how to fix .htaccess - redirect http://408.111.1111.domain.us/ to http://domain.us/index.php?w=408.111.1111

Question

We want to use mod_rewrite and .htaccess to do a redirect. How do we redirect http://408.111.1111.domain.us/ and www.408.111.1111.domain.us/ to http://domain.us/index.php?w=408.111.1111 ? If the original URL has a dash in place of the periods, or no periods in front of '.domain.us', it works fine. Wildcard domains work fine.

Here is our .htaccess file:

RewriteEngine On
Options +Followsymlinks
RewriteBase /
RewriteCond %{HTTP_HOST} .
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{REQUEST_FILENAME} !^.*/images/.*$
RewriteCond %{REQUEST_FILENAME} !^.*/uploads/.*$
RewriteCond %{HTTP_HOST}<>%{REQUEST_URI} ^([^.]+)\.rmwy\.us(:80)?<>/([^/]*) [NC]
RewriteCond %1<>%3 !^(.*)<>\1$ [NC]
RewriteRule   ^(.*)$ - [E=BLOGUSER:%1]
RewriteCond %{ENV:BLOGUSER} ^(.+)$
RewriteRule ^$ /index.php?w=%1 [L]
RewriteCond %{ENV:BLOGUSER} ^(.+)$
RewriteRule ^page([0-9]+)/([^/]+)?$ /index.php?w=%1&page=$1$2 [L]

My poor eyes are too tired to read through your .htaccess file but regarding your basic request for code that rewrites xyz.domain.us to domain.us/index.php?w=xyz, it would look something like this:

RewriteCond %{HTTP_HOST}          !^domain\.us [NC]
RewriteCond %{HTTP_HOST}          !^$
RewriteCond %{HTTP_HOST}          (www\.)?([0-9.]+)\.domain\.us
RewriteRule ^.*$                  http://domain.us/index.php?w=%2 [L,R=301]

You could then expand this to cater for different file paths (e.g. /friends/xyz) by using different RewriteRules.
