Yes, urllib3 does support IPv6. urllib3 is a powerful HTTP client for Python that works with many HTTP-related tasks. It uses Python's built-in http.client (formerly httplib in Python 2), which supports IPv6.
To use IPv6 with urllib3, you simply need to use an IPv6 address or a hostname that resolves to an IPv6 address. Here's a basic example that demonstrates making a request to an IPv6 address with urllib3:
import urllib3
# Create a PoolManager instance
http = urllib3.PoolManager()
# IPv6 address example, wrapped in square brackets
url = 'http://[2606:2800:220:1:248:1893:25c8:1946]/'
# Make a request to the specified IPv6 address
response = http.request('GET', url)
print(response.status)
print(response.data.decode('utf-8'))
In the example above, we're using a literal IPv6 address within the URL. The IPv6 address is enclosed in square brackets ([...]) to differentiate it from the port number.
When using a hostname, DNS resolution will take care of determining whether the address is IPv4 or IPv6. If the system's DNS resolver returns an IPv6 address, urllib3 will use it just like an IPv4 address. Here's an example:
import urllib3
# Create a PoolManager instance
http = urllib3.PoolManager()
# Hostname that resolves to an IPv6 address
url = 'http://ipv6.google.com/'
# Make a request to the host
response = http.request('GET', url)
print(response.status)
print(response.data.decode('utf-8'))
Make sure that your network and operating system are configured to support IPv6. If they are not, you might encounter issues when trying to connect to IPv6 addresses.
In summary, urllib3 supports IPv6 out of the box, and you can use it just like you would with IPv4, provided that you have proper network support and configuration.
