The info in the Echo Request must be returned in the Echo Reply to your ISP - what that information is, I don't have a clue. But, since it's from your ISP, I'd guess that they're checking to make sure that it's still your equipment that's connected to their network.
My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.

The echo request is an ICMP wish sends a packet of data that the datato be sent back in Echo Reply.
The Echo Reply data must be the same as the Echo Request wish means that there is no problem in the connectivity between u and the ISP.
the data is mostly a series of bits amd mostly means nothing.
It is just to check the connectvity.
