I've heard pretty much the same thing as you did wrt. root name servers=20 denying AXFR, but as "it works" (TM), I don't see a reason not to use it. A= nd=20 it seems that the author of the FreeBSD default named.conf thought likewise= ,=20 which is pretty okay with me (from the experience I gathered this morning). By the way: using the roots as hints only adds to the number of requests yo= ur=20 server has to do in order to retrieve first-level domain name servers, so i= n=20 the end, the transmitted data should be way higher than doing one AXFR to=20 find them (simply because you'll see a large subset of those toplevel domai= ns=20 being requested when you're publically offering a DNS server). And the data= =20 is also cached on an AXFR in persistant storage, which is another major=20 benefit (for me). =2D-=20 Heiko Wundram Product & Application Development =2D------------------------------------ Office Germany - EXPO PARK HANNOVER =20 Beenic Networks GmbH Mail=E4nder Stra=DFe 2 30539 Hannover =20 =46on +49 511 / 590 935 - 15 =46ax +49 511 / 590 935 - 29 Mail wundram@beenic.net Beenic Networks GmbH =2D------------------------------------ Sitz der Gesellschaft: Hannover Gesch=E4ftsf=FChrer: Jorge Delgado Registernummer: HRB 61869 Registergericht: Amtsgericht Hannover
