   What is the best redirection to add for Google rating during the maintanance time.Currently we are adding the following lines during maintanance.

    RewriteEngine on
    RewriteCond %{REMOTE_ADDR} !^192\.168\.
    RewriteRule /splash/index.html / [R=301,L]

    Google is threatening to remove some sites from their ranking completely due to this.

If you're doing some maintenance and your site is not available, HTTP 503 Service Unavailable should be the more appropriate status code.

If you're on apache 2.2, you could use
RewriteEngine on
RewriteCond %{REMOTE_ADDR} !^192\.168\.
# only /splash/index.html? /foo/bar should be served?
RewriteRule /splash/index\.html - [R=503]

So you're not on apache 2.2 but on an older branch, hence you can't issue a 503 with mod_rewrite.

What you can do is to rewrite (internally) to some script, e.g. php or perl or whatever and use the header/status functions to set a http status code provided by the language of you choice.
RewriteEngine on
RewriteCond %{REMOTE_ADDR} !^192\.168\.
RewriteRule /splash/index\.html /internal-script.php [L]
