Script in working

Description

If you're here, you may be faced with the challenge of finding out Google's current actual IP address ranges. Instructions on how to do this can be found at these links: How to find Google Workspace IP address ranges, How to get Google IP address ranges This python-script greatly simplifies and automates this work.

Installation

The script requires Python version 3.6 or higher. Of course, you need to install it yourself first Python. On Linux, it is usually already installed. If not, install it, for example:

$ sudo yum install python3
$ sudo dnf install python3
$ sudo apt install python3
$ sudo pacman -S python

Additionally, you will need a Python package installer, such as pip. You can install it on Linux like this:

$ sudo yum install python3-pip
$ sudo dnf install python3-pip
$ sudo apt install python3-pip
$ sudo pacman -S python-pip

For Apple macOS:

$ xcode-select --install

Install brew:

$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Install Python:

$ export PATH=/usr/local/bin:/usr/local/sbin:$PATH
$ brew install python

Note: brew

For Microsoft Windows download the distribution package and install it. I recommend downloading "Download Windows x86 executable installer" if you have a 32-bit OS and "Download Windows x86-64 web-based installer" if you have a 64-bit OS. During installation, I recommend checking all options (Documentation, pip, tcl / tk and IDLE, Python test suit, py launcher, for all users (requeres elevation)).

Previously, you may need to update pip itself (Python package installer):

$ python -m pip install --upgrade pip
or
> py -m pip install --upgrade pip

Installing and update dependencies

$ pip install -U requests
$ pip install -U dnspython
$ pip install -U colorama

and

$ pip install -U requests[socks]

or

$ pip install -U PySocks

If you are running Linux or macOS, and you plan to run the script as the current user, then additionally specify the --user option. In this case, the necessary dependencies will be installed into the home folder of the current system user and are available when launched from the task scheduler (cron) on behalf of this current user.

Depending on your Python environment, your actions will be slightly different, for example, you may need to specify the --user key (for pip) or use the python3 and pip3 commands instead of the python and pip commands. If you use virtual environments, then most likely, you will need to do all of these actions after entering the appropriate environment.

Global constants in the script

Some options are inside the script. There is no point in putting them in the parameters, since you only need to configure them once, and then successfully forget about them.

You can also set the values of global constants directly via operating system environment variables of the same name so as not to change the script itself.

How to add a script to Linux cron

To do this, create a crontab task that will be executed, for example, every midnight on behalf of the user (creating tasks as root is not the best idea):

Suppose your Linux username is: user

Your home folder: /home/user

The folder where this script is located: /home/user/py

To run the script directly, run the command:

$ chmod +x /home/user/py/get_google_ip_pull.py

Adjust in the first line of the script Shebang (Unix), eg:

Show the path where python is located:

$ which python

or

$ which python3

Correction python path in Shebang:

#!/usr/bin/python
#!/usr/bin/python3
#!/usr/bin/env python
#!/usr/bin/env python3

Rename script:

$ mv /home/user/py/get_google_ip_pull.py /home/user/py/get_google_ip_pull

Check script launch:

$ /home/user/py/get_google_ip_pull -h
$ /home/user/py/./get_google_ip_pull -h

If everything is fine, run the editor crontab, if not, go back to setting Shebang:

$ crontab -u user -e

Here user - is your Linux login

If you, like me, do not like vim (I have not seen a single person who is fluent in this editor, although it probably exists somewhere), you can edit the tasks in your favorite editor, for example:

$ EDITOR=nano crontab -u user -e
$ EDITOR=mcedit crontab -u user -e

or

$ VISUAL=nano crontab -u user -e
$ VISUAL=mcedit crontab -u user -e

In the task editor, create something like this:

0 0 * * * /home/user/py/get_google_ip_pull -nb -pon -gh -spf -static -cloud -auth -e user@gmail.com -t -split >/dev/null 2>&1

or

0 0 * * * /usr/bin/python3 /home/user/py/./get_google_ip_pull.py -nb -gh -spf -static -cloud -auth -e user@gmail.com -t -split >/dev/null 2>&1

Specify the full paths to the data file and the script.

Note: cron

You can view created tasks for user user like this:

$ crontab -u user -l

Delete all tasks from user user, you can:

$ crontab -u user -r

How to add a script to Microsoft Windows Task Scheduler

Ask for help to documentation

Sample:

> schtasks /Create /SC DAILY /TN "Domain Expiration Checker" /TR "'с:\get_google_ip_pull.py' -nb -pon -gh -spf -static -cloud -auth -e user@gmail.com -t -split" /ST 23:59

Postscriptum

• The script was tested in Microsoft Windows 10/11, Linux Fedora 36/37, Linux Debian 9/10/11/12, Linux Ubuntu Desktop 18.04/20.04/20.10/22.04.2/23.04, CentOS Linux 7.9/8.5, Rocky Linux 8.8/9.2, Linux Manjaro 22.1.3, Apple macOS 13.4.1 Ventura on MacBook Pro M1.

• Sorry for my bad English. And on the other hand, which of you can boast of knowing the great and mighty Russian language? Have any of you read Pushkin, Tolstoy, Dostoyevsky, Gogol, Bulgakov in the original...? It's a joke.
• The program code of the script is not perfect. But please forgive me for that.
• Glory to the E = mc ² !
• I wish you all good luck!

A final plea

It's time to put an end to Facebook. Working there is not ethically neutral: every day that you go into work, you are doing something wrong. If you have a Facebook account, delete it. If you work at Facebook, quit.

And let us not forget that the National Security Agency must be destroyed.
