-Determine the destination IP Address
-Send a UDP packet to the local DNS server
-Local DNS Server knows the desination host's IP address
-Sends a DNS response back to the sending host
-Local DNS server dose not know the destination IP address
-Send a seconds UDP packet to the next highest DNS host,
and so on, until the destination host's IP address is determined
