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

DNS Root Name Servers
(Page 3 of 3)
Current Root Name Servers
Originally, the root name servers
were given domain names reflecting the organizations that ran them.
In these historical names we can see a veritable who's who
of the big players in the development of the Internet: ISI, NASA, the
United States military and others. Several of the servers are still
run by government agencies or the US military, where added security
can be put into place to protect them. For convenience, however, all
the root name servers are now given alphabetical letter names
in the special domain root-servers.net.
Table 167
shows the most current information about the DNS root name servers as
of the date of publishing of this Guide. For your interest and amusement
I have also mapped the locations of these servers in Figure 242.
