Errors on specific IP addresses

[SteveBattista]

I get a timeout error on 65.49.0.0 - 65.49.127.255 (Hurricane Eletric) I get a stream did not contain valid UTF-8 error on 185.73.124.0 - 185.73.124.255 (jaredltd noc in LV) It will require loading the output of the results into a Vec then performing a from_utf8_lossy(v: &'a [u8]) -> Cow<'a, str>

I'm looking though the code to see why this could be so, I don't know why these occur or how to fix them.
