步驟一：哪個系統？
Google 提供多種 DNS 相關產品和系統。請務必在適當位置回報問題，以便與能協助處理受影響系統的人員聯絡。
討論群組
您可以發布貼文並訂閱下列群組，以便取得 Google 公用 DNS 的最新消息，以及討論 Google 公用 DNS 和 DNS 基礎架構的設計和實作方式：
public-dns-discuss
這個論壇旨在介紹及討論可改善網際網路 DNS 基礎架構的新想法、產品和計畫。您也可以透過這項工具，針對 Google 公用 DNS 功能提供意見回饋。這個論壇會經過審核，您的訊息只有在獲得核准後才會顯示。
請勿使用這份表單回報安全性相關問題，請按照下方說明，在 Issue Tracker 中回報這類問題。
public-dns-announce
這是一個唯讀清單，您可以在此取得 Google 公用 DNS 的新版本、版本發布和功能資訊，以及服務目前的狀態。
報表問題
如果您在使用 Google 公共 DNS 時遇到問題，請先執行診斷測試。如果問題是 Google 公用 DNS 無法解析特定網域，請使用 intoDNS 和 DNSViz 檢查名稱伺服器或 DNSSEC 問題。這些問題是大多數回報問題的原因，而且通常可以自行解決。
如果無法解決問題，並想要回報問題，可以使用以下兩種方法：
無論是哪種情況，請在回報中提供下列資訊：
- 遇到問題的日期和時間
- 你的位置
- 發現問題的平台 (例如 Mac、Windows、路由器等)
- 發生問題的主機名稱
- 問題是否持續發生或偶爾出現
- 工具的名稱伺服器診斷報表頁面連結
- 您在診斷測試中執行的指令輸出內容
問題追蹤工具詳細資料
Issue Tracker 中包含兩個公用 DNS 元件。這些範本可用於解決常見問題，協助您提供正確資訊，以利我們進行調查。
在上述兩個元件中提交問題時，系統會為問題分配追蹤號碼，並指派 Google 公用 DNS 工程師處理。您可以查看問題的更新記錄和狀態。如需 Issue Tracker 的其他說明，請參閱相關說明文件。

Be sure to report your\nproblems in the appropriate place, to reach someone who can help with the\naffected system.\n\n- If the problem relates to resolving `www.google.com`, `www.youtube.com`, or other Google properties in general, including geo-targeting:\n - If you operate an ISP use [Google's ISP Portal](https://isp.google.com/) to report the issue. ([Request access](https://isp.google.com/portalaccess) first, if necessary.) Or, read the [peering FAQ](https://peering.google.com/#/learn-more/faq) for more.\n - If you are a customer of an ISP please contact them, and ask them to reach out to Google as per the above bullet point.\n- If you used Google Domains' default settings to host your authoritative DNS (and others are having trouble with your domain), reach out to Squarespace support. [Google domains was acquired by Squarespace on September 7th, 2023](https://support.squarespace.com/hc/en-us/articles/17131164996365-About-the-Google-Domains-migration-to-Squarespace).\n- If you are observing a problem that happens with Google Public DNS but not other resolvers, continue reading this page.\n\nDiscussion groups\n-----------------\n\nYou can post and subscribe to the following groups to get updates on Google\nPublic DNS, and to discuss the design and implementation of Google Public DNS\nand DNS infrastructure in general:\n\n- [public-dns-discuss](//groups.google.com/group/public-dns-discuss)\n\n This is a forum for presenting and discussing new ideas, products, and\n initiatives that improve DNS infrastructure across the Internet.\n You can also use it to provide feedback on Google Public DNS features.\n This forum is moderated; your message only appears after it is approved.\n ***Do not use this to report security-related issues***;\n report them on the Issue Tracker as noted below.\n- [public-dns-announce](//groups.google.com/group/public-dns-announce)\n\n This is a read-only list where you can get information on new versions,\n releases, and features of Google Public DNS, as well as current status of\n the service.\n\nReporting issues\n----------------\n\nIf you encounter a problem with Google Public DNS, first please run the\n[diagnostic tests](/speed/public-dns/docs/troubleshooting).\nIf the issue is that a specific domain cannot be resolved by Google Public DNS,\ncheck it with [intoDNS](http://intodns.com/) and [DNSViz](http://dnsviz.net/) for name server or DNSSEC problems.\nThese cause most reported issues, and you can often solve them yourself.\n\nIf you are unable to resolve the problem, and would like to report an issue,\nyou have two options:\n\n- Post to [public-dns-discuss](//groups.google.com/group/public-dns-discuss).\n This shares your report publicly, and allows you to get feedback from other\n Google Public DNS users.\n If your report is security-related, ***do not post it here***;\n please use the Issue Tracker as noted below.\n\n- Open an issue in the [Issue Tracker](//issuetracker.google.com/bookmark-groups/77752).\n Please use this option to report any security-related issues,\n such as Google Public DNS returning results that should fail DNSSEC validation.\n See the [details](#issue_tracker) section below.\n\nIn either case, please include the following information in your report:\n\n- The date and time you encountered the problem\n- Your location\n- The platform on which you are noticing the problem (e.g. Mac, Windows, router, etc.)\n- The hostname(s) for which you are having a problem\n- Whether the problem is continuous or intermittent\n- The links to the tools' name server diagnosis report page\n- The output of the commands you ran in the [diagnostic tests](/speed/public-dns/docs/troubleshooting)\n\nDetails on Issue Tracker\n------------------------\n\nThere are two components for Public DNS in the Issue Tracker. They have\ntemplates for common problems to help you provide the right information for us\nto investigate.\n\n- [Public Trackers \\\u003e Public DNS](https://issuetracker.google.com/issues/new?component=191657)\n For issues with no confidential information. Available templates:\n\n - [Cache Flush](https://issuetracker.google.com/issues/new?component=191657&template=1021881): Problems flushing domain names.\n - [DNS-over-HTTPS](https://issuetracker.google.com/issues/new?component=191657&template=1189745)\n - [DNS-over-TLS](https://issuetracker.google.com/issues/new?component=191657&template=1189719)\n - [Domain Problems](https://issuetracker.google.com/issues/new?component=191657&template=1211345): Problems with a domain that are specific to Google Public DNS.\n - [Other](https://issuetracker.google.com/issues/new?component=191657&template=847301)\n- [Public Trackers \\\u003e Public DNS \\\u003e Restricted](https://issuetracker.google.com/issues/new?component=191885)\n For issues that may have confidential information related to an operator or\n domain. Also report security vulnerabilities here. This keeps your report\n private to yourself and Google Public DNS engineers. Available templates:\n\n - [Domain Problems](https://issuetracker.google.com/issues/new?component=191885&template=1213505): Problems with a domain that are specific to Google Public DNS.\n - [Rate Limit Request](https://issuetracker.google.com/issues/new?component=191885&template=1024641): Requests to increase rate limits for ISPs and network operators.\n - [Recursive Denial of Service](https://issuetracker.google.com/issues/new?component=191885&template=1024952): Authoritative nameservers receiving high-volume of DNS queries from Google Public DNS.\n - [Reflection Denial of Service](https://issuetracker.google.com/issues/new?component=191885&template=1024950): Receiving large volume of DNS responses from Google Public DNS (8.8.8.8).\n - [Vulnerability Report](https://issuetracker.google.com/issues/new?component=191885&template=1023681)\n - [Other](https://issuetracker.google.com/issues/new?component=191885&template=847501)\n\nFiling an issue in either of the two components gives the issue a tracking\nnumber and a Google Public DNS engineer will be assigned to handle it. You can\nview the issue's history and status as it is updated. For more help with the\nIssue Tracker itself please see its\n[documentation](https://developers.google.com/issue-tracker/)."]]
