Does Windows XP support IPv6?

On Windows XP with Service Pack 1 (SP1) and later, this new command-line tool was enhanced to support the configuration and management of IPv6. This enhanced tool is the “netsh interface ipv6” command.

What is Sock_raw?

A raw socket is a type of socket that allows access to the underlying transport provider. To use raw sockets, an application needs to have detailed information on the underlying protocol being used. Winsock service providers for the IP protocol may support a socket type of SOCK_RAW.

What is TCP IP Winsock?

In computing, the Windows Sockets API (WSA), later shortened to Winsock, is an application programming interface (API) that defines how Windows network application software should access network services, especially TCP/IP.

What two things constitute a TCP IP socket?

A socket is one endpoint of a two-way communication link between two programs running on the network. A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to. An endpoint is a combination of an IP address and a port number.

What is the difference between connected and unconnected sockets?

The distinction is between connected and unconnected sockets. An unconnected socket can be used to communicate with any host; but a connected socket, because it has a dedicated destination, can send data to, and receive data from, only one host.

Is Winsock UDP or TCP?

The User Datagram Protocol is an alternative to TCP. Sometimes you see the term “TCP/IP” used to refer to all basic Internet technologies, including UDP, but the proper term is UDP/IP, meaning UDP over IP. Winsock gives you a UDP socket when you pass SOCK_DGRAM as the second argument to socket() .

What is Winsock used for?

A Windows sockets (Winsock) is an application programming interface (API) that allows for communication between Windows network software and network services, such as Transmission Control Protocol/Internet Protocol (TCP/IP).

How can I listen on more than one port at a time?

For TCP, no. You can only have one application listening on the same port at one time. Now if you had 2 network cards, you could have one application listen on the first IP and the second one on the second IP using the same port number. For UDP (Multicasts), multiple applications can subscribe to the same port.

Where is IPPROTO _ IPv6 socket option in Win32?

The IPPROTO_IPV6 socket options are defined in the Ws2ipdef.h header file which is automatically included in the Ws2tcpip.h header file. The Ws2def.h and Ws2ipdef.h header files should never be used directly. The IP_ORIGINAL_ARRIVAL_IF socket option is supported on Windows Server 2008 R2 as well as on Windows 7.

Where do I find IPPROTO _ TCP in win 10?

This option is available starting with Windows 10, version 1709. In the Microsoft Windows Software Development Kit (SDK) released for Windows Vista and later, the organization of header files has changed and IPPROTO_TCP level is defined in the Ws2def.h header file which is automatically included in the Winsock2.h header file.

What is the protocol of IPPROTO _ IP?

A protocol of IPPROTO_RAW implies enabled IP_HDRINCL and is able to send any IP protocol that is specified in the passed header.

What are the socket options for IPv4 and IPv6?

The following table describes IPPROTO_TCP socket options that apply to sockets created for the IPv4 and IPv6 address families (AF_INET and AF_INET6) with the protocol parameter to the socket function specified as TCP (IPPROTO_TCP). See the getsockopt and setsockopt function reference pages for more information on getting and setting socket options.
