Decision gist · record as of 2026-08-14
Yes. dnspython is production-stable (Development Status 5), actively maintained with recent commits, has no required dependencies, and ranks in the top 1000 PyPI packages by downloads. The ISC license is permissive. Install it if you need DNS queries, zone operations, or DNSSEC validation in Python; avoid it only if you need simple hostname resolution.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later.
- Optional features (DNSSEC, DNS-over-HTTPS, IDNA, Trio, WMI, DNS-over-QUIC) require additional dependencies installed via extras.
- Low friction: pure-Python wheel with no runtime dependencies by default.

Verify before relying
pip install dnspython
Import the package and use high-level query classes to resolve DNS records, or low-level classes to manipulate DNS messages and zones directly.- Whether the package's DNSSEC, DNS-over-HTTPS, and DNS-over-QUIC features are production-ready or experimental.

- Specific code examples demonstrating high-level and low-level API usage.
What it is and what it does
dnspython is a comprehensive DNS toolkit for Python that provides both high-level query interfaces and low-level access to DNS zones, messages, names, and records. It supports nearly all DNS record types and can perform queries, zone transfers, and dynamic updates, with optional support for TSIG authentication, EDNS0, DNSSEC, DNS-over-HTTPS, DNS-over-QUIC, and internationalized domain names. The package has no required runtime dependencies beyond the Python standard library, making it lightweight to install and use.
The library is designed for DNS software testing and general-purpose DNS operations. It bypasses system DNS configuration and performs direct DNS queries, making it suitable for applications that need explicit DNS control. High-level classes simplify common tasks like looking up records by name, type, and class, while low-level classes allow direct manipulation of DNS structures for advanced use cases.
Use it for
- Perform DNS lookups and queries for specific record types in Python applications.
- Implement DNS zone transfers and dynamic DNS updates for DNS management tools.
- Validate DNSSEC signatures and perform secure DNS operations when dnssec extra is installed.
- Build DNS testing and validation tools that need direct control over DNS messages and records.
- Query DNS over HTTPS or QUIC for privacy-focused DNS operations with optional extras.
- Resolve internationalized domain names when idna extra is installed.
