[Techs_Maru]

Hi,folks,

Please tell me,
What are the "DNS Traffic tester(Traffic Generator)"  that you are using?

Now, I used,dnsperf & queryperf only.
Do you have recommended the appliance?
(I am thinking about buying of appliances that can real simulate the
Various types of traffic for DNS
 For example, tcp / udp / dnssec / mobile traffic emulation and more....)

Appliance equipment that I know now, avalanche and ixia traffic generator.

best regards.
