IP address and subnet mask

[josemavicente]

hello..say i put an ip addy like:


"192.168.0.4" ... can this be any number combination?

and i always see a subnet mask like

"255.255.255.250" ... can i edit the subnet mask? what is this for? http://www.PCGuide.com/ubb/redface.gif

Subnet are for bigger network, like you can divide all types of LANs into 3 subnets. Its basically for divided and naming each computer on a bigger LAN . The subnet you posting must be with the IP you posted. Its a numbering system and there are 3 different types of subnet e/g. 255.0.0.0
255.255.0.0 and 255.255.255.x

ok, thus if i am to network two computers together:

computer one says:
192.168.0.1
255.255.255.0

computer two says:
192.168.0.2
255.255.255.0

this will be ok right or am i doing something wrong?

Hello Jayvee,
The three different subnet mask ranges that Diurnal reffers to are called classes. Each group of numbers is a possible range of addresses. Some of these addresses are dedicated for specific things and are not available to use. I can't remember the exact number of available at the moment but I think it is 248. Therefore you would read 248X248X248 for a Class A.
Class A) 255-0-0-0, typicaly for huge networks, allows for in the range of 15 million addresses.
Class B) 255-255-0-0, for medium to large networks, allows for the range of 60,000 addresses
Class C) 255-255-255-0, for small networks, allows for the range of 248 addresses.
The groups of 255 are fixed numbers assigned to you, the 0 is a veriable that you can set for each machine. The subnet mask is simply a designation of the type of address you use.
Don't edit it http://www.PCGuide.com/ubb/wink.gif

ok so what youre trying to say is that the x.x.x.x for subnet mask refers to HOW LARGE a network you can have?

going back to my previous question, when you said that I should not edit the subnet mask, I was starting from scratch thus there's nothing specified yet. Thus, just to be able to CONNECT 2 COMPUTERS, what could the appropriate subnet mask be? im just connecting them directly (whats the term used for this type of connection again?) of course, meaning no HUB.

Hi Jayvee,
The subnet you want is 255-255-255-0.
The network definition is called a "Peer-to-Peer" and you would need to use a "Crossover" cable (no hub).
I am guessing you are using Windows 9X for OS. If so, just use the Network Wizard in you Help section. This will set up the first computer and allow you to make a disk to set up the other machine. The subnet mask and IP addressing will be done for you.
If you want to set this up yourself, the identification you have in your second post here will work.

Good luck http://www.PCGuide.com/ubb/cool.gif

thanks very much for the help.

one last thing:

i will need to add certain protocols right? these would be tcp-ip and ipx, along with file and print sharing.

follow up question: how do you connect printer to network? i have the software installed on both computers and i wanna be able to print using both. (e.g. Computer1 has printer. I wana print from Computer2)

thanks very much for the help from all of you.

To use the printer on both you need to allow "Print Sharing". Right click "Network Neighborhood" \ click Properties \ click the File and Print Sharing button. Make sure the box is checked.
