Redirect IP address to domain name

Question

Not sure how it happened, but Google has indexed my site both by IP address and domain name and in some search in Google I see my site like 121.12.12.123/tech/tech.php.

Please let me know how can I redirect it to my domain?

121.12.12.123    redirect to   www.mydomain.com
121.12.12.123/*  redirect to   www.mydomain.com/*

If your site is running on a apache webserver, you could use mod_rewrite and put something like this in your .htaccess:

RewriteCond %{HTTP_HOST} ^121\.12\.12\.123
RewriteRule (.*) http://www.mydomain.com/$1 [R=301,L]
