Hi Prashant,

Thanks for getting in touch with us - I'd be happy to give some advice here!

In short, there are some devices/IP addresses that aren't configured to respond to ICMP echo requests - which is common with AWS and Azure targets.

The intermediate hops/devices are receiving what's called ICMP TTL Expired packets; different than an ICMP echo request, which is what the final destination is receiving. If you'd like to learn more, we cover this topic in more detail here:

- PingPlotter Port Use

I would recommend using either TCP or UDP in order to troubleshoot at this device/IP. If you'd like to use TCP, you'll need to install WinPcap (which gives PingPlotter the ability to generate TCP packets).

- Install WinPcap

Lastly, you can change your packet type to TCP or UDP in PingPlotter under Edit -> Options -> Packet.

I hope that helps - please let us know if you have any other questions!

All the best,
