Netdisco error on startup

Configuration
1

I am getting this error from discovering netdisco:

 File "/usr/local/lib/python3.7/site-packages/netdisco/discoverables/__init__.py", line 125, in info_from_entry
    ATTR_HOST: str(ipaddress.ip_address(entry.address)),
  File "/usr/local/lib/python3.7/ipaddress.py", line 54, in ip_address
    address)
ValueError: None does not appear to be an IPv4 or IPv6 address

At HA 0.107.7
Not aware of what netdisco is for and I have not seen any other operational errors.

NETwork DISCOvery.

It has been depreciated in favour of zeroconf.

So why is “discovery:” in configuration.yaml looking for it?
I do not explicitly reference netdisco in my configuration files.
(Same error message in HA 0.108.0)

After a few restarts the error message at startup disappeared. Now a netdisco related error appeared this morning. It appears that it was looking for apple_tv which was powered OFF. To avoid this error
I ignore apple_tv in configuration.yaml.

discovery:
  ignore:
    - apple_tv
    - igd

Two questions:

  1. Why do I still see netdisco if depreciated?
  2. Why does the ignore feature not work?

  1. Depreciated does not mean unused. Eventually it will be removed.
  2. IDK. Open an issue on github.
