screen also has 5 iconized screens with the following titles:
-
- - Subnets (Decimal)
- - Broadcasts (Decimal)
- - Hosts Range
- - Subnets (Binary)
- - Broadcasts (Binary)
-
- You can view any/all.
-
- 4. Click on File/Exit to close the viewer and restart your calculations
- if needed/wanted.
-
-
-
- =================
- SAVING & PRINTING
- =================
-
- To save data to disk, initiate your calculations as described above, then
- view the results as described above. Click on the Hosts Range icon
- (if the list is not already displayed). The SAVE button is enabled on
- ONLY this screen.
-
- Depending on the package/bundle of SUBNET you have, the following are
- the options available:
