I came across a strange problem. Maybe someone knows the answer. I use named-checkzone to check my zone file.

The following zone file will display ignoring out-of-zone data when I use fully qualified domain names:

$TTL 30
@ IN SOA localhost. admin.example.com. (
2017072702      ; serial
3               ; refresh
1               ; retry
2               ; expire
1M)             ; negative TTL
                        IN NS localhost.;
www.example.com.     IN A 192.168.111.45
www.example.com.     IN AAAA fe80::22c9:d0ff:1ecd:c0ef
foo.example.com.        IN A 192.168.121.11
bar.example.com.     IN CNAME www.example.com.
;generate 100 hosts
$GENERATE 1-100 host$.example.com. IN A 10.20.45.$

However with relative names no such messages are displayed as in this zone file:

$TTL 30
@ IN SOA localhost. admin.example.com. (
2017072702      ; serial
3               ; refresh
1               ; retry
2               ; expire
1M)             ; negative TTL
                        IN NS localhost.;
www     IN A 192.168.111.45
www     IN AAAA fe80::22c9:d0ff:1ecd:c0ef
foo     IN A 192.168.121.11
bar     IN CNAME www.example.com.
;generate 100 hosts
$GENERATE 1-100 host$ IN A 10.20.45.$

Could someone explain why that is so?

The command I enter is the following sudo named-checkzone www.example.com /var/named/example.com.zone.

The output for the file containing the fully qualified domain names (FQDN) is as follows:

/var/named/example.com.zone:11: ignoring out-of-zone data (foo.example.com)
/var/named/example.com.zone:12: ignoring out-of-zone data (bar.example.com)

zone www.example.com/IN: loaded serial 2017072702
OK

The output for the file containing the relative domain names is as follows:

zone www.example.com/IN: loaded serial 2017072702
OK
0

The command was wrong. Instead of the FQDN the first parameter has to be the zone:

sudo named-checkzone example.com /var/named/example.com.zone
