   Make domain verification as easy as verifying an email or phone number▲86

   Hi HN, This is a project [1] I've been working on for a little while and I'm interested in your feedback and point of view. Many of us would have verified a domain name by pasting a string into a DNS TXT record. Some providers ask us to store this DNS TXT record at a domain using a DNS label like "_provider" e.g. _provider.yourdomain.com, and some providers ask that you do it at the zone apex (God help us [2]).

    Using Cloudflare 1.1.1.1 DNS over HTTPS API to bulk search domain TLDs▲11

    I found out Cloudflare has a DNS over HTTPS api via 1.1.1.1 resolver, figured I'd make a small tool out of it, as somene who keeps checking domain names for side projects which I never build, this kinda helps me look for something. It's not fully accurate, because it returns unavailable even for parked pages, which technically are available, but works for me. It just checks for A records via this endpoint https://cloudflare-dns.com/dns-query?name=${domain}&type=A Just make sure to pass this header - "application/dns-json"
