What kind of hosting are you on? If you have cPanel there's a menu option to block IP addresses.
If you're not, the cheap and easy way to handle this is to block the IP in your .htaccess file. You'd add this up top:
Order Deny,Allow Deny from 126.96.36.199
But I don't know the importance of this site or want to make any assumptions. The real, ongoing fix for this issue is to purchase the web application firewall that comes with GoDaddy's Website Security Deluxe package. It automatically handles bot brute force attacks, and allows you to deny access from geographical regions.
