Dnscache

Hi ,

 

 

I will be deploying a Viprion as Dnscache for 2 bind servers . These servers are both root and resolver dns for an isp and they host more than 30k domains .

 

I need some clarification on the following points:

 

 

Is there a way to make the F5 not cache specific domains ?

 

 

Whats the best way to delete a specific dns record in the F5 ? i only found one way using tmsh and was wondering if this feature exists in the icontrol .

 

 

The problem im overseeing with cached domains is when some records are changed on the bind it would take this change time to propogate on the F5 i need to have a way to make it changed immediatly on the F5 dnscache.

 

 

Thanks for the assistance

 

M.N
