If you are using Apache and have mod_rewrite, you can ban them. Try this for starters:
Options +FollowSymlinks
RewriteEngine On
RewriteBase /
RewriteCond %{REMOTE_ADDR} "^63\.148\.99\.2(2[4-9]¦[3-4][0-9]¦5[0-5])$"
RewriteRule .* - [F,L]
This will issue a 403 Forbidden error code for your site for just their IP addresses.
