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........ 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... Anyway.. Normally if you can't Ping it and can't HTTP to a web server....
