    Alibaba Cloud DNS:Testar resolução de DNS

    Última atualização: Jun 27, 2026

    Se não for possível acessar o site ou se um registro DNS não estiver resolvendo corretamente, use os métodos a seguir para verificar o status do nome de domínio e confirmar a efetividade do registro DNS.

    Comandos dig e nslookup

    As ferramentas de linha de comando mais comuns para consultas DNS incluem o dig, que fornece informações detalhadas de depuração, e o nslookup, disponível por padrão no Windows.

    Importante

    Como interpretar os resultados: se a saída da consulta DNS corresponder às configurações definidas no Alibaba Cloud DNS, o registro DNS foi propagado.

    Caso a saída não corresponda, verifique o TTL. Se o cache local ainda estiver válido, aguarde sua expiração antes de testar novamente.

    Se o cache já tiver expirado e os resultados ainda não coincidirem, consulte Solucionar rapidamente problemas de resolução ineficaz.

    Comando Dig

    1. Consulta básica

    Nota

    Comando: dig <your_domain_name> (Exemplo: dig example.com)

    $ dig example.com
; <<>> DiG 9.11.36-RedHat-9.11.36-16.0.1.al8 <<>> example.com
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 7585
;; flags: qr rd ra; QUERY: 1, ANSWER: 6, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;example.com.                   IN      A

;; ANSWER SECTION:

    2. Consulta por tipo de registro

    Nota

    Comando: dig <your_domain_name> <record_type> (Exemplo: dig example.com NS)

    $ dig example.com NS
; <<>> DiG 9.11.36-RedHat-9.11.36-16.0.1.al8 <<>> example.com NS
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 29146
;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;example.com.                   IN      NS

;; ANSWER SECTION:
example.com.            10      IN      NS      b.iana-servers.net.
example.com.            10      IN      NS      a.iana-servers.net.

;; WHEN: Tue Feb 18 15:03:03 CST 2025
;; MSG SIZE  rcvd: 93

    O exemplo a seguir mostra a saída quando um registro DNS não foi propagado ou não está configurado (Exemplo: dig example.com cname).

    $ dig example.com cname
; <<>> DiG 9.11.36-RedHat-9.11.36-16.0.1.al8 <<>> example.com cname
;; global options: +cmd
;; Got answer:

    3. Consultar um servidor DNS específico

    Nota

    Comando para servidor DNS do Alibaba Cloud: dig <your_domain_name> @ns1.alidns.com (Exemplo: dig example.com @ns1.alidns.com)

    Comando para servidor DNS público: dig <your_domain_name> @223.5.5.5 (Exemplo: dig example.com @223.5.5.5)

    $ dig example.com @ns1.alidns.com

    $ dig +short TXT whoami.ds.akahelp.net
"ns"
"47.xxx.xxx.14"

    6. Encontrar os servidores DNS de um domínio

    Nota

    Comando: dig ns <your_domain_name> (Apenas o nome de domínio raiz é necessário.)

    Comando Nslookup

    1. Verificar os resultados da resolução DNS local.

    Nota

    Comando: nslookup <your_domain_name> (Exemplo: nslookup example.com)

    $ nslookup example.com
Server:         xxx
Address:        xxx#53

Non-authoritative answer:

Name:   example.com
Address: 2600:1406:3a00:21::173e:2e65

    2. Consultar um servidor DNS público

    Nota

    Comando: nslookup <your_domain_name> <public_dns_server> (Exemplo usando um servidor DNS público do Alibaba Cloud: nslookup example.com 223.5.5.5)

    $ nslookup example.com 223.5.5.5
Server:         223.5.5.5
Address:        223.5.5.5#53

Non-authoritative answer:

Address: 2600:1406:bc00:53::b81e:94ce
Name:   example.com
Address: 2600:1408:ec00:36::1736:7f24
Name:   example.com
Address: 2600:1406:3a00:21::173e:2e66
Name:   example.com
Address: 2600:1406:bc00:53::b81e:94c8
Name:   example.com
Address: 2600:1408:ec00:36::1736:7f31

    3. Consulta por tipo de registro

    Nota

    Comando: nslookup -type=<record_type> <your_domain_name> (Exemplo: nslookup -type=NS example.com)

    $ nslookup -type=NS example.com
Server:         100.100.2.136
Address:        100.100.2.136#53

Non-authoritative answer:
example.com     nameserver = b.iana-servers.net.
example.com     nameserver = a.iana-servers.net.

Authoritative answers can be found from:

    4. Consultar um servidor autoritativo específico

    Nota

    Comando: nslookup <your_domain_name> <authoritative_server> (Exemplo: nslookup example.com ns1.alidns.com)

    $ nslookup example.com ns1.alidns.com
Server:         ns1.alidns.com
Address:        120.76.107.55#53
