YO;
May I direct you to a book that may answer your question? it's "The complete pc upgrade and maintenance guide by Mark Minasi 11th edition. If you find it in a library turn to chapter 27 pg 1106-1109. also check out this website: www.techtv.com and check the pages for callforhelp,cybercrime and the screensavers. I hope this info will help.

good luck.

What you need is an TCP/IP book to help you out with subnetting? I recommend TCP/IP Unix Administrator by the publisher O'Reilly. This will help you out alot and if you need further info please feel free to contact me at donna_duffie@yahoo.com.Donna

Subnet masks are a fundamental component of IP networking and routing. Briefly, a subnet mask defines how large an address space your network may occupy--how many computers you can connect if you will.

An understanding of how subnet masks work requires an understanding of the structure of an IP address. Cisco has some wonderful links in the public sections of their web site. Two in particular that I would recommend to you are the Technical Tip "IP Addressing and Subnetting for New Users" and Cisco's IP Subnet Calculator, which will help you grasp the relationship between subnet mask and subnet size.

Cordially,

http://www.learntosubnet.com was the most helpful tool when I was studying for the MS TCP/IP exam. You don't need to read a whole book to grasp the concepts of custom subnetting. This site has some practice examples (about 9 of them) including answers
which after reading the information on this site will greatly improve your understanding. It has been a year since I studied it, but I developed a way to use the Calculator (in Scientific Mode) to detemine my custom subnets. Put in how manyaddresses you need, convert to Binary and count how many of the 32 bits are required to meet the desired results, and vise versa. Read all the information on this site. It will click and then you will then
be successful. geo1.

Check out this site for an excellent TCP/IP Tutorial.

One trick to remember when identifying which subnet a particular address belongs to is instead of converting the octet to binary for "anding" the mask, use the windowscalculator in scientific mode and the "and" key. Saves a lot of time, just get the concept down first.
