During this second part of the complete series “The Complete F5 Bootcamp (LTM,ASM,DNS)” , we tackled the main needed configurations related to the most important features of f5 bigip DNS module .
Section one is a quick introduction to DNS protocol and role of DNS module inside our network , also we have tackled the main internal functions of f5 bigip DNS module ( DNS Acceleration , Intelligent DNS & DNSSEC ) .
In section two , we have discussed the main technologies could be used for improving the performance of resolving of existed DNS servers in our internal environment by using three main methods :-
– DNS Acceleration .
– DNS Cache .
– Load Balancing .
In the next section , we have covered all the needed objects inside GSLB or Intelligent DNS and how to configure them on our bigip DNS module :-
– Servers / Virtual Servers .
– Datacenters .
– Pools .
– Wide IPs .
Section four is an application on the load balancing methods that we can use on the intelligent DNS to make the best answer DNS response to the client like ( Round trip time , Number of hops , Topology , Least Connections , others )
Finally we’ll see some different topics could be used with bigip DNS module like ( DNSSEC , iRules ) and how to use both on our bigip DNS module .
