Fedora , dns in Lame strežniki

[jest at softraja.com]

Živjo!

Verjetno miljon krat predelana tema. Meni se v zadnjem času dogaja, da
dobivam v log datotekah nekaj takega kot:

Dec  2 12:16:01 tower named[4398]: lame server resolving 'xxxx.com' (in
'xxx.com'?): 212.93.228.xx#53
Dec  2 12:30:21 tower named[4398]: lame server resolving 'sms-xxxx.net'
(in 'sms-xxx.NET'?): 193.77.103.xxx#53
Dec  2 13:07:33 tower named[4398]: lame server resolving 'xxx.com' (in
'xxx.com'?): 212.93.228.xx#53
Dec  2 14:28:09 tower named[4398]: lame server resolving 'www.slo-xxx.com'
(in 'slo-xxx.com'?): 193.77.206.xx#53

Mogoče kak pameten nasvet, oz. kaj ??
SW:
Fedora
