DoH Batch Resolver

Resolve domain names to IP addresses via DNS-over-HTTPS (DoH).

Usage

python doh_resolver.py [-4] [-6]

• Default: prefers IPv4, falls back to IPv6
• -4 — IPv4 only
• -6 — IPv6 only

Configuration

dns.ini — DoH server URLs, one per line:

https://dns.alidns.com/dns-query  
https://dns.google/dns-query

domain.txt — domain names, one per line:

example.com  
example.org

Output

Results are saved to ip_<timestamp>.txt with domain=ip format. If the file already exists, you will be prompted before overwriting.

Notes

• Only the first resolved IP is used per domain.
• Supports both Google JSON API (?name=&type=) and Alibaba /resolve endpoint formats.
• Multiple DoH servers are supported; the script falls back to the next server on failure.
