Hello @KF_VA ,
I'd advise following along with our article on self-authentication, or checking out this post in our Success Hub. If you have one account that will be associated with your domain, then CNAME will be the best option for self-auth. If you know your domain is being utilized on multiple accounts, then the TXT option would be best. You'll need to work with your IT, or whomever manages your domain to get the elements required for setting this up in your account.
