TCP/IPv6 Architectural Model (Windows Embedded CE 6.0)
1/6/2010
Windows CE .NET 4.1 and later uses a dual-stack architecture to support 32-bit IPv4 addresses and 128-bit IPv6 addresses. The type of destination IP address used determines which TCP/IP stack is used. For more information about the TCP/IP stack, see IPv6 and IPv4 Coexistence and Dual Stack Architecture.
For general information about how TCP/IP fits into the architecture that Windows Embedded CE uses for communications, see TCP/IP Architectural Model.
