The Last Subnet How2 Doc v3.0
October 20th, 2009

Note that this was originally posted in May 2009
I wrote this document to help with my CCNA studies, the intent of the document was to help me quickly convert class A and B subnets for the test. The CCNA will present subnet questions in CIDR format and you should know how to answer them in less then 90 seconds.
I converted the document from Microsoft Word 2007 to PDF using doPDF6.3 a free PDF converter. So far it appears to have done a nice job. You can find it here >Do PDF
The document is here > The Last Subnet How2 Doc
Please let me know of any errors, spelling or grammar.
