About DNS over HTTPS (DoH)
This tool performs DNS lookups using DNS over HTTPS (DoH), which encrypts DNS queries to protect your privacy. Traditional DNS queries are sent in plain text, allowing ISPs and network operators to see which domains you're querying. DoH wraps these queries in HTTPS, making them indistinguishable from regular web traffic.
