 You still have the same problem with DNS.
 The DNS servers for KR. are listed as
   ;; AUTHORITY SECTION:
  kr.                     4D IN NS        ns.krnic.net.
  kr.                     4D IN NS        ns.kornet.ne.kr.
  kr.                     4D IN NS        ns.kreonet.re.kr.
  kr.                     4D IN NS        ns.kren.ne.kr.
  kr.                     4D IN NS        ns2.internic.net.
  kr.                     4D IN NS        ns.ripe.net.
 Based on the SOA record, the first of these is the primary
server for KR.
 It is listing your dns servers as
  adfinder.co.kr.         2H IN NS        ns.netcubic.co.kr.
 adfinder.co.kr.         2H IN NS        ns2.netcubic.co.kr.
 adfinder.co.kr.         2H IN NS        ns1.jdns.net.
 adfinder.co.kr.         2H IN NS        ns2.jdns.net.
 However, other DNS servers for KR. disagree about this.
 The current SOA serial number for the KR. zone is
 1999122915
 That looks suspiciously like a date in 1999.  I can&#039;t be sure of
that.  But that, together with the inconsistency of data, suggests
that the KR nameservers are not well managed.
 I don&#039;t know how to solve that problem.  That is a problem you have
to work out how to solve.
