Connect Warehouse mobile devices portal to AOS using DNS name instead of IP Address

Hi,

editing NetTcpBinding_WHSMobileDevicesService in web.conf portal for mobile devices we introduce the AOS instance server but as it is not a good practice in a Microsoft environment I like to use DNS name instead of IP address coz the address of the server may change due to changes. I changed the IP with FQDN of the server but it did not work, Any way to do this ?

Thanks
