requests ignores no_proxy which contains a IPv6 CIDR
python requests supports a no_proxy environment variable with a IPv4 CIDR e.g.
e.g
+ export http_proxy no_proxy
+ http_proxy=http://localhost
+ python -c 'import requests.utils ; print(requests.utils.should_bypass_proxies("http://1.2.3.4", None))'
False
+ no_proxy=1.2.3.0/24
+ python -c 'import requests.utils ; print(requests.utils.should_bypass_proxies("http://1.2.3.4", None))'
True
but doesn't support a IPv6 CIDR e.g.
+ http_proxy=http://localhost
+ python -c 'import requests.utils ; print(requests.utils.should_bypass_proxies("http://[1:2:3::4]", None))'
False
+ no_proxy=1:2:3::/64
+ python -c 'import requests.utils ; print(requests.utils.should_bypass_proxies("http://[1:2:3::4]", None))'
False
Expected Result
For proxy to be bypassed if a the url matches the IPv6 CIDR in no_proxy
Actual Result
IPv6 CIDR ignored
Reproduction Steps
as above
