Description

What problem are you trying to solve?

Some block lists use 127.0.0.1 instead of 0.0.0.0 for their entries, which is mildly annoying to see my localhost on blocked domains.

For example:

127.0.0.1 cdn.tinypass.com
AdAway Default Blocklist

0.0.0.0 cdn.tinypass.com
Steven Black's List

Furthermore, if different block lists use different IPs, it duplicates both in the dns lookup:

$ nslookup cdn.tinypass.com
Non-authoritative answer:
Name:    cdn.tinypass.com
Addresses:  ::
          127.0.0.1
          0.0.0.0

Proposed solution

Replace all blocked host ips to 0.0.0.0.

I can't think of any valid reason as to why the original ip provided by the block list is used. Does adguard have an allow list of which ips are allowed?

Alternatives considered
