http://tracert.com/ can ping and resolve address, but i cant

Hello, Ive been trying to ping (www)rust.grayles.com (just a subdomain Ive made) via Tracert - Tracertoute, Ping and Web site performance monitoring. however despite the results being successful, no PC on my network can ping it etc

"

Code:

PING rust.grayles.com (176.9.113.7): 56 data bytes 64 bytes from 176.9.113.7: icmp_seq=0 ttl=113 time=95.589 ms 64 bytes from 176.9.113.7: icmp_seq=1 ttl=113 time=97.505 ms 64 bytes from 176.9.113.7: icmp_seq=2 ttl=113 time=95.805 ms 64 bytes from 176.9.113.7: icmp_seq=3 ttl=113 time=96.217 ms 64 bytes from 176.9.113.7: icmp_seq=4 ttl=113 time=97.827 ms  --- rust.grayles.com ping statistics --- 5 packets transmitted, 5 packets received, 0% packet loss round-trip min/avg/max/stddev = 95.589/96.589/97.827/0.908 ms

Code:

"C:\Users\PC>ping rust.grayles.com
Ping request could not find host rust.grayles.com. Please check the name and try
 again."

Is what i get when i try to ping on CMD.

Can someone help me troubleshoot please? The address it should lead to is "176.9.113.7"
