Here's what the entry says: If someone requests the IP address for 202.Avirtual2.com I really need to look up the IP address for 202.184.153.99 So now I'll issue a request to the roots for the domain .99 to get their name servers. Naturally the roots will respond with NXDOMAIN. Basically, this line is _probably_ never referenced unless the previous admin was doing something really dumb. But, if it is, your going to be wasting time and bandwidth (yours and the root name server's) looking up something that will never be found.
