Front Server-Based DNS Resolution for OneIP Table

Custom DNS server settings configured for the OneIP Table are currently applied and executed only from the NetBrain core server, which in some customer environments does not have network connectivity to the designated DNS server. This limitation prevents hostname resolution from completing successfully even though a Front Server in the same environment does have the required connectivity. This enhancement proposes allowing the custom DNS server configuration and associated resolution calls for the OneIP Table to be executed from the Front Server instead of the core server. Customers whose DNS infrastructure is only reachable from the Front Server would gain accurate hostname resolution for unknown entries without requiring additional network changes or workarounds.
