IP addresses and subnet masks

  1. Here is Binary (base two) along with some information on Hexadecimal (base 16), Octal (base 8) and our good friend, decimal (base ten).

  2. Class #1 (Monday, January 9th, 2007) handouts are one on binary subnet mask values and another on binary basics and IP numbers and subnetting, with class A, class B, and class C information. We'll cover this in classes 4 and 5 after the Martin Luther King holiday weekend, probably going into week #3 too.

  3. PowerPoint Slides: IP addressing, subnet masks and IP numbers.

    Slides: Chapter 11 IP, subnet masks for OLDER BROWSERS and CEEE lab.

  4. Subnet Masks and IP numbers.

  5. Subnets, IP numbers, NIC addresses: Base two and base ten and binary. Multiplying by 10 or 100 or 1000 or 10,000is soooooooooo easy, whether in decimal OR in binary! Multiply by 2 or 4 or 8 or 16 is a cinch in binary.

  6. Click to see Subnet Mask concepts illustrated using Excel and Photoshop.

  7. Legal Subnet mask values for x, or y or z depending on class A or B or C. Recall that w.x.y.z is the way we refer to IP numbers in dotted decimal notation. Each letter w or x or y or z represents on octet of 8 bits.

The Spring 1999 web page, the Spring 2000 page, Spring 2001 810:023 page, Spring 2002 810:023 page, Spring 2003 810:023 web page, Spring 2004 810:023 web page, Spring 2005 810:023 web page, Spring 2006 810:023 and finally the Spring 2007 810:023 Microcomputer Systems web page all are useful to see what kinds of topics are covered in this class. Keep in mind, the rate of change for networks, PCs and operating systems means the class will change quite a bit in response.
