Curl Ip Address

How to specify the IP address on curl?

You should be able to use

curl --interface zz.zz.zz.zz http://example.com/

How can I see which IP was used by me on curl?

I'm pretty sure this is not possible, i.e. not in a generic way.

The only way is to have the website report the source IP it sees and send it back as a header / part of the payload, etc. (Basically what the websites suggested in the other answer do)

How to execute the same curl request on a sequence of server IPs (URLs)

You can either use shell's brace expansion in bash, e.g. {2..15} for 2,3,4,...,15:

curl ... http://x.x.x.{2..15}:8080/services/test

or, curl's alphanumeric series [] operator in the URL part (notice the double-quotes):

curl ... "http://x.x.x.[2-15]:8080/services/test"

Alternatively, you can use arithmetic for loop:

for ((i=2; i<=15; i++)); do
    curl ... "http://x.x.x.$i:8080/services/test"
done

How can I make a CURL request to IP Address PHP?

Try with:

curl_setopt($ch, CURLOPT_URL,"http://127.0.0.1/script.php");

and CURLOPT_POSTFIELDS sould be an array:

$data = array('postdata' => 'postdata', 'postdata1' => 'postdata1');
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

curl always connects to a specific ip:port pair

To be sure what is happening, turn on verbosity with -v switch:

$ http_proxy=1.2.3.4:8080 curl -v http://google.com
* About to connect() to proxy 1.2.3.4 port 8080 (#0)
*   Trying 1.2.3.4...
* Connection timed out
* couldn't connect to host
* Closing connection #0
curl: (7) couldn't connect to host

In your case, I'd guess that Curl tries to use proxy. If that is the case, you should check the following:

• http_proxy environment variable:

Check:

env | grep -i proxy

• Curl configuration file ~/.curlrc (unlikely, it doesn't show in strace)

• Proxy can be proxided on command line (-x or --proxy), so check if curl isn't aliased in your shell

PHP Curl Not connecting to a url with IP Address and PORT

Using the redacted ip and a slightly modified version of your code as follows:

$url='http://X.XXX.XX.XX:8000/payments/accounts/v1';
$curl = curl_init();
curl_setopt_array($curl, array(
        CURLOPT_URL => $url,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_ENCODING => '',
        CURLOPT_MAXREDIRS => 10,
        CURLOPT_TIMEOUT => 1000,
        CURLOPT_CONNECTTIMEOUT => 1000,
        CURLOPT_FOLLOWLOCATION => true,
        CURLOPT_POST=>true
    )
);
$res=curl_exec( $curl );
curl_close( $curl );

printf('<pre>%s</pre>',print_r( $res, true ));

Yields:

{"detail":"Authentication credentials were not provided."}

Perhaps if you were to actually include and submit some post data in the CURLOPT_POSTFIELDS option you might find a different response.

Get only the IP Adress in Anaconda Powershell

In Windows PowerShell, curl does not refer to the external curl.exe program; instead, it is a built-in alias for PowerShell's Invoke-WebRequest cmdlet.

In order to invoke curl.exe, include the filename extension, .exe:

curl.exe ipinfo.io/ip  # Note: The https:// part isn't strictly needed.

Note that this is no longer necessary in PowerShell (Core) v6+, where the curl alias has been removed, along with others, so as not to shadow external programs that come with the operating system.

---

Also note that you could also have used the Invoke-RestMethod cmdlet, which - unlike Invoke-WebRequest, which returns a wrapper object around the actual data - returns the response data directly (and, as applicable, parses XML data into [xml] instances and JSON data into [pscustomobject] instances); its built-in alias is irm:

irm ipinfo.io/ip  # irm == Invoke-RestMethod

---

As a general tip: To determine which command (a PowerShell-native one or an external program) a given name such as curl refers to, use the Get-Command cmdlet.

• By default, the effective command by that name will be listed.
• If you add the -All switch, you'll potentially see shadowed command forms.
  

  • On Windows, if an external program is shadowed, you can still invoke it by excluding the .exe extension, as shown.

  • Generally, if a shadowed command is of a different type than the effective command, you can use the Get-Command's -Type parameter to target the shadowed command and invoke it via &, the call operator; e.g., the (less desirable) alternative to appending .exe on Windows would be:

    & (Get-Command -Type Application curl) ipinfo.io/ip
