Installing

How to use it

In [1]: from domain import Domain

In [2]: domain = Domain("andressa.dev")

In [3]: domain.monitor()
andressa.dev
A record:
['185.199.108.153']
AAAA record:
There's no data for this record type.
CNAME record:
[<DNS name andressadotpy.github.io.>]
MX record:
There's no data for this record type.
NS record:
There's no data for this record type.
TXT record:
There's no data for this record type.

A dangling record is a vulnerability issue. So for your domains that are in your DNS service and are expired/not being used anymore, the monitoring system will print out this message for each record:

A record:

                VULNERABILITY ISSUE:
                This domain doesn't exist anymore.
                Please delete all records pointing for this domain.
