From the netselect v 0.3 README:
This is netselect, an ultrafast intelligent parallelizing
binary-search implementation of "ping."
Now stop laughing and pay attention.

The following saved output should be more informative (script courtesy

As to the original question, yes, I've successfully built netselect
using Cygwin. The "everything is 30 hops" results, however, I never
bothered to investigate further. Instead, I opted for the more
traditional pointy metal projectile hurled toward a concentrically
ringed object methodology, the results of which were validated by
pouring a pint of Guinness and making note of the decreasing number of
times I glanced at my watch during the download process.
