It is possible to not use the default DNS configuration when resolving a specific host such as specifying a particular DNS server, different number of request retry and so on. When calling DNSc_GetHost() it is possible to specify a request configuration in the parameter p_cfg.
The following structure contains the possible request configuration:
typedef struct DNSc_req_cfg {
DNSc_ADDR_OBJ *ServerAddrPtr;
NET_PORT_NBR ServerPort;
CPU_INT16U TaskDly_ms;
CPU_INT16U ReqTimeout_ms;
CPU_INT08U ReqRetry;
} DNSc_REQ_CFG;
