dnszone 3.1.1

Fork of Easy Zone - DNS Zone abstraction module

dnszone

Overview

This package is forked from Easyzone, created by Chris Miles. I have forked it to include bugfixes for installation and also to update the package for compatibility with Python 3.

DNSZone is a package to manage the common record types of a zone file, including SOA records. This module sits on top of the dnspython package and provides a higher level abstraction for common zone file manipulation use cases.

Main features:

• A high-level abstraction on top of dnspython.
• Load a zone file into objects.
• Modify/add/delete zone/record objects.
• Save back to zone file.
• Auto-update serial (if necessary).
