Destination net unreachable

I am having trouble pinging some servers from a ethernet connected PC. Most web sites work but when I ping a few I can not connect. I have used an android to ping the same sites on the same network and the ping works. I keep getting time outs or destination net unreachable
 
Use TRACERT whatever_site OR TRACERT whatever_ip_address

you will see that the network is the problem as the ping never reaches the desired target
 
It turned out to be the isps router trying to use same ip twice. Now I have issue with connecting with it at all. Isp tech Is coming on Tuesday. Nothing can connect to it wireless or wired. Tried pinging it from my phone with no response. Isp said they can ping router.
