plan 9 dns tries to look up unrooted (no ".") names in the local databases.
first success wins.

here's the algorithm from /sys/src/cmd/ndb/dnresolve.c

        /*
         *  hack for systems that don't have resolve search
         *  lists.  Just look up the simple name in the database.
         */
        if(!rooted && strchr(name, '.') == nil){
                rp = nil;
                drp = domainlist(class);
                for(nrp = drp; rp == nil && nrp != nil; nrp = nrp->next){
                        snprint(nname, sizeof nname, "%s.%s", name,
                                nrp->ptr->name);
                        rp = dnresolve(nname, class, type, req, cn, depth+1,
                                recurse, rooted, status);
                        rrfreelist(rrremneg(&rp));
                }
                if(drp != nil)
                        rrfreelist(drp);
                procsetname(procname);
                free(procname);
                return rp;
        }
