({{!IPv4=RFC0791}}), the DF bit MUST be set if possible, to prevent
fragmentation on the path.

Datagrams are required to be of a minimum size under some conditions. However,
the size of the datagram is not authenticated. Therefore, an endpoint MUST NOT
close a connection when it receives a datagram that does not meet size
constraints, though the endpoint MAY discard such datagrams.


## Initial Datagram Size {#initial-size}

payload that is smaller than the smallest allowed maximum datagram size of 1200
bytes. A server MAY also immediately close the connection by sending a
CONNECTION_CLOSE frame with an error code of PROTOCOL_VIOLATION; see
{{immediate-close-hs}}. When a client receives an ack-eliciting Initial packet
that is carried in a UDP datagram with a payload that is less than 1200 bytes,
that client MAY close the connection by sending a CONNECTION_CLOSE frame.

The server MUST also limit the number of bytes it sends before validating the
address of the client; see {{address-validation}}.
