explicit forward proxy DNS resolver - list servers or use a VS?

For a BigIP http explicit forward proxy, we have a DNS resolver with a list of DNS servers which is referenced in the http explicit profile. This works but I wanted to check for the most appropriate way to implement.

 

Currently, profile http-explicit references a configured DNS resolver with four internal DNS servers. Is it worth using a local DNS_VS and a pool for the four internal DNS servers and using the local DNS_VS IP in the DNS resolver?

 

This is used for WWW clients access to the internet after they have been directed to a particular F5 VS by GTM.

 

Thanks for any help,

 

Derrick

 

  • If would be worth using a VS with a pool if you wished to monitor the availability of the DNS servers in the pool.
