Answer 1

not sure if you still have this issue seeing as this question is over 6 months old, but here are the codes that work for me:
Redirecting the url:
RewriteCond %{HTTP_HOST} !^www.example.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
Redirecting the IP address:
RewriteCond %{HTTP_HOST} ^XXX\.XXX\.XXX\.XXX
RewriteRule (.*) http://www.yourdomain.com/$1 [R=301,L]
Your last piece of code is to avoid attacks by botnet scripts that automatically look for vulnerabilities in your software.
They are sometimes identified as User-Agent libwww-perl, and that's why you are supposed to disallow access from User-agent Libwww-perl.
As to how to test that I'm not sure of unfortunately.
