The Network Tools
38+ free DNS, email and network tools. A calmer MXToolbox alternative.
The Network Tools brings 38+ free DNS, email, SSL and domain tools into one browser-based workspace. It is for developers, system administrators and people managing websites or email who want related checks together. You can run the public checks without signing up.
DNS lookup shows records such as A, AAAA, MX and TXT. Email tools help inspect SPF, DKIM and DMARC records, including the published DMARC policy. WHOIS and IP lookups provide domain registration and network information. The SSL checker shows certificate details such as issuer, expiry and validity. Blacklist checks report whether an address is listed on the specific DNS blocklists tested, rather than claiming that a clean result guarantees delivery everywhere.
Use it to investigate a domain change, review email authentication or check a certificate before it expires. A calmer MXToolbox alternative, with free checks separate from optional account-based monitoring and alerts.
