Re: ping can't find addresses IP scan shows
IP scan probably doesn't relay just only on ICMP responces. It probably looks to ARP table too. If there is a device which uses IP stack but doesn't want to reply to ICMP echo request it must answer to ARP query(in other case it has no IP connectivity and it cannot communucate using IPv4 at all ). It measn ARP table is filled with IP/MAc pair of the device.
Re: ping can't find addresses IP scan shows
THIS is the perfect example to show people why refusing to reply to pings does NOT make you invisible on the network.
There are other ways.
At work, whenever a server admin requests an IP address for a new server, even when the documentation shows an address is available, I check the ARP cache on the gateway router before I completely consider the address clear... because if a host is dropping ping requests, it will not show up with a simple ping test.

This is my first (and probably last) win 10 PC, I guess it's refusing pings by default, I only had it on long enough to install some remote control programs.
When I turned it on after reading your reply it said my files were safe and then "we'll be ready soon", that was over an hour ago, looks like it's doing a big update, or a major melt down.
If it survives the reboot I'll see why it won't respond to pings.
I looked in my ARP table and found a dozen 169.254 addresses from my Nano station, never thought to see what was in there, thanks for the tip.

Yeah - Windows firewall drops pings by default when it's turned on.This is my first (and probably last) win 10 PC, I guess it's refusing pings by default, I only had it on long enough to install some remote control programs.
You can configure it not to do this if you like.
