This is a python code for custom DNS Server.

You may face following Errors:-

1. Traceback (most recent call last): File "1DNS.py", line 24, in zonedata = load_zones() File "1DNS.py", line 18, in load_zones data = json.load(zonedata) File "/usr/lib/python3.6/json/init.py", line 299, in load parse_constant=parse_constant, object_pairs_hook=object_pairs_hook, **kw) File "/usr/lib/python3.6/json/init.py", line 354, in loads return _default_decoder.decode(s) File "/usr/lib/python3.6/json/decoder.py", line 339, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "/usr/lib/python3.6/json/decoder.py", line 355, in raw_decode obj, end = self.scan_once(s, idx)

Cause:- The Python json module is strict in its interpretation of JSON. The usual problem is that wherever you are getting your alleged JSON from, is not generating strictly valid JSON. A common mistake is {...}{...} or {...},{...} rather than the valid list-of-dicts [{...},{...}]

Solution :- Check if the zone file is in correct json format. To check the same you can use any online json validator.
