How can I get information about a domain name (such as owner or server details) using PHP or Python code? I'd like to avoid using any 3rd party web site.
Is this possible?
-
Are just excluding 3rd party webtools? whois db, DNS are by definition third party services. And fingerprinting serverdetails is a hard problem to tackle on your own without use of third party libraries.Chris Wesseling– Chris Wesseling2014-03-21 09:18:26 +00:00Commented Mar 21, 2014 at 9:18

You can base yourself on the following whois script: http://www.phpeasycode.com/whois/
The script first checks for the right whois server and then opens a socket on port 43. Here's a simpliefied query function based on the code from the demo above.
Each TLD has its own whois server. You can find a complete list here : http://www.iana.org/domains/root/db/ and http://www.whois365.com/en/listtld/
<?php
$whoisserver = "whois.pir.org";
$domain = "example.org";
$port = 43;
$timeout = 10;
$fp = @fsockopen($whoisserver, $port, $errno, $errstr, $timeout) or die("Socket Error " . $errno . " - " . $errstr);
fputs($fp, $domain . "\r\n");
$out = "";
while(!feof($fp)){
$out .= fgets($fp);
}
fclose($fp);
$res = "";
if((strpos(strtolower($out), "error") === FALSE) && (strpos(strtolower($out), "not allocated") === FALSE)) {
$rows = explode("\n", $out);
foreach($rows as $row) {
$row = trim($row);
if(($row != '') && ($row{0} != '#') && ($row{0} != '%')) {
$res .= $row."\n";
}
}
}
print $res;

Just a link?... You missed a chance of making a real answer. The OP is from url to domain & server details. With little effort you can show how PHP shines in parsing the hostname from the url and make a start investigating server details.

Thanks, I didn't want to link directly to the download to give credit to the author.

I'm sorry, I'm warming up today. I'll edit the question to include some information as how the script works.

Answering questions is nice. Links are great. Giving credit where credit is due, even better. I'm not saying you should write a book or whole script in the answer. But the web is already full of forums with short First Post links that have rotted. With little extra effort you'll have something that survives the tests of time somewhat longer.

First make your live easier:
pip install python-whois
pip install requests
Then do something like:
>>> import requests
>>> import urlparse
>>> import whois
>>> url = 'http://docs.python.org/3/'
>>> requests.head(url).headers['server']
'Apache/2.2.22 (Debian)'
>>> hostname = urlparse.urlparse(url).netloc
>>> print whois.whois(hostname)

actually, the previus answer now is wrong, urlparse change to urllib.parse, so it will be :
import requests
import urllib.parse
import whois
url = 'http://docs.python.org/3/'
requests.head(url).headers['server']
'Apache/2.2.22 (Debian)'
hostname = urllib.parse.urlparse(url).netloc
print (whois.whois(hostname))
