toggle option to turn off 'Custom IP network Dispatcher' #152

Closed april4 closed 5 years ago

april4 commented 5 years ago

provide option to turn off 'Custom IP network Dispatcher', or auto turn off(i.e. Like 'WhenPrimaryDNSAnswerNoneUse', only use alternative DNS when response of PrimaryDNS exists and there is no ANSWER SECTION in it.) this when: 

  "IPNetworkFile": {
    "Primary": "",
    "Alternative": ""
  },

'IPNetworkFile' path is empty.
Otherwise it will always use alternative DNS, when 'IPNetworkFile' path is empty, twice time then only use primary DNS.
If i fill 'ip_network_primary_sample' with all North America network CIDR(estimate 75k line), this will cause the query time more slower(7~15s).

Try 0.0.0.0/0 ?

Try 0.0.0.0/0 ?

Current workaround is add those: 

0.0.0.0/1  
255.255.255.255/1

to 'ip_network_primary_sample'
