[Web4lib] htaccess to block multiple IP addresses

[VanderHart, Robert]

I'm trying to block bots that don't obey the robots.txt directives.
We're using Linux/Apache 1.3.  I was wondering if the following syntax
is correct in an .htaccess file in our root directory:

<Limit GET POST>
  order allow,deny
  allow from all
  deny from 213.239.236.18
</Limit>

<Limit GET POST>
  order allow,deny
  allow from all
  deny from 65.19.150.232
</Limit>

1) Is this the only way to block several IP addresses from different
ranges?

2) Is there a more efficient way to block nasty robots?
