    • dig命令

    1 . 最常用的查询命令

    说明

    命令：dig 您的域名（示例：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:

    example.com. 10 IN A 96.7.128.175

    example.com. 10 IN A 96.7.128.198

    example.com. 10 IN A 23.192.228.84

    example.com. 10 IN A 23.215.0.136

    example.com. 10 IN A 23.192.228.80

    example.com. 10 IN A 23.215.0.138

    ;; Query time: 0 msec

    ;; WHEN: Tue Feb 18 13:31:55 CST 2025

    ;; MSG SIZE rcvd: 125

    2 . 根据记录类型进行查询，比如MX，CNAME，NS，PTR等，只需将类型加在命令后面即可。

    说明

    命令：dig 您的域名 记录类型（示例：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.

    ;; Query time: 0 msec

    ;; WHEN: Tue Feb 18 15:03:03 CST 2025

    ;; MSG SIZE rcvd: 93

    解析未生效、或者未设置解析记录场景的示例（示例：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:

    ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 39890

    ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0

    ;; QUESTION SECTION:

    ;example.com. IN CNAME

    ;; AUTHORITY SECTION:

    example.com. 5 IN SOA ns.icann.org. noc.dns.icann.org. 2025011545 7200 3600 1209600 3600

    ;; Query time: 143 msec

    ;; WHEN: Tue Feb 18 13:50:18 CST 2025

    ;; MSG SIZE rcvd: 94

    3 . 指定域名DNS服务器测试解析是否生效的命令，以下以指定云解析DNS服务器和公共DNS服务器作为查询解析是否生效的示例演示。

    说明

    云解析DNS服务器命令：dig 您的域名 @ns1.alidns.com （示例：dig example.com @ns1.alidns.com ）

    公共DNS服务器命令：dig 您的域名 @223.5.5.5（示例：dig example.com @223.5.5.5 ）

    $ dig example.com @ns1.alidns.com

    ; <<>> DiG 9.11.36-RedHat-9.11.36-16.0.1.al8 <<>> example.com @ns1.alidns.com

    ;; global options: +cmd

    ;; Got answer:

    ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 32895

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

    ;; WARNING: recursion requested but not available

    ;; OPT PSEUDOSECTION:

    ; EDNS: version: 0, flags:; udp: 4096

    ;; QUESTION SECTION:

    ;example.com. IN A

    ;; AUTHORITY SECTION:

    example.com. 600 IN SOA ns1.alidns.com. hostmaster.hichina.com. 2025021713 3600 1200 86400 600

    ;; Query time: 5 msec

    ;; WHEN: Tue Feb 18 15:22:09 CST 2025

    ;; MSG SIZE rcvd: 112

    $ dig example.com @223.5.5.5

    ; <<>> DiG 9.11.36-RedHat-9.11.36-16.0.1.al8 <<>> example.com @223.5.5.5

    ;; global options: +cmd

    ;; Got answer:

    ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 42292

    ;; flags: qr rd ra; QUERY: 1, ANSWER: 6, AUTHORITY: 0, ADDITIONAL: 1

    ;; OPT PSEUDOSECTION:

    ; EDNS: version: 0, flags:; udp: 1408

    ;; QUESTION SECTION:

    ;example.com. IN A

    ;; ANSWER SECTION:

    example.com. 67 IN A 96.7.128.175

    example.com. 67 IN A 96.7.128.198

    example.com. 67 IN A 23.215.0.136

    example.com. 67 IN A 23.215.0.138

    example.com. 67 IN A 23.192.228.84

    example.com. 67 IN A 23.192.228.80

    ;; Query time: 1 msec

    ;; SERVER: 223.5.5.5#53(223.5.5.5)

    ;; WHEN: Tue Feb 18 15:16:32 CST 2025

    ;; MSG SIZE rcvd: 136

    4 . 使用dig +trace参数，使用这个参数之后将显示从根域逐级查询的过程，trace查询可以看到根域、 顶级域、以及一级域名的权威服务器的地址，及其各自的返回结果，这样对于追踪DNS解析中的问题有很大的帮助。

    说明

    命令：dig <您的域名> +trace（示例：dig example.com +trace）

    $ dig example.com +trace

    ; <<>> DiG 9.11.36-RedHat-9.11.36-16.0.1.al8 <<>> example.com +trace

    ;; global options: +cmd

    . 515049 IN NS j.root-servers.net.

    . 515049 IN NS k.root-servers.net.

    . 515049 IN NS a.root-servers.net.

    . 515049 IN NS b.root-servers.net.

    . 515049 IN NS c.root-servers.net.

    . 515049 IN NS d.root-servers.net.

    . 515049 IN NS e.root-servers.net.

    . 515049 IN NS f.root-servers.net.

    . 515049 IN NS g.root-servers.net.

    . 515049 IN NS h.root-servers.net.

    . 515049 IN NS i.root-servers.net.

    . 515049 IN NS l.root-servers.net.

    . 515049 IN NS m.root-servers.net.

    ;; Received 819 bytes from 100.100.2.136#53(100.100.2.136) in 1 ms

    5 . 获取 DNS 出口 IP，通过查询特殊域名返回客户端出口 IP（即本地 DNS 服务器对外的公网 IP），确认 NAT 或代理后的真实请求源地址（影响 CDN 调度）。

    说明

    命令：dig +short TXT whoami.ds.akahelp.net

    $ dig +short TXT whoami.ds.akahelp.net

    "ns"

    "47.xxx.xxx.14"

    6 . 查询域名使用的域名DNS服务器。

    说明

    命令：dig ns 您的域名（这里输入主域名即可）

    $ dig ns example.com

    ; <<>> DiG 9.11.36-RedHat-9.11.36-16.0.1.al8 <<>> ns example.com

    ;; global options: +cmd

    ;; Got answer:

    ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 58283

    ;; 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 a.iana-servers.net.

    example.com. 10 IN NS b.iana-servers.net.

    ;; Query time: 5 msec

    ;; SERVER:

    ;; WHEN: Tue Feb 18 16:09:33 CST 2025

    ;; MSG SIZE rcvd: 93

    7 . 可通过指定客户机IP，查询权威DNS返回的解析地址，来判断智能解析调度的精准度。

    说明

    命令：dig @权威DNS服务器 域名 +subnet=指定客户机IP（示例：dig @ns1.alidns.com example.com +subnet=10.10.10.10）

    $ dig @ns1.alidns.com example.com +subnet=10.10.10.10

    ; <<>> DiG 9.11.36-RedHat-9.11.36-16.0.1.al8 <<>> @ns1.alidns.com example.com +subnet=10.10.10.10

    ; (9 servers found)

    ;; global options: +cmd

    ;; Got answer:

    ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 60880

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

    ;; WARNING: recursion requested but not available

    ;; OPT PSEUDOSECTION:
