I have some name address that i want to send straight to the void using the HOSTS file but i don't want to use the 127.0.0.1. How can i do that?.

Why?, I want to speed up some proccess but 127.0.0.1 is serving a webserver, so if i use 127.0.0.1 then this process will call my webserver, consuming resources and may be delaying the process.

Right now, i am using 0.0.0.0 instead of 127.0.0.1 but i am not sure if it is correct.

    0.0.0.0  crl.microsoft.com

Two things:

  • Is your web server listening on 127.0.0.2 as well?
  • 0.0.0.0 should be fine, though you're likely generating some short-lived network traffic with it.

    Your first point was going to be my answer too. There are hundreds of loopback addresses, and only one of them is ever used in 99.99% of cases. – Mark Henderson Jun 11 '12 at 21:48

    @MarkHenderson a bit more then hundreds. You have an entire /8 there is 16,777,214 possible addresses. – Zoredache Jun 12 '12 at 0:00
