Is 576 bytes the safe size for UDP payload to eliminate fragmentation? -

-

the safe size of datagram packet (considering mtu such packet not fragmented) said 576 bytes ipv4 , 1500 ipv6.

  1. is correct ?

  2. if having connection machine server in country, 2 of communicate using udp, maximum (safest) payload size should have udp packet, 1500 or 576 ?

thank you

  1. no. that's safe size of total ip packet.
  2. 534.
