There is a need for top level domain (TLD) names that can be used for

creating names which, without fear of conflicts with current or

future actual TLD names in the global DNS, can be used for private
|

testing of existing DNS related code, examples in documentation, DNS
|

For example, without guidance, a site might set up some local
|
| 177 |
additional unused top level domains for testing of its local DNS code
|
| 178 |
and configuration. Later, these TLDs might come into actual use on
|
| 179 |
the global Internet. As a result, local attempts to reference the
|
| 180 |
real data in these zones could be thwarted by the local test
|
| 181 |
versions. Or test or example code might be written that accesses a
|
| 182 |
TLD that is in use with the thought that the test code would only be
|
| 183 |
run in a restricted testbed net or the example never actually run.
|
| 184 |
Later, the test code could escape from the testbed or the example be
|
| 185 |
actually coded and run on the Internet. Depending on the nature of
|
| 186 |
the test or example, it might be best for it to be referencing a TLD
|
| 187 |
permanently reserved for such purposes.

Confusion and conflict can be caused by the use of a current or
|
| 357 |
future top level domain name in experimentation or testing, as an
|
| 358 |
example in documentation, to indicate invalid names, or as a synonym
|
| 359 |
for the loop back address. Test and experimental software can escape
|
| 360 |
and end up being run against the global operational DNS. Even
|
| 361 |
examples used $B!H(Bonly$B!I(B in documentation can end up being coded and
|

released or cause conflicts due to later real use and the possible

acquisition of intellectual property rights in such $B!H(Bexample$B!I(B names.
