Ping is a basic Internet program that lets you verify that a particular IP address exists and can accept requests. The verb ping means the act of using the ping utility or command. Ping is used diagnostically to ensure that a host computer you are trying to reach is actually operating.
Ping can also be used with a host that is operating to see how long it takes to get a response back. Using ping, you can learn the number form of the IP address from the symbolic domain name |

It's usually best to accept 1 or 2 for each IP then block any more from them for say 30 minutes. |
Code: |
On Ping from host, log host to host.log
Check host.log for number of pings If number of pings > 4 Then run deny.sh script rm hosts.log End |

in windows 2k pro, you can go and set up ipsec, to specifically deny, all ping requests to all ports. Its pretty cool. Check it out. |
