Datagrams require fragmentation when their size exceeds the Maximum Transfer Unit (MTU) of the transmission medium. Datagrams may be fragmented by the sending host (all Internet Protocol versions) or an intermediate router (Internet Protocol Version 4 only). If a datagram must be fragmented, and the option is set, the datagram is discarded, and an Internet Control Message Protocol (ICMP) error message is sent back to the sender of the datagram.
Setting this property on a Transmission Control Protocol (TCP) socket will have no effect.
