网站 IP

Look up the IP address and DNS records of any website or domain name. Enter a domain (e.g. google.com) and we'll query Google Public DNS to retrieve all available records.

什么是 DNS？

The 域名系统（DNS） is the phonebook of the Internet. When you type a domain name like google.com into your browser, DNS translates it into an IP address like 142.250.80.46 that computers use to identify each other on the network.

常见 DNS 记录类型

• A 记录 — Maps a domain to an IPv4 address (e.g. 142.250.80.46)
• AAAA 记录 — Maps a domain to an IPv6 address (e.g. 2607:f8b0:4004::200e)
• CNAME 记录 — Alias of one domain to another (e.g. www.example.com → example.com)
• MX 记录 — Specifies mail servers responsible for receiving email for the domain
• NS 记录 — Lists the authoritative name servers for the domain
• TXT 记录 — Stores text data, commonly used for SPF, DKIM, and domain verification
• SOA 记录 — Start of Authority, contains administrative information about the zone

这个工具如何工作？

This tool queries Google 公共 DNS (dns.google) over HTTPS for each record type. Your domain name is never stored or logged — the lookup happens directly between your browser and Google's DNS servers.

为什么需要 DNS 查询？

• 故障排除 — Check if your domain's DNS records are configured correctly
• 邮件问题 — Verify MX, SPF, and DKIM records for email delivery
• 安全 — Review TXT records for domain verification and authentication
• 迁移 — Confirm DNS changes have propagated after switching hosting providers
