(2) Problems:

1. If I try to ping using a host name I get a msg stating, "Couldn't resolve host name". The only way I can get it to plot anything is to use an IP address. Why?

2. I am trying to ping IP 216.109.117.107 which should be yahoo.com. There are (14) Hops. The first (13) Hops show 100% packect loss. The first (13) hops do not display IP address or DNSName. Why?
