DNS Robot
DNS Robot — Free DNS propagation checker plus 50+ DNS, email and network tools, in 12 languages and with no sign-up.
About DNS Robot
DNS Robot is a free toolkit for checking and fixing DNS, email and network problems. Its DNS Propagation Checker queries 30+ DNS servers worldwide and shows on a live map where a change has spread. Alongside it are 50+ tools: DNS lookup for every record type, WHOIS/RDAP lookup, SSL checker, SPF, DKIM and DMARC checkers, email header analyzer, IP blacklist checker, port checker, subdomain finder, hosting checker, ping and traceroute. Every tool is free, works without sign-up and is available in 12 languages, and developers can use the free public DNS API.
- Who it is for
- Web developers, sysadmins, site owners and email marketers who need to check DNS, email and network settings quickly.
- Problem it solves
- DNS and email problems are hard to see. After changing nameservers or records, people can't tell whether the change has spread, whether their SPF, DKIM and DMARC records are valid, or why a website or email is failing. The tools that answer these questions are scattered across different sites, often need an account, and are usually English-only.
- The solution
- DNS Robot puts 50+ free diagnostic tools in one place. Enter a domain or IP and get the answer right away: where a DNS change has propagated worldwide, which records exist, whether email authentication passes, who hosts a site, whether an IP is blacklisted and whether a port is open. Results link to plain-language guides that explain how to fix what is wrong.
- What makes it unique
- Everything is free with no sign-up, the propagation checker shows live results on a world map from 30+ DNS servers, and every tool and guide is available in 12 languages, which most DNS tools don't offer. Developers also get a free public DNS API.
