This bug was introduced in v0.20.1 Now the behavior is as expected: first check hosts file, if it contains address - short return without querying nameservers. https://github.com/eventlet/eventlet/issues/387
The tests are intended to be run using Nose. http://somethingaboutorange.com/mrl/projects/nose/ To run tests, simply install nose, and then, in the eventlet tree, do: $ nosetests That's it! Its output is the same as unittest's output. It tends to emit a lot of tracebacks from various poorly-behaving tests, but they still (generally) pass.
