The less than check for ip_interface behavior seems weird. I am not sure if this is by design. We are just comparing the network address but when network address is equal we should compare the ip address.
The expectation is if a < b is False then b <= a must be True
>>> import ipaddress
>>> a = ipaddress.ip_interface("1.1.1.1/24")
>>> b = ipaddress.ip_interface("1.1.1.2/24")
>>> a < b
False
>>> b <= a
False
>>> a == b
False
>>>
This happens with both v4 and v6
The tests were passing because in ComparisonTests we were testing with prefix length of 32 which means the whole ip address became the network address.
I have made a fix here:
https://github.com/s-sanjay/cpython/commit/14975f58539308b7af5a1519705fb8cd95ad7951
I can add more tests and send PR but before that I wanted to confirm the behavior.

Indeed, this looks as a bug. >>> a < b False >>> b > a True |

Serhiy, just checking whether this needs backport? The PR has the backport to 3.5 and 3.6 labels, but it's not indicated in this ticket. If it doesn't need backport, then perhaps we can close this issue. Thanks. |

I think we should backport this to at least 3.6. |
