Subject:  Some questiones about DNS Redirection


  Hello
  I am an engineer of an ISP.
  I had read the Alteon’s white paper (Optimizing ISP Networks and Services with
  DNS Redirection),
  and I have some questions. (My company uses Alteon’s switch ACE 180)

  1. Some people test DNS redirection. They said that redirected DNS query from
  a client resolver
  is success(Case 1), but query through a local DNS Server is fail(Case 2). What
  is the difference between two cases?
   Case 1: Client PC  --- L4 Switch (Alteon 180) ---- DNS Server      = success
   Case  2:  Client PC  --- local DNS Server --- L4 Switch (Alteon 180) ---- DNS
  Server  = fail
    Are there any differences between query packet format or flags ?

  2. Are there any case studies about DNS Redirection?

  Looking for your kind reply .
