Here is Binary (base two) along with
some information on Hexadecimal (base 16), Octal (base 8) and
our good friend, decimal (base ten).
 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.
 PowerPoint Slides: IP addressing,
subnet masks and IP numbers.

masks for OLDER BROWSERS and CEEE lab.

Subnet Masks and IP numbers.
 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.

email explanation of the
two IP and subnet masking illustrations.
 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.
