Fuzz IP.Is<property>() methods against stdlib net.IP equivalents

Open moreati opened this issue 4 years ago • 3 comments

The intent is to find discrepancies between netaddr.IP and net.IP. These don't necessarily indicate a bug (in either), but it's better to find them and explicitly document/exclude them.

Found 4 cases, again I'm not sure if a discrepancy is a bug or a facet I've not understood.

@moreati I just discovered this was still open and unmerged. Sorry about that. Any reason I shouldn't merge now?
