## INTRODUCTION



`dnspython` is a DNS toolkit for Python. It supports almost all record types. It

can be used for queries, zone transfers, and dynamic updates. It supports

TSIG-authenticated messages and EDNS0.



`dnspython` provides both high- and low-level access to DNS. The high-level

classes perform queries for data of a given name, type, and class, and return an

answer set. The low-level classes allow direct manipulation of DNS zones,

messages, names, and records.



To see a few of the ways `dnspython` can be used, look in the `examples/`

directory.



`dnspython` is a utility to work with DNS, `/etc/hosts` is thus not used. For

simple forward DNS lookups, it's better to use `socket.getaddrinfo()` or

`socket.gethostbyname()`.



`dnspython` originated at Nominum where it was developed to facilitate the

testing of DNS software.



## ABOUT THIS RELEASE



This is the development version of `dnspython` 2.8.0.

Please read

[What's New](https://dnspython.readthedocs.io/en/latest/whatsnew.html) for

information about the changes in this release.



## INSTALLATION



* Many distributions have dnspython packaged for you, so you should check there

  first.

* To use a wheel downloaded from PyPi, run:



```

    pip install dnspython

```



* To install from the source code, go into the top-level of the source code

  and run:



```

    pip install --upgrade pip build

    python -m build

    pip install dist/*.whl

```



* To install the latest from the main branch, run

`pip install git+https://github.com/rthalley/dnspython.git`



`dnspython`'s default installation does not depend on any modules other than

those in the Python standard library.  To use some features, additional modules

must be installed.  For convenience, `pip` options are defined for the

requirements.



If you want to use DNS-over-HTTPS, run

`pip install dnspython[doh]`.



If you want to use DNSSEC functionality, run

`pip install dnspython[dnssec]`.



If you want to use internationalized domain names (IDNA)

functionality, you must run

`pip install dnspython[idna]`



If you want to use the Trio asynchronous I/O package, run

`pip install dnspython[trio]`.



If you want to use WMI on Windows to determine the active DNS settings

instead of the default registry scanning method, run

`pip install dnspython[wmi]`.



If you want to try the experimental DNS-over-QUIC code, run

`pip install dnspython[doq]`.



Note that you can install any combination of the above, e.g.:

`pip install dnspython[doh,dnssec,idna]`



### Notices



Python 2.x support ended with the release of 1.16.0.  `dnspython` supports Python 3.9

and later.  Future support  is aligned with the lifetime of the Python 3 versions.
