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!
Sincerely, Charles Kozierok

The success of the global Internet
relies on the development of universally-accepted standards for protocols
and other technologies. Internet
standards organizations such as the IETF
are thus critically important; they manage the standards development
process, to ensure that everyone agrees on how to create hardware and
software that will work together to communicate world-wide.
Important Standardization Functions
While the need to standardize protocols
seems obvious, there are a couple of other aspects to Internet standardization
that are equally important but perhaps not quite as well understood:
- Parameter Standardization: Most protocols
rely on the use of parameters that control how they function. As just
two of many, many examples, the Internet
Protocol has a set of numbers that define
different IP options, and the Address
Resolution Protocol (ARP) has an Operation
Code field that can take on many different values. Just as it is
essential for devices to agree on what protocols to use, they must also
agree on what parameters to use for those protocols, if communication
is to be successful.
- Global Resource Allocation and Identifier
Uniqueness: There are a number of resources that are used on the
Internet that must be allocated from a fixed set of values and where
uniqueness in assignment is essential. The most obvious example is that
each TCP/IP host must have a unique IP address;
another important example is ensuring that only one organization uses
a given DNS
domain name. If two devices have the same
IP address or two organizations try to use the same domain name, the
results would be unpredictable, but almost certainly bad.
