I'm creating a Tracert program and am wondering if the value "buffer" used in the Ping payload really matters. Can it be anything, or do routers respond differently based on the contents of the buffer?
What about the other parts of an ICMP ping message? Don't Fragment, etc...

I found one sample that sets the buffer like this:
byte[] Buffer
{
get
{
if (_buffer == null)
{
_buffer = new byte[32];
for (int i = 0; i < Buffer.Length; i++)
{
_buffer[i] = 0x65;
}
}
return _buffer;
}
}
