Eu me deparei com um problema estranho. Talvez alguém saiba a resposta. Eu uso named-checkzone para verificar meu arquivo de zona.
O arquivo de zona a seguir exibirá ignorando dados fora da zona quando eu usar nomes de domínio totalmente qualificados:
$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.$
No entanto, com nomes relativos, essas mensagens não são exibidas como neste arquivo de zona:
$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.$
Alguém poderia explicar por que isso acontece?
O comando que eu digito é o seguinte sudo named-checkzone www.example.com /var/named/example.com.zone .
A saída do arquivo que contém os nomes de domínio totalmente qualificados (FQDN) é a seguinte:
