+
+A list of domain suffixes for which A/AAAA queries are answered from the
+[neighbor resolver](/configuration/shared/neighbor/) instead of the upstream.
+
+Each entry must start with `.`. Only queries whose host part (the portion
+before the suffix) contains no dots are matched; `.` matches any
+single-label name such as `nas`.
+
+Example: `[".", ".lan"]`.

 ### Dial Fields
