I was using the tool against same IPs like this:

cat ips | hakip2host > results

But I noticed some unexpected errors while it was running:

I am not sure if is should be considered normal or not. Where are this errors coming from? These are output to stderr

Same going on with me, I'll be waiting for an answer. Forgot to mention, that I had found a quick way of avoiding this, which would be redirecting the standard error to null.

I have no idea what's causing this sorry!
