I will add my +1: NXDOMAIN does not mean "I don't have a number for that name but someone else might." It means "The DNS lists this name as having no number (or whatever)." There's no more reason to look further than if you got a positive answer from one server and still wondered if some oth

Hi, The google DNS server was only examples.. it can be some internal DNS servers and external DNS servers. For eg 10.10.10.10; 120.10.13.12 etc. where the DNS requests are being forwarded to.. There are issues with connectivity where the DNS entries are not synced up. And these entries are all sp

So your administrator is breaking DNS if all 3 servers have been added as NS records but the zone is not available on all 3 servers. Get him/her to fix your DNS hierarchy first then you wont need to check which server is hosting the subdomain. Steve On 30 May 2013 10:30, sumsum 2000 wrote: > Hi

Hi, This is a non-standard behavior and I would like to have the following: In the case where I am working on, /etc/resolv.conf contains localhost 127.0.0.1 and BIND is listening on localhost port 53 as non-authoritative DNS So all the requests are sent through 127.0.0.1 and based on the domai

Well you can do that. It does not change the fact that NXDOMAIN is a DEFINITIVE answer - it does not exist, there is no reason to look further. On 30/05/13 9:56, Ashok Agarwal wrote: > Sorry, its not */etc/hosts* file rather its */etc/resolv.conf*. > > > On Thu, May 30, 2013 at 1:25 PM, Ashok Ag

It's not possible. NXDOMAIN is NXDOMAIN, it doesn't exist, it doesn't mean try another server to see if you get lucky next time. Steve On 30 May 2013 08:26, sumsum 2000 wrote: > Hi, > I have the following change to be available from BIND9. > > I have zone forwarders as follows with BIND9 setup
