Please Whitelist This Site?
I know everyone hates ads. But please understand that I am providing premium content for free that takes hundreds of hours of time to research and write. I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. And I have a family to support, just like you. :)
If you like The TCP/IP Guide, please consider the download version. It's priced very economically and you can read all of it in a convenient format without ads.
If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. To do so, just open the Adblock menu and select "Disable on tcpipguide.com". Or go to the Tools menu and select "Adblock Plus Preferences...". Then click "Add Filter..." at the bottom, and add this string: "@@||tcpipguide.com^$document". Then just click OK.
Thanks for your understanding!

IP Addressing Concepts and Issues
Even though the original IP addressing
scheme was relatively simple, it has become complex over time as changes
have been made to it to allow it to deal with various addressing requirements.
The more advanced styles of IP addressing, such as subnetting
addressing, are the ones used most in
modern networks. However, they can be a bit confusing to understand.
To help make sense of them we must start at the beginning with a discussion
of the fundamentals of IP addressing.
In this section I begin our larger
exploration of IP addressing by explaining the key concepts and issues
behind it. I begin with an overview of IP addressing and discussion
of what it is all about in general terms. I describe the size of IP
addresses, the concept of its address space and the notation
usually used for IP addresses. I provide basic information on the structure
of an IP address and how it is divided into a network identifier and
host identifier. I then describe the different types of IP addresses
and the additional information such as a subnet mask and default gateway
that often accompanies an IP address on larger networks. I provide a
brief description of how multiple addresses are sometimes assigned to
single devices and why. I conclude with a description of the process
by which public IP addresses are registered and managed, and the organizations
that do this work for the global Internet.
Note: Remember that most operating systems have a calculator program that incorporates scientific functions, including conversions between binary, decimal and hexadecimal numbers.
