Make your DNS private. DNS Security helps protect your privacy by encrypting DNS queries with DNS over HTTPS (DoH) and DNS over TLS (DoT). Choose a provider, enable your DNS configuration, and manage your settings in one place—without routing your internet traffic through a VPN. WHY ENCRYPT YOUR DNS? HTTPS protects the content exchanged with websites, but traditional DNS lookups may still be unencrypted. These lookups translate domain names into IP addresses and can reveal the domains your device requests. Encrypted DNS helps protect queries between your device and your chosen DNS provider from eavesdropping and tampering. Your provider still handles those queries, so choose one whose privacy practices you trust. EVERYDAY DNS CONTROL • Use DNS over HTTPS or DNS over TLS. • Choose built-in profiles for providers including Cloudflare, Google, and AdGuard. • Enable or disable your DNS configuration from the app. • Choose whether DNS settings apply on Wi-Fi, cellular, or both. • Check DNS protocol and provider details in the Status tab. DNS SECURITY OR DNS SECURITY PRO? DNS Security includes the everyday DNS controls above at no cost. It offers an optional Pro in-app purchase for the advanced features below. DNS Security Pro is the paid edition. It includes the same everyday DNS controls plus these advanced features from the start: PRO FEATURES (IN APP PURCHASE) • Create custom DoH and DoT profiles. • Download updates to built-in DNS profiles. • Enable or disable DNS for specific Wi-Fi SSIDs. • Switch profiles with Shortcuts and URL schemes. The difference is advanced control: both editions support encrypted DNS. You can unlock the Pro tools inside DNS Security or choose DNS Security Pro with those tools already included. DESIGNED AROUND PRIVACY DNS Security manages your device's DNS configuration and does not collect personal information. DNS requests are handled by your selected provider under that provider's privacy policy. Encrypted DNS protects DNS queries; it does not make all browsing anonymous. Blocking malicious domains depends on the provider and profile you choose. AUTOMATE YOUR DNS With Pro, use Shortcuts or a compatible app to open a switch URL and select a DNS profile with your preferred network settings. Example: select google-DOH for Wi-Fi, with cellular disabled: dnsapp://switch?config=google-DOH&enableOnWifi=true&enableOnCellular=false Use the scheme for your installed app: • DNS Security Pro: dnssecuritypro:// • DNS Security: dnssecurity:// • Shared scheme: dnsapp:// Replace dnsapp in the example with your app's scheme. The requested profile must already exist in the app. Initial activation may require selecting DNS Security in iOS Settings. Choose your DNS. Control your settings. Add privacy to every lookup that uses your encrypted DNS configuration.

DNS Mail Info

Read full description

This app is used to troubleshoot domain based email problems. It allows you to add any number of domains (limited by the hardware you are running it on) to test your DNS resolvers. Specifically, for BIMI, DMARC, NS, MX, SPF, and WhoIs records. The data is stored locally after a DNS refresh request has been performed. You can refresh one domain, or all of them at the same time. Once the domain data has been gathered, you can save a snapshot (or more). If a snapshot is different than the current information, the snapshot will highlight so you can review the changes. If you have a DMARC reporter configured, quick reports can also be made. Currently supported DMARC providers are Postmarkapp.com and Demarkreport.com. With access to other DMARC reporter's API, I can add others. Features: - Look up domain records using the default name servers, or from a list of public nameservers. - Domains can have a spefified default name server. - Domain look ups can be saved, and are tested for differences with last domain refresh - WhoIs information is also saved and is tested for differences domain refresh. - Many on-line DNS tools are simple click from within the app. - DNS records collected are: BIMI, DMARC, NS, MX, and SPF. - Whois record is collected - A set of example domains can be added as a quick start. - Mail can be sent to the domain MailTo using the host mail client - Refresh a single domain's DNS records or all of your configured domain's DNS records Roadmap: - Domain PDF reports can be email'ed or printed - Mail can be sent to a specific MX server.
