You offer recursion to xx.xx.xx.xx and dig set recursion desired by default so the CNAME is followed. > if query from any other server, > > 192.168.2.1.domain> xx.xx.xx.xx.47127: 58823*- 1/2/2 CNAME[|domain] > > and the answer is > www.example.com. 3600 IN CNAME www.down.example.com. You don't offer recursion to this client so named returns a CNAME and a referral to the child servers. > my question is, > Why the result is different by client? > why first case answers A record also but the second case is cname only? > > > Thanks in advance. > _______________________________________________ > bind-users mailing list > bind-users@lists.isc.org > https://lists.isc.org/mailman/listinfo/bind-users -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: ma...@isc.org _______________________________________________ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
