| IPProtectionLevel | Enables restriction of a IPv6 socket to a specified scope, such as addresses with the same link local or site local prefix.This socket option enables applications to place access restrictions on IPv6 sockets. Such restrictions enable an application running on a private LAN to simply and robustly harden itself against external attacks. This socket option widens or narrows the scope of a listening socket, enabling unrestricted access from public and private users when appropriate, or restricting access only to the same site, as required. This socket option has defined protection levels specified in the T:System.Net.Sockets.IPProtectionLevel enumeration. |
| IPv6Only | Indicates if a socket created for the AF_INET6 address family is restricted to IPv6 communications only. Sockets created for the AF_INET6 address family may be used for both IPv6 and IPv4 communications. Some applications may want to restrict their use of a socket created for the AF_INET6 address family to IPv6 communications only. When this value is non-zero (the default on Windows), a socket created for the AF_INET6 address family can be used to send and receive IPv6 packets only. When this value is zero, a socket created for the AF_INET6 address family can be used to send and receive packets to and from an IPv6 address or an IPv4 address. Note that the ability to interact with an IPv4 address requires the use of IPv4 mapped addresses. This socket option is supported on Windows Vista or later. |

| NoChecksum | Send UDP datagrams with checksum set to zero. |
| ChecksumCoverage | Set or get the UDP checksum coverage. |
| UpdateAcceptContext | Updates an accepted socket's properties by using those of an existing socket. This is equivalent to using the Winsock2 SO_UPDATE_ACCEPT_CONTEXT socket option and is supported only on connection-oriented sockets. |
| UpdateConnectContext | Updates a connected socket's properties by using those of an existing socket. This is equivalent to using the Winsock2 SO_UPDATE_CONNECT_CONTEXT socket option and is supported only on connection-oriented sockets. |

Specifies the type of socket that an instance of the T:System.Net.Sockets.Socket class represents.
| Enumerator | |
|---|---|
| Stream | Supports reliable, two-way, connection-based byte streams without the duplication of data and without preservation of boundaries. A |
| Dgram | Supports datagrams, which are connectionless, unreliable messages of a fixed (typically small) maximum length. Messages might be lost or duplicated and might arrive out of order. A T:System.Net.Sockets.Socket of type F:System.Net.Sockets.SocketType.Dgram requires no connection prior to sending and receiving data, and can communicate with multiple peers. F:System.Net.Sockets.SocketType.Dgram uses the Datagram Protocol (F:System.Net.Sockets.ProtocolType.Udp) and the F:System.Net.Sockets.AddressFamily.InterNetworkT:System.Net.Sockets.AddressFamily. |
| Raw | Supports access to the underlying transport protocol. Using the T:System.Net.Sockets.SocketTypeF:System.Net.Sockets.SocketType.Raw, you can communicate using protocols like Internet Control Message Protocol (F:System.Net.Sockets.ProtocolType.Icmp) and Internet Group Management Protocol (F:System.Net.Sockets.ProtocolType.Igmp). Your application must provide a complete IP header when sending. Received datagrams return with the IP header and options intact. |
| Rdm | Supports connectionless, message-oriented, reliably delivered messages, and preserves message boundaries in data. Rdm (Reliably Delivered Messages) messages arrive unduplicated and in order. Furthermore, the sender is notified if messages are lost. If you initialize a |
| Seqpacket | Provides connection-oriented and reliable two-way transfer of ordered byte streams across a network. F:System.Net.Sockets.SocketType.Seqpacket does not duplicate data, and it preserves boundaries within the data stream. A |
