Hi, 

Yes, shouldn't be a problem.

Can I use F5 to do state-full load balancing of Microsoft DNS Servers?

Best regards,
Leon

Hi ,

If you want to Load Balance DNS services, you cannot do that with DNS itself.  There are no clustering or load balancing services built into the DNS service.

There are different design options when considering load balancing.

As your said, you could use some third-party appliances that use the configured load balancing method to select a DNS service. 

The DNS server to which the service is bound then resolves the domain name and returns the IP address as the response. The appliance might also cache DNS responses and use the cached information to respond to future requests for resolution of the same domain name. 

However, if that Load balancer becomes unavailable, no DNS services will be available to your users. 

Here is a similar thread discussed before, you could have a look:
