 <p class=cont>The list of dicts define where a stub resolver will send queries. Each dict contains
 at least two names: <code>address_type</code> (whose value is a bindata; it is currently either
-"IPv4" or "IPv6") and <code>address_data</code> (whose value is a bindata). It might also contain
+"IPv4" or "IPv6") and <code>address_data</code> (whose value is a bindata).
+For IPv6 link-local addresses, a <code>scope_id</code> name (a bindata) can be provided.  It might also contain
 <code>port</code> to specify which port to use to contact these DNS servers; the default is 53. If
 the stub and a recursive resolver both support TSIG (RFC 2845), the <code>upstream_list</code> entry
 can also contain <code>tsig_algorithm</code> (a bindata) that is the name of the TSIG hash
