Because Podbean.com uses a cluster of servers, there is no single fixed IP to be used for your Podbean site. Only CNAME record is supported for mapping your own domain name to your Podbean site. You may use your own domain name in these formats: www.mydomain.com or podcast.mydomain.com. The root domain name such as mydomain.com, is not supported if your domain service provider does not support CNAME for the root domain.
To set the CNAME record for your own domain, you can go to: http://support.podbean.com/customer/portal/articles/1725505-podbean-%7C-how-to-set-the-cname-dns-record-to-map-your-own-domain-to-your-podbean-site-on-godaddy-com
