> In order to avoid information leakage to a public search index or web archive, it should be possible to configure Nutch in a way that no content is fetched from localhost, loop-back addresses, private address spaces.
> NUTCH-2527 adds the configuration snippets to exclude URLs pointing to private addresses. 
> However, filtering URLs isn't enough because a DNS entry of an arbitrary host name may point to a private IP address. Blocking must happen on the protocol level because the IP address is only know in the protocol implementation. I'll add an implementation for protocol-okhttp.
