DNS Client vs iCardVerify

DNS Client is a fast, native way to run DNS lookups and debug Domain Name System queries — without the Terminal. Type a domain, pick a record type, and read a clean, human-readable response. It works like dig or nslookup, but with a proper interface. QUERY ANYTHING • All standard DNS record types (A, AAAA, MX, TXT, CNAME, NS, PTR, and more) • Reverse DNS lookups • Recursive queries, with full control over the request ANY RESOLVER, ANY PROTOCOL • DNS over UDP, DNS over HTTPS (DoH), and DNS over TLS (DoT) • Query public resolvers (Google, Cloudflare, Quad9, OpenDNS…) or your own • Compare answers across resolvers to spot propagation differences Built for developers and network engineers who need answers fast.
