Domain Mapping Trouble- "IP not set by admin yet."

Hello we are trying to set up Domain Mapping on our community site. I have done this before and got it to work, but for some reason I am having trouble and getting a message "IP not set by admin yet.", and cannot add a custom domain.

We are trying to map lesbianfilipina.com to lesbianfilipina.lesbian.com.ph.

By the way these are NOT porn sites. They are local community websites for lesbians and bisexual women in the Philippines.

I am sure the answer is simple but do not want to spend an hour or so figuring it out if someone else knows what is wrong with the setup.

Thanks,
Sean
