ok, i think you're mixing things

, to have a chaturbate subdomain (xxxx.chaturbate.com), you don't even need your own domain, just create the whitelabel without it
there are 3 ways you can do this, all have different results:
1. do fully what OP said, make a whitelabel on chaturbate and point your domain to the whitelabel ip (you need to add the domain name to the whitelabel when you set it up on chaturbate): the url of your site will be yoursite.com, in this case you can earn via revshare only and can link to a specific model's room
2. do partly what OP said, don't use a separate domain, but do create a whitelabel: the url of your site will be xxxx.chaturbate.com, in this case you can earn via revshare only and can link to a specific model's room
3. don't do what OP said at all, don't set up a whitelabel, but forward your domain to a selected tracking url: the url of your site will be a) the tracking url (
http://chaturbate.com//affiliates/in/xxxx/xxxx/?track=default) or b) yoursite.com if you use cloaking on the registrar, in both of these cases you will be able to earn per 1) free signup and 2) revshare too depending on the tracking url of your choice, but you won't be able to link to a certain model's room
i suppose you want to do exactly what OP suggested, in that case:
start making a whitelabel on chaturbate, so you'll get the ip you need to point your domain to, head over to your registrar, make sure the name servers are set up correctly, then create A records for 1) yoursite.com and 2)
www.yoursite.com with the ip address you're given by chaturbate, if you're done with this, head back to chaturbate and input your domain name into the appropriate field of the whitelabel setup page, so the result should be a whitelabel on yoursite.com, where you can link to a model's room by yoursite.com/broadcaster's_chaturbate_username
from the looks of it, if you already pointed your domain to the ip, you're only missing the part where you need to input your domain name into the setup page of the whitelabel
