Inatalled easily, worked right away, does what it says on the tin. Good.
The fact that it relies on an English ifconfig means it doesn't work in all cases, but at least it is clearly documented.
At least on the operating systems I care about this seems to work fine. The functionality is limited (I wish it'd give me mac addresses, too), but compared to some of the alternatives the API at least isn't insane.
Removing downvote because new maintainer has been made to see the light.
