Previous Comments: ------------------------------------------------------------------------ [2003-01-07 09:48:43] pollita@php.net It's possible that your DNS is setup with a search domain that has a wildcard. I'd like you to try two things: 1) gethostbyname("gms.de5."); <--- does that return an IP address as well? (Note the trailing dot) 2) Check your TCP/IP Properties | Advanced Settings | DNS Tab | describe every single piece of information on this property sheet, give detail. Interrestingly there doesn't seem to be a revese lookup for 62.75.134.200... ------------------------------------------------------------------------ [2003-01-07 06:56:17] nicos@php.net With the following script: <?php $db = gethostbyname("gmx.de5"); var_dump($db); $db = gethostbyname("gmx.de"); var_dump($db); ?> Edin can't reproduce the problem under windows. Can you please try that script? You're saying that host gmx.de5 on the server reports an error but you're under windows and windows doesn't have 'host'... Are you sure your DNS is working fine? I'm getting 213.165.65.100 from gmx.de and not 62.75.134.200... gethostbyname() is also supposed to return the hostname on failure. At least thats what we (Edin and me) are getting under Windows and Linux/Unix. Thank you for your report. ------------------------------------------------------------------------ [2003-01-07 06:51:57] nicos@php.net Just a note, I can not reproduce the problem under Linux/Unix. ------------------------------------------------------------------------ [2003-01-07 06:32:02] corinl@gmx.de Hi, try this: echo(gethostbyname("gmx.de5")) output is: 62.75.134.200 in fact, this domain doesn't exist, only gmx.de exists. ('host gmx.de5' on the server reports an error) this behavior is bad when for example using getbyhostname to validate an email address, because an email send to someone@gmx.de5 would surely not arrive... ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=21487&edit=1
