### The problem

Roundrobin/load balancing requests for a domain to multiple ip addresses
for i.e:

we could set multi ip via rewrite rules for example.com, everytime the client request example.com, one of the ip addresses would go to client ( it should support the below feature too - something like roundrobing geodns system ! )

### Proposed solution

- Randomize ip return based on a roundrobin algorithm
- Advanced one, check ping availability of these ip addresses, only randomize the available ones not all ip addresses in the pool
