whatismyip | Simple PHP Script to return your true external ip | TCP library

I need to get my public IP address through C/C++ calls. I know as an alternative I can get from external links like "http://whatismyip.akamai.com"

I wrote a sample to get external IP address. But my program is not returning external IP address. I am getting internal IP address. Am I missing anything here?

If it is not possible through this way, Can I read DNS and get IP address? OR is there any way I can get external IP address programmatically using C API (Not by reaching some website )?

I tried making a simple chat system in Delphi 10.3.3 Community Edition using FireMonkey and the Indy components TIdTCPClient and TIdTCPServer.

It works fine if the Client and Server are located in the same WiFi network (Server = Windows 10 and Client = Android 10). I used the computer's IPv4 address shown in ipconfig to get the computer's IP, and my mobile phone successfully connects.

But, if I use the internet IP (got it from https://www.whatismyip.com/de/), the client shows the german equivalent to "socket error # 111 connection refused", so what am I missing? I entered the IP in the edit box to connect to - so if the local IP works, why doesn't any other IP work as well?

Here is the code I used:

GOAL : I am trying to deploy my Flask app to make it public on the web. I have my own server which runs on Ubuntu 18.04

TUTORIAL : As it is the first time I am doing this, I am following this tutorial. All his steps are perfectly working for me except the last one. However, in this tutorial he used Linode and I use my own server so I directly code on my terminal

PROBLEM : In his last step after systemctl reload apache2 when I go on the my browser and type my ip address (found using ifconfig) that I put in webApp.conf (192.168.1.25) I get the following error :

ERROR LOGS : As asked I went into the error.log which outputs the following : You can find the code here : https://pastebin.com/g2rzRUXE

POTENTIAL PROBLEMS: From what I understand I am having two issues :

1. Set the 'ServerName' directive globally to suppress this message . So I tried to solve it using this tutorial and I changed my private ip address to my public ip address (found on whatismyip.com) but when doing so I received the following error:

   1. It does not seem to like my prints: . Am I not allowed to keep prints

Please let me know how I could solve these problems or the other ones in the error log that I might not have seen.

I hope I was clear enough. If you need any additional info I can edit my question. I am running out of ideas so if you have any tips I would be grateful.

I have noticed that the user location reported via Application Insight is very unreliable. It is reporting my location in different state, Whereas when using WhatisMyIP it is able to accurately report my location.

Why such a difference with Application Insight ?

Here is what Appliction Insight Reports:

Here is the accurate location reported by WhatIsMyIP

I am expecting browser to show Proxy value, but it reveals my actual IP. Any idea why ?

I need to write a shell script for the purpose of unblocking the current ip from a server. The script must run on mac os.

The script is finished i just need to get the right ip adress, the one i connect to the internet with. If a hit 'ipconfig getifaddr en0' in the console i get the following adress: 127.168.X.XXX. But when I use a service like 'whatismyip.com' im getting 87.188.XXX.XXX. This is the one I need to get in the console.

Any ideas on which command i could use to get the right ip?

Thanks on advance.

I know I got quite rusty when it comes to bash coding, especially the more elaborate needed trickery handling awk or sed parts.

I do have a script that logs the IP address currently in use for the interwebs.

It gets that by either using wget -q0 URL or lynx -dump URL.

The most easy one was a site that only returned the IP address in plain text and nothing else. Unfortunately that site no longer exists.

The code was simple as can be: IP=$(wget -qO - http://cfaj.freeshell.org/ipaddr.cgi) But alas! using the code returns nothing cause the site is gone, as lynx can tell us:

I have a list of proxy addresses that I am randomly choosing from and feeding into a SplashRequest within a Scrapy spider. To confirm that this was working, I decided to try to scrape the results from What Is My IP?. As proxies were randomly chosen, I noticed three different responses based on the IP:

1. 502 Bad Gateway
2. 200 OK where the body says "Sorry, whatismyip.com is not available because it is categorized as security.nettools."
3. 200 OK with the correct proxy address being returned

If anyone could explain to me what is going on in #1 and #2 that would be much appreciated!

Edit

I have a Splash instance in a Docker container, and I am creating a SplashReqeuest (not a scrapy request) and feeding it a proxy IP chosen at random. For some IPs, I am able to confirm that it is being passed through to the request (see item 3), so that seems to validate this approach -- the random proxy IP is being fed through to the SplashRequest. However, for some of the IPs, I get a 502 Bad Gateway or that weird 200 Ok where "What Is My IP" doesn't return the IP.

The result are consistent for a given IP address i.e. if address X gives result 1, it always gives result 1.

As I understood,
In order to initialize P2P connectivity via hole-punching, a device should reside in a non-symmetric NAT (which basically also implies single WAN\External IP Address for outgoing traffic).

I can not find an android app (kind of a little tester app, to open when I'm inside a LAN) that tells what are all or some of my WAN\External IP Addresses.
All apps on Play that I found show me only one External IP Address, even though I test it from Symmetric NATs with multiple WAN\External Addresses.

An easy and quick suggestion would be nice (surfing to multiple "whatismyip" sites each time I want to test it is not easy nor elegant\quick).
