Network 127.0.0.1 vs 0.0.0.0

Which one should I use in '/etc/hosts'?
Please explain in details.

Random quotes on the topic:
Quote:
When you use the 0.0.0.0 method it doesnt try connect anywhere. But if you use 127.0.0.1 it actually tries to connect to a service on your computer which makes it take longer and use up more resources. Also you might run a webserver that it ask for invalid requests. Therefore it is better to use 0.0.0.0 than 127.0.0.1 as you want to kill the connection not to loop it back to your computer
Quote:
Why is it better? 0.0.0.0 doesn't connect anywhere. 127.0.0.1 does. If I run a web server that has a virtual host with the same domain name, it would serve the request.
Quote:
What does that have to do with 0.0.0.0? 0.0.0.0 has NO meaning on Linux, FreeBSD, or Mac OS-X and causes problems on those operating systems. The added benefit of using 127.0.0.1 is that the top phttpd (Pseudo HTTP Daemon) and Homer log what is being stopped and why.

I have tested both ways in Windows XP and Windows Server 2003 only, and all I can tell so far is that using a template in this form:
127.0.0.1 google-analytics.com
127.0.0.1 ssl.google-analytics.com
is not good at all for my system, and it can slow down even the most common operations.

But I have found that using a template in this form:
0.0.0.0 google-analytics.com
0.0.0.0 ssl.google-analytics.com
seems to be ok as far as system stability is concerned, and even the webpages are loading faster.

NAME
bup-web - Start web server to browse bup repositiory SYNOPSIS
bup web [[hostname]:port] DESCRIPTION
bup web starts a web server that can browse bup repositories. The file hierarchy is the same as that shown by bup-fuse(1), bup-ls(1) and bup-ftp(1). hostname and port default to 127.0.0.1 and 8080, respectively, and hence bup web will only offer up the web server to locally running clients. If you'd like to expose the web server to anyone on your network (dangerous!) you can omit the bind address to bind to all avail- able interfaces: :8080. EXAMPLE
$ bup web Serving HTTP on 127.0.0.1:8080... ^C $ bup web :8080 Serving HTTP on 0.0.0.0:8080... ^C SEE ALSO
bup-fuse(1), bup-ls(1), bup-ftp(1), bup-restore(1) BUP
Part of the bup(1) suite. AUTHORS
