Hi,

Additional info.

Zone file (registrar's web panel):

@ 10800 IN A <public ip>
www 10800 IN A <public ip>
@ 10800 IN AAAA <public ipv6>
@ 10800 IN MX 10 <boxname>.<domain name>.

Name servers (registrar's web panel):

DNS1: a.dns.<registrar's domain>
DNS2: b.dns.<registrar's domain>
DNS3: c.dns.<registrar's domain>

I guess that this is the cause of the problem.
Should I add my name server here (i.e. <boxname>.<domain name>)?
Should I remove the existing name servers?

These servers will appear in the last output of dig.

$ dig +norec ns <domain name> @a.root-servers.net

[...]

$ dig +norec ns <domain name> @<name server from the previous AUTHORITY SECTION>

[...]

;; AUTHORITY SECTION:

<domain name>. 86400 IN NS c.dns.<registrar's domain>.
<domain name>. 86400 IN NS b.dns.<registrar's domain>.
<domain name>. 86400 IN NS a.dns.<registrar's domain>.

Let's pick one of them:

$ dig +norec ns <domain name> @c.dns.<registrar's domain>.

[...]

;; flags: qr aa; QUERY: 1, ANSWER: 3, AUTHORITY: 0, ADDITIONAL: 0

[...]

;; ANSWER SECTION:
<domain name>. 10800 IN NS a.dns.<registrar's domain>.
<domain name>. 10800 IN NS b.dns.<registrar's domain>.
<domain name>. 10800 IN NS c.dns.<registrar's domain>.

Let's pick another one:

$ dig +norec ns <domain name> @a.dns.<registrar's domain>.

(The output is the same.)

One more time:

$ dig +norec ns <domain name> @b.dns.<registrar's domain>.

(Same output.)

I thought that I should be able to see my own name server in the
output (i.e. <boxname>.<domain name>.) Is this correct?

/etc/bind/db.<domain name>:

$TTL 604800
<domain name>. IN SOA <boxname>.<domain name>. <user>.<domain name>. (
2 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
<domain name>. IN NS <boxname>.<domain name>.
;
<domain name>. IN MX 10 <boxname>.<domain name>.
<boxname> IN A <public ip>
www IN A <public ip>
<domain name>. IN AAAA <public ipv6>

/etc/bind/db.<last octet>:

$TTL 604800
$ORIGIN <reversed public ip (three octets)>.IN-ADDR.ARPA.
@ IN SOA <domain name>. <user>.<domain name>. (
2 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
IN NS <boxname>.<domain name>.

/etc/bind/named.conf.local:

zome "<domain name>" {
type master;
file "/etc/bind/db.<domain name>";
};

zone "<reversed public ip>.in-addr-arpa" {
type master;
notify no;
file "/etc/bind/db.<last octet>";
};


Cheers
