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.
dnspython originated at Nominum where it was developed to
facilitate the testing of DNS software. Nominum has generously
allowed it to be opened under a BSD-style licence.
