Some Public IP's are unable to ping


When I ping some public IP’s, it’s not pinging.
Can u help me out of this.

Please show the output of the failed ping. Something like:

# ping
PING ( 56(84) bytes of data.
64 bytes from icmp_seq=1 ttl=58 time=29.5 ms
# ping
PING ( 56(84) bytes of data.
--- ping statistics ---
9 packets transmitted, 0 received, 100% packet loss, time 8127ms

You say “some” pings. Could it be those hosts are configured with a firewall to not respond to pings.
