I am connected to internet by an proxy server in my university.
I can not ping the 64.233.187.99(
www.google.com) or nmap it
[hall4@HallfourServer hall4]$ ping 64.233.187.99
PING 64.233.187.99 (64.233.187.99) 56(84) bytes of data.
--- 64.233.187.99 ping statistics ---
22 packets transmitted, 0 received, 100% packet loss, time 21017ms
[hall4@HallfourServer hall4]$ nmap 64.233.187.99
Starting nmap V. 3.00 (
www.insecure.org/nmap/ )
Note: Host seems down. If it is really up, but blocking our ping probes, try -P0
Nmap run completed -- 1 IP address (0 hosts up) scanned in 54 seconds
[hall4@HallfourServer hall4]$
But the IP address is working well When i put it in mozilla browser.
Browser can resolve it.But Why does i can not ping or nmap it.?
Is there any way?
