Domain Mapping IP Address

The domain mapping plugin works well except for one issue.

My WordPress 3 MU install is using subdomains for each additional website.

So I have my domain.tdl.

site1.domain.tdl

site2.domain.tdl

site3.domain.tdl

site4.domain.tdl

site5.domain.tdl

Etc.

I found that if I typed in a subdomain that didn’t exist, (nositehere.domain.tdl), it would redirect me to http://domain.tdl/wp-signup.php?new=nositehere which is the signup for with “nositehere” already prepopulated in the Username field. Pretty neat.

However, after installing domain mapping, when I try and visit my IP address (http://173.xxx.xxx.xxx/), it redirects me to http://domain.tdl/wp-signup.php?new=173.xxx.xxx.xxx with “173.xxx.xxx.xxx” already prepopulated in the Username field!

http://173.xxx.xxx.xxx/ should redirect to domain.tdl…

not redirect to http://domain.tdl/wp-signup.php?new=173.xxx.xxx.xxx

Please help!
