Using wild card in robots

Can you add * to ip?

[walrus]

Disallow:
User-agent:63.148.99.*
Can you do this to block all combinations of the last part of an ip?

walrus,

I'm afraid you have confused robots.txt with .htaccess and other methods of access control.
The objects to be disallowed in robots.txt are robot names and resources -- such as pages -- on your site.

User-agent: Scooter
Disallow: /igi-bin/
Disallow: /private/

Try a search on WebmasterWorld for "mod_rewrite user_agent" or ".htaccess Deny", or if you're on an IIS server, "ISAPI rewrite".
