About DoH (DNS over HTTPS)
DoH performs DNS queries over HTTPS, improving security and privacy compared to traditional DNS.
- Security: Encrypted HTTPS reduces DNS hijacking and sniffing risks.
- Privacy: DNS queries are encrypted to protect user privacy.
- Accuracy: Avoids DNS response tampering by intermediaries.
- Compatibility: Uses standard HTTP/HTTPS ports and is less likely to be blocked.
About TTL
TTL (Time To Live) is the cache lifetime of a DNS record, measured in seconds:
- Lower TTL updates faster but increases DNS server load.
- Higher TTL caches longer and speeds up lookups.
- Common TTLs: 300s (5 minutes), 600s (10 minutes), 3600s (1 hour).
Examples
A record lookup:
Enter a domain like "baidu.com" and select A to get its IPv4 address.
CNAME lookup:
Enter a domain like "www.github.com" and select CNAME to see the alias target.
TXT lookup:
Check text verification records such as SPF or DKIM.
NS lookup:
View authoritative DNS server information for a domain.
Notes
- Only standard public domains are supported.
- Results may vary slightly across DNS servers.
- If no records are returned, try another server or record type.
