zone2json

This utility converts the records of a DNS (BIND) zone file to JSON/XML/YAML objects.

Usage

Here is a sample of DNS records from some zone file:

almroot@x:~(master)$ cat /tmp/zone-se | head -n 50 | tail -n 10

Now the same data is converted to JSON to be used in conjunction with jq or similar tooling:
