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!

TCP/IP Network Status Utility (netstat)
(Page 1 of 6)
TCP/IP is a very complex protocol
suite, as I am sure you would agree after perusing the contents of this
Guide. It is actually quite amazing that most of the time, all of the
different protocols, services and programs perform their jobs both efficiently
and silently. Most of us dont even realize just how much is going
on in the background, and thats as it should be. J
On the other hand, when a problem does occur on a TCP/IP network, the
administrator charged with fixing it needs to obtain as much information
as possible about what all those bits and pieces of the suite are doing
behind the scenes. The network status utility, netstat, is provided
for this purpose.
The netstat program is very
simple in concept, being designed for only one purpose: to show information
about the operation of TCP/IP on a device. The aforementioned complexity
of TCP/IP, however, leads to netstat being rather elaborate itself:
the program can provide a large variety of information. As usual, the
options and output of netstat depend on the particular operating
system type and version. It is somewhat different on UNIX and Windows
machines, so I will describe each platform separately.
