Hi,
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(29.192.115.200.IN-ADDR.ARPA) Bogus LOOPBACK A RR
(localhost:127.0.0.1) learnt (A=localhost:NS=200.115.192.29): 1 Time(s)
ns_forw: query(29.192.115.200.IN-ADDR.ARPA) No possible A/AAAA RRs: 1
Time(s)
And more important how to prevent my name servers from allowing outsiders to
add localhost records to my servers?
Thanks,
SW
