Netbox DNS exporter

This script will generate forward and reverse DNS zones files based on Netbox data, according to the supplied configuration file.

The following records will be generated:

• An entry per device using its primary IP. If both IPv4 and IPv6 primary addresses are configured it will generate both A and AAAA records (as well as the corresponding PTR records).
• An entry per IP/IPv6 configured on a device interface (except those flagged as primary addresses), replacing all non letter/number characters with hyphens (-). For instance: interface xe-0/1/0.42 on my-router.example.com will becomre xe-0-1-0-42.my-router.example.com.

All records can be overriden using Netbox's DNS Name field.

All devices' names must be fully qualified for forward DNS zones to be generated.

This script will also try to retrieve from Netbox a config context named after the zone's name for additional records to be included in the generated zone file. If it exists, the config context must adhere to the following format:

{
    "records": [
        {
            "data": "\"v=spf1 -all\"",
            "rr": "@",
            "type": "TXT"
        },
        {
            "data": "\"v=DMARC1;p=reject;sp=reject;adkim=s;aspf=s\"",
            "rr": "_dmarc",
            "type": "TXT"
        },
        {
            "data": "0 .",
            "rr": "@",
            "type": "MX"
        }
    ]
}
