Home Questions Tags Users Unanswered Windows 2016 DNS server returns SERVFAIL for non-existing doma

I have two DNS resolvers in /etc/resolv.conf file. The top one is Windows DNS server, and the bottom one is my wi-fi router. Please see below. nameserver nameserver

In Windows DNS server, the sole "Forward Lookup Zone" is biman.net

When I query for host in the zone (biman.net) the Windows DNS server works fine-- either it returns the IP or NXDOMAIN. But when I query for anything for non-existing zone it returns SERVFAIL. But the wifi router returns NXDOMAIN even when zone name is bogus.

How can I get NXDOMAIN response from Windows DNS server when zone does not exist?

Below are the queries and the responses.
root@VDIkali:~# nslookup -q=A kali2.biman.net Server: Address:

Name: kali2.biman.net Address:

root@VDIkali:~# nslookup -q=A NOHOST.biman.net Server: Address:

** server can't find NOHOST.biman.net: NXDOMAIN

root@VDIkali:~# nslookup -q=A kali2.NONEXTING.net ;; Got SERVFAIL reply from, trying next server Server: Address:

** server can't find kali2.NONEXTING.net: NXDOMAIN

Net::DNS::RR::APL - DNS APL resource record SYNOPSIS
use Net::DNS; $rr = new Net::DNS::RR('name IN APL aplist'); DESCRIPTION
DNS Address Prefix List (APL) record METHODS
The available methods are those inherited from the base class augmented by the type-specific methods defined in this package. Use of undocumented package features or direct access to internal data structures is discouraged and could result in program termination or other unpredictable behaviour. aplist @aplist = $rr->aplist; @aplist = $rr->aplist( '1:', '!1:' ); @aplist = $rr->aplist( '1:', '2:FF00:0:0:0:0:0:0:0/8' ); @aplist = $rr->aplist( negate => 1, family => 1, address => '', prefix => 28, ); Ordered, possibly empty, list of address prefix items. Additional items, if present, are appended to the existing list with neither prefix aggregation nor reordering. Net::DNS::RR::APL::Item Each element of the prefix list is a Net::DNS::RR::APL::Item object which is inextricably bound to the APL record which created it. negate $rr->negate(0); $rr->negate(1); if ( $rr->negate ) { ... } Boolean attribute indicating the prefix to be an address range exclusion. family $family = $rr->family; Address family discriminant. prefix $prefix = $rr->prefix; Number of bits comprising the address prefix. address $address = $object->address; Address portion of the prefix list item. string $string = $object->string; Returns the prefix list item in the form required in zone files.
