hostname is diplaying IP address

[tommy916]

I didn't know that 1.6 has new hostname added.
but the hostname displays the ip address. I don't know if this only happen for Win server.
I looked in mysql database and see the IP address instead of hostname in Hostname table.




<?php echo $REMOTE_HOST; ?>
<?php echo $HTTP_SERVER_VARS["REMOTE_HOST"]; ?>
<?php echo $_SERVER["REMOTE_HOST"]; ?>

I tried all above but it shows IP addresss.

That is a apache or IIS problem. You need to fix the setting within your web server.

Problem solved... from
http://www.php.net/manual/en/function.gethostbyaddr.php


$hostname = @gethostbyaddr($_SERVER['REMOTE_ADDR']);

That will work too. :D

I am still with the same problem...
Using :
$REMOTE_HOST; or
$HTTP_SERVER_VARS [REMOTE_HOST "]; or
$_SERVER [REMOTE_HOST "];

I received the message of Unavailable

Using the function:

gethostbyaddr($_SERVER['REMOTE_ADDR']);

now I get to receive IP. How to solve?

Most likely you need to turn on hostname look ups in IIS or apache, whichever you are using.

I recommend that you do not use it. I decided to disable it. Most hosting disable it too. Because the reverse DNS lookup will slow down your website serioiusly. It did slow down my server 20 times than normal while it was trying to find the hostname for that IP address. You can look for more info about reverse dns lookup in search engine.

you can use other site for dns lookup like http://arin.net/ http://remote.12dt.com/rns/
