About DNS Records & DNS-over-HTTPS (DoH)
The Domain Name System (DNS) maps human-readable domain names (like google.com) to machine-readable IP addresses. DNS-over-HTTPS (DoH) is a protocol for performing remote Domain Name System resolution via the HTTPS protocol. It increases user privacy and security by preventing eavesdropping and manipulation of DNS data by man-in-the-middle attacks.
How to use the DNS Lookup Tool
1. Enter Domain: Input the domain name you want to query (e.g., github.com).
2. Choose Record Type: Select the DNS record type you want to find (A, CNAME, MX, TXT, etc.).
3. Select DoH Provider: Choose between Cloudflare and Google secure resolvers.
4. Inspect Output: View TTL metrics, record values, and expand the raw JSON response payload at the bottom for advanced usage.
DNS Record Types Explained
- A / AAAA: Maps a domain to IPv4 (A) or IPv6 (AAAA) addresses.
- CNAME: Canonical Name record. Points a domain alias to another domain name.
- MX: Mail Exchanger record. Specifies the mail servers responsible for receiving emails for the domain.
- TXT: Text records. Used for verification (like Google Site Verification, SPF, and DKIM).
Privacy first: Queries are sent directly from your browser to Cloudflare or Google secure DoH servers. Anyuan does not log your domains or IP records.
