Generally, there are two steps to point your domain to StoreHippo:
Redirect your top domain e.g. example.com to www.example.com. If your domain provider does not support redirect then point the top level domain to StoreHippo Redirect Server at 22.214.171.124 which will automatically redirect the non-www domain to www.
Add CNAME for www.example.com to point to your StoreHippo URL e.g. example.storehippo.com.
