Troubleshot erronous BIND9 DNS Address entry
I setup a BIND9 DNS server in the LAN as a backend to Samba4 service. The
network address of my LAN is 192.168.2.0/24 and I statically specify the
IP address of DNS server as 192.168.2.144.
Unfortunately, there is another MIC on my DNS server (in fact, the DNS
server is a virtual box, the extra MIC is the virtual bridge). They are in
different network, the network address of the virtual bridge is
192.168.122.0/24.
I bind a domain name dc.foo.bar to the static address 192.168.2.144 in
/etc/named.conf. However, when I query the DNS information with host -t A
dc.foo.bar, two entries are returned, one is 192.168.2.144 while the other
is 192.168.122.1.
I don't want dc.foo.bar binds to 192.168.122.1, neither do I know how it
is added into the DNS service. How could I trouble shot the problem and
remove the erronous DNS address entry?
