Hi,

I am trying to run following python script in my Raspberry Pi. What I want to do is to extract Public IP Address of my Raspberry. But I am getting NULL. Please advise.

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
from urllib.request import urlopen
import re

#Setup Where I will get my IP Address
url = 'https://whatismyipaddress.com/'
print ("Our Choosen IP Address Service Is: ", url)

#Open-up the IP url and Take Away the IP Address
request = urlopen(url).read().decode('utf-8')

#Extract the IP Address Only
ourIP=re.findall("\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}", request)
ourIP = str(ourIP)
print ("Our IP Address is: ", ourIP)
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Output, what I am getting:

Our Choosen IP Address Service Is:  https://whatismyipaddress.com/
Our IP Address is:  []
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Regards,
Soumen

You are not allowed to access that site using Python, if you look at the request you will see this:

Access Denied (AK1).  Contact support@whatismyipaddress.com

If you try whatismyip.com you get the same. That site says:

What Is My IP API
If you need data returned to you via script, we provide an API section where you'll be able to call each of our tools and get the output in txt, json, or xml. You'll need to sign up for our Gold Membership to gain access to our API. Read our API Quick Start Guide to get the API up and running and working for you.

But http://myexternalip.com is allowing you to get your external address using a script. Try that instead.

Oh ho,
Okay. Got your point. I need to get my public ip in such a way. Can you suggest any site where I can collect that with such process? Or can I access Google service for this? If that is possible, can you please suggest that code?

The myexternalip site is what you can use, a simpler python implementation (from that site) that is working:

import urllib
url = 'http://myexternalip.com/raw'
myip = urllib.urlopen(url).read()
print myip

@Gerwin Jansen:

Thank you for your guidance, but it is not working directly in Pi. I have changed as follows:

from urllib.request import urlopen
import re

#Setup Where I will get my IP Address
url = 'http://myexternalip.com/raw'
print ("Our Choosen IP Address Service Is: ", url)

#Open-up the IP url and Take Away the IP Address
myip = urlopen(url).read()

#Extract the IP Address Only
#ourIP=re.findall("\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}", request)
#ourIP = str(ourIP)
print ("Our IP Address is: ", myip)
--------------------------------------------------------------------------
But still a little problem is there. I am getting the ip as:

Our Choosen IP Address Service Is:  http://myexternalip.com/raw
Our IP Address is:  b'xxx.xx.xxx.xxx\n'

How to remove "b" and "\n" before and after that IP address? Any suggestion?

Did you try the code from my last comment? If you did, then show the error you get, 'it is not working' is not something we can help you with.

The last sample code is working on my Raspberry and it is giving back the IP address without the b and \n

@Gerwin Jansen:

Yes, When I tried your code, I am getting following error.

1.PNG
Then I replaced as "print (myip)". Now I am getting the following msg.

2.PNG
So, I replace that code as given in my last comment. It worked, only to remove "b" and "\n" from the returned string.
b'xxx.xx.xxx.xxx\n'

May be I am doing something wrong. I am now using the code I have given my last comment.
Please advise.

You are running a GUI on your Raspberry?

Your question states that you want to run a python script.

Anyway, your program can't find 'urlopen' - do you have "import url lib"?

RPI:/tmp # cat getip.py
import urllib
url = 'http://myexternalip.com/raw'
myip = urllib.urlopen(url).read()
print (myip)
RPI:/tmp # python getip.py 
www.xxx.yyy.zzz

RPI:/tmp #
