-//! This resolver supports a fallback mechanism where, should the DNS-over-TLS resolution fail, a
-//! followup resolution will be done using the hosts configured default (e.g. `/etc/resolve.conf` on
-//! linux). This is disabled by default and can be enabled using [`enable_system_fallback`].

+//!
+//! **System Resolver --** This resolver supports an optional fallback mechanism where, should the

+//! default (e.g. `/etc/resolve.conf` on linux).
+//!
+//! This is disabled by default and can be enabled using `enable_system_fallback`.
+//!
+//! **Static Table --**  There is also a second optional fallback mechanism that allows a static map
+//! to be used as a last resort. This can help when DNS encounters errors due to blocked resolvers
+//! or unknown conditions. This is enabled by default, and can be customized if building a new
+//! resolver.
+//!
+//! ## IPv4 / IPv6
+//!
+//! By default the resolver uses only IPv4 nameservers, and is configured to do `A` lookups first,
+//! and only do `AAAA` if no `A` record is available.
+//!
+//! ---
