How to load host entries into Windows CE device


Host name resolution is the process of mapping a host name to an IP address. Windows CE TCP/IP can use HOST entries stored in the registry to resolve host names.

You can load HOST entries into the following registry. Other host addresses found by DNS and WINS servers are also cached in the same registry key.

HKEY_LOCAL_MACHINE\Comm\Tcpip\Hosts\<host name>
You need to create a host name key for each host entry you want to reference.
