View Source VintageNet.NameResolver (vintage_net v0.13.3)
This module manages the contents of "/etc/resolv.conf".
This file is used by the C standard library and by Erlang for resolving
domain names. Since both C programs and Erlang can do resolution, debugging
problems in this area can be confusing due to varying behavior based on who's
resolving at the time. See the /etc/erl_inetrc file on the target to review
Erlang's configuration.
This module assumes exclusive ownership on "/etc/resolv.conf", so if any other code in the system tries to modify the file, their changes will be lost on the next update.
It is expected that each network interface provides a configuration. This module will track configurations to network interfaces so that it can reflect which resolvers are around. Resolver order isn't handled.
