Resolving issue on specific domain

Hello

 

We are facing a weird issue while resolving a specific domain name from our
authoritative DNS server running on BIND 9.10.4-P1

Server has only one public IP address.

If you try to resolve the domain using either dig or nslookup you will not
get any result whereas if you specify @localhost you will get the answer

Do you have any explanation about this behavior and what should be done to
fix this issue?

Examples:

 

#dig @localhost soa domainname

 

; <<>> DiG 9.9.4-P1 <<>> @localhost soa domainname

; (2 servers found)

;; global options: +cmd

;; Got answer:

;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 46807

;; flags: qr aa rd; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 3

;; WARNING: recursion requested but not available

 

;; OPT PSEUDOSECTION:

; EDNS: version: 0, flags:; udp: 4096

;; QUESTION SECTION:

;domainname.                    IN      SOA

 

;; ANSWER SECTION:

domainname.             86400   IN      SOA     xx.idm.net.lb. y.domainname.
1468329403 10800 3600 604800 10800

 

;; AUTHORITY SECTION:

domainname.             86400   IN      NS      xx.idm.net.lb.

domainname.             86400   IN      NS      yy.idm.net.lb.

 

 

 

#dig soa domainname

 

 

; <<>> DiG 9.9.4-P1 <<>> soa domainname

;; global options: +cmd

;; Got answer:

;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 10964

;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1
