Dúvidas DNS (Configuração)

[guardian_metal]

Segui as dicas do site para configurar o DNS (HOW TO DNS) e abaixo estão meus arquivos de configuração. Como sei se o DNS está funcionando?.

zone "lasertools.laser.br" {
type master;
file "zone/db.lasertools";
};

};

ps ax |grep named

[guardian_metal]

Digitei o comando que estava no artigo "HOW TO DNS" e o comando que o psy me passou e apareceu o seguinte:

"
[root@lasertools-serv root]# ps ax |grep named
817 ? S 0:00 [named]
3337 pts/1 S 0:00 grep named
[root@lasertools-serv root]# dig lasertools.laser.br

; <<>> DiG 9.2.1 <<>> lasertools.laser.br

Isso significa que o DNS está configurado e funcionando?.

[guardian_metal]

Fiz mais algumas mudanças, no resolv.conf em /etc eu coloquei "nameserver 192.168.172.4" e dei os comandos novamente e encontrei os resultados abaixo, preciso configurar mais algum arquivo ou o DNS ja está funcionando?.
