Redirect (mod_alias) with RewriteRule (mod_rewrite) because they both get applied to the same URI and will clobber each others changes sometimes. Just stick with mod_rewrite because you have wordpress rules that already use it.# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^12\.34\.56\.789$
RewriteRule ^(.*)$ http://www.domainname.com/$1 [L,R=301]
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
