Overview

IPForce is a Python library that provides HTTP adapters for forcing specific IP protocol versions (IPv4 or IPv6) during HTTP requests. It's particularly useful for testing network connectivity, ensuring compatibility with specific network configurations, and controlling which IP protocol version is used for DNS resolution and connections.

Installation

Source Code

• Download Version 0.2 or Latest Source
• pip install .

PyPI

• Check Python Packaging User Guide
• pip install ipforce==0.2

Usage

Enforce IPv4

Use when you need to ensure connections only use IPv4 addresses, useful for legacy systems that don't support IPv6, networks with IPv4-only infrastructure, or testing IPv4 connectivity.

from ipforce import IPForceAdapter, IPVersion, IPForceMethod
import requests

session = requests.Session()
adapter = IPForceAdapter(IPVersion.V4, IPForceMethod.LOCK)
session.mount('http://', adapter)
session.mount('https://', adapter)

response = session.get('https://ifconfig.co/json')

Enforce IPv6

Use when you need to ensure connections only use IPv6 addresses, useful for modern networks with IPv6 infrastructure, testing IPv6 connectivity, or applications requiring IPv6-specific features.

from ipforce import IPForceAdapter, IPVersion, IPForceMethod
import requests

session = requests.Session()
adapter = IPForceAdapter(IPVersion.V6, IPForceMethod.LOCK)
session.mount('http://', adapter)
session.mount('https://', adapter)

response = session.get('https://ifconfig.co/json')

Using IPForceSession

from ipforce import IPForceSession, IPVersion

with IPForceSession(IPVersion.V4) as session:
    response = session.get('https://ifconfig.co/json')

Available Methods

Method	Description
IPForceMethod.LOCK	Thread-safe — global lock serialization (default)
IPForceMethod.GLOBAL	Non-thread-safe — temporary getaddrinfo patch

Direct Class Usage (Deprecated)

The following direct class usage still works but is deprecated in favor of the unified API above:

from ipforce import IPv4LockAdapter, IPv6LockAdapter

session = requests.Session()
session.mount('http://', IPv4LockAdapter()) # or IPv6LockAdapter()
session.mount('https://', IPv4LockAdapter()) # or IPv6LockAdapter()
response = session.get('https://ifconfig.co/json')
