Description:
------------
There are domains that checkdnsrr is reporting that they do not exist, while when I search the domain names in several respectable domain registration websites they indicate that the domain names exist. An example is netvoice.com and ataz.com

Reproduce code:
---------------
  if (checkdnsrr("netvoice.com", "ANY")) echo "domain name has been taken";
   else echo "domain name is available";

Expected result:
----------------
I expect the code to tell me the domain name has been taken

Actual result:
--------------
The result is the domain name is available

The most likely cause for this is that your resolv settings are configured to include a search domain for which a wilcard exists.  Try appending a . to the end of hostnames which you wish to check to prevent the search name from being appended.

i.e.

if (checkdnsrr("netvoice.com.", "ANY")) echo "domain name has been taken";
   else echo "domain name is available";

I have appended a dot at the end of the domain name but still getting the same result.

What does `host netvoice.com` or `nslookup netvoice.com` return for you ?
