View JDK DNS cache

[Adrian Lewis]

Hi, 

I am making some comparisons over IPv4 and IPv6 response times over a high load. I am creating an IPv4 baseline and disabled IPv6 in the JDK and in the kernel networking. Is there any way to view the IP addresses in the JDK DNS cache during a simulation run? 

Many Thanks

Aidy

This looks similar to what you're trying to do (Java example):

I had to change one line before it would compile and run:

Field af = cacheEntryKlass.getDeclaredField("address");

to:

Field af = cacheEntryKlass.getDeclaredField("addresses");

Does that help at all?

Cheers,

Barry
