When the Network Affiliates sign up, they need to fill in the network ID. FuseClick can generate the default application domain  according to the network id.
For example-networkid = “affiliate” and Default application domain= “affiliate.fuseclick.com”. If Network wants to use their own company name, it needs to buy a new domain name as an Application domain. The Domain name service provider allows you to check and assign available domain name. Once you get the available domain name, you can resolve it by using CNAME settings. After successful CNAME, Go to FuseClick systems -> General Settings -> Custom application domain. Fill in the new application domain and save the settings. Then you can use these new domains to login.
