Easy, question..
Sure I could do that, I could run NMAP, Nessus, or any number of probes
to check the validity of the host reachability. N-Stealth... and the =
list goes on.
BUT if a host is denying pings from the world round and it stops trace a =
couple hops away
maybe a BOGON filter or ACL or........=20
Well If I can't http to it, and I can't ping it from multiple peering =
points, there
is a filter somewhere..  It can't even be accessed via the Worldcom =
UUNet network..
HMMMM..
Yeah you can telnet to it... Yeah I got to it via telnet...=20
Anyway.. Normally if you can't Ping it and can't HTTP to a web =
server....
