bogus info for root NS (broadcast addr!)
Dear colleagues, rather nasty bogus info for NS.NIC.DDN.MIL is spreading, and your host already got it: ; <<>> DiG 2.0 <<>> @nic.funet.fi NS.NIC.DDN.MIL. any ;; ->>HEADER<<- opcode: QUERY , status: NOERROR, id: 10 ;; flags: qr rd ra ; Ques: 1, Ans: 2, Auth: 2, Addit: 2 ;; QUESTIONS: ;; NS.NIC.DDN.MIL, type = ANY, class = IN ;; ANSWERS: NS.NIC.DDN.MIL. 517916 A 192.112.36.4 NS.NIC.DDN.MIL. 131377 A 192.112.36.255 ;; AUTHORITY RECORDS: NIC.DDN.MIL. 205986 NS NIC.DDN.MIL.

Dear colleagues,
rather nasty bogus info for NS.NIC.DDN.MIL is spreading, and your host already got it:
Hello Ruediger, Try: dig -x 137.129.1.1 and then check your cache... Even though you seem to accept commonly happening faults in German DNS configurations, this one is in France... It took circa 30-40 minutes to get that fault to happen the first time after I restarted the dns server. Once I found that, French site, it is repeatable reliably :-( -- 5 minutes later, it seems I can't repeat that at all.. No, again... Now with "named -d 255", which gives somewhat more data.. There we are. Yes, we definitely get the contamination from 137.129.150.2 ( xdata.cnrm.meteo.fr, DNS manager: company@ctidev.cnrm.meteo.fr ) /Matti Aarnio <mea@nic.funet.fi> Postmaster
