The choice of running the DNS bridge on 127.0.0.53:53 is mostly arbitrary. This

150

is the default.

|
- There is an issue on Nerves and Linux that you may hit if the `:mdns_lite`
|
|
153
|
- application is not running. The Erlang DNS resolver calls `connect` to the IP
|
|
154
|
- address of the DNS server and then calls `connect` again to the next one. The
|
|
155
|
- second `connect` call fails when the first one is a `127.0.0.x` address. See
|
|
156
|
- [Issue 5092](https://github.com/erlang/otp/issues/5092). Setting
|
|
157
|
- `dns_bridge_recursive: true` works around this issue.
|

158

-
|
|
159
|
- Update: Issue 5092 has been fixed in Erlang/OTP 24.1 and you can safely use

160
|
- `dns_bridge_recursive: false` in that version or later.
