Description:
------------
gethostbyname() is returning my own IP address for non-existent domain names. The expected behavior is that it will return the original name back to you.

Resolving a real domain returns it's correct IP address.

This issue affects other DNS resoluton commands too... for example, checkdnsrr('totallyfake456jh47r.com','A') returns TRUE.

Using local resolution commands, the expected result (NXDOMAIN) is returned:

/:~# host totallyfake456jh47r.com
Host totallyfake456jh47r.com not found: 3(NXDOMAIN)

This may similar (same?) as bug ID <a href='http://bugs.php.net/bug.php?id=21487&edit=2'>21487</a>.

PHP configuration: ./configure --with-apxs2=/www/bin/apxs --with-config-file-path=/etc --with-mcrypt --enable-ftp --with-gd=/usr/local --with-zlib-dir=/usr/local --with-jpeg-dir=/usr/local --with-png-dir=/usr/local --with-mysql --with-xml --enable-track-vars 

Reproduce code:
---------------
echo gethostbyname('totallyfake456jh47r.com');

Expected result:
----------------
totallyfake456jh47r.com

Actual result:
--------------
66.166.160.74

(my server's own IP)

It works fine here, when it fails to resolve the original 
domain string is returned. If you get anything else it 
could be due to named issues on your system.

Try removing this line:
domain YOUR_DOMAIN_NAMe
from /etc/resolve.conf file.
In my case this solved the problem.
