<Dt> Destination port number </Dt> <Dd> This field identifies the receiver's port and is required . Similar to source port number, if the client is the destination host then the port number will likely be an ephemeral port number and if the destination host is the server then the port number will likely be a well - known port number . </Dd> <Dd> A field that specifies the length in bytes of the UDP header and UDP data . The minimum length is 8 bytes because that is the length of the header . The field size sets a theoretical limit of 65,535 bytes (8 byte header + 65,527 bytes of data) for a UDP datagram . However the actual limit for the data length, which is imposed by the underlying IPv4 protocol, is 65,507 bytes (65,535 − 8 byte UDP header − 20 byte IP header). </Dd> <Dd> In IPv6 jumbograms it is possible to have UDP packets of size greater than 65,535 bytes . RFC 2675 specifies that the length field is set to zero if the length of the UDP header plus UDP data is greater than 65,535 . </Dd>

Total length field in udp packet header is the length of
