I just found something very concerning in my log files whereby my primary 
name server seems to have added a loopback (localhost) address which is NOT 
owned by us. Can someone please tell me more details on what the following 
lines mean and if I should be concerned with it:

ns_forw: query( Bogus LOOPBACK A RR 
(localhost: learnt (A=localhost:NS= 1 Time(s)
ns_forw: query( No possible A/AAAA RRs: 1 

And more important how to prevent my name servers from allowing outsiders to 
add localhost records to my servers?
