Hi Duleep,

After starting BIND, can you examine its log entries? It should print 
all the addresses it is binding to, eg:

09-Jul-2020 13:50:57.674 listening on IPv4 interface lo0,
09-Jul-2020 13:50:57.676 IPv6 socket API is incomplete; explicitly 
binding to each IPv6 address separately
09-Jul-2020 13:50:57.676 listening on IPv6 interface lo0, ::1#53
09-Jul-2020 13:50:57.677 listening on IPv6 interface lo0, fe80::1%1#53
09-Jul-2020 13:50:57.678 listening on IPv6 interface en0, 
09-Jul-2020 13:50:57.679 listening on IPv4 interface en0,
09-Jul-2020 13:50:57.680 listening on IPv6 interface en0, 
09-Jul-2020 13:50:57.681 listening on IPv6 interface en0,
