Specifies the number of data bytes to be sent. The default is 56, which translates into 64 ICMP data bytes when combined with the 8 bytes of ICMP header data. The maximum allowed value is 65507 for IPv4 (65467 when -R or -T or Intermediate hops) or 65527 for IPv6, but most systems limit this to a smaller, system-dependent number.
