win-inet-pton

1.1.0 verified Fri May 01 auth: no python

Provides native inet_pton and inet_ntop implementations for Windows using ctypes. Version 1.1.0 is current; maintenance mode with rare updates.

pip install win-inet-pton

Common errors

error ImportError: No module named win_inet_pton ↓

cause Library not installed via pip.

fix

Run pip install win-inet-pton (note hyphen in package name).

error AttributeError: module 'socket' has no attribute 'inet_pton' ↓

cause Import succeeded but monkey-patching was not performed.

fix

After importing, assign: socket.inet_pton = inet_pton (and optionally inet_ntop).

error OSError: [WinError 10042] An address incompatible with the requested protocol was used ↓

cause Using `socket.inet_pton` with an incorrect address family or invalid address string.

fix

Ensure you pass the correct family (socket.AF_INET or socket.AF_INET6) and a valid IP string.

Warnings

gotcha This library is Windows-only. Importing it on non-Windows systems will raise an ImportError unless you guard it. Always use the check `if sys.platform == 'win32':` before importing. ↓

fix Wrap import in a platform check.

gotcha The library monkey-patches the built-in socket module. If you assign the functions via `socket.inet_pton = inet_pton`, ensure you do it only once to avoid double-patching. Doing it repeatedly is harmless but confusing. ↓

fix Apply the patch in a single location, e.g., at the start of your application.

deprecated Python 3.4+ on Windows includes official `inet_pton` support in the socket module. This library is only needed for Python 2.7 or earlier Python 3 versions. For modern Python, consider dropping it. ↓

fix For Python 3.4+, remove the dependency; the functions are built-in.

Imports

inet_pton
```
from win_inet_pton import inet_pton
```
Standard import after installing win-inet-pton.
inet_ntop
```
from win_inet_pton import inet_ntop
```
Standard import for inet_ntop.
socket
wrong
```
from win_inet_pton import socket
```
correct
```
import socket; socket.inet_pton = inet_pton
```
Do not import socket from win_inet_pton; instead assign the function to socket.inet_pton.

Quickstart

Monkey-patches socket module on Windows so inet_pton and inet_ntop work the same as on Unix.

import socket
from win_inet_pton import inet_pton, inet_ntop

# Monkey-patch socket module to add missing functions on Windows
socket.inet_pton = inet_pton
socket.inet_ntop = inet_ntop

# Now you can use inet_pton and inet_ntop directly via socket
print(socket.inet_pton(socket.AF_INET, '8.8.8.8'))
