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.... J

Is anyone from Alter.net lurking? Just for grins I went to the DIGEX looking glass and I could

not ping it

...

from MAE-Central, PAIX , MAE-East and also from AT&T Cerf router.... below are some of the traces.. Always dies on Alter... I wonder..... Alter?

Brilliant. Why did not you try "telnet <target.ip> 80"?

Just because random packets spewed by traceroute are dropped on the floor does not mean that the site is dead.
