did not find expected key, when bind to IPv6 Address by modified config.yml file

[geyee]

when change config.yml file some parameters，it run failed.

1. change bindAddress: :53 to bindAddress: [::1]:53, then "Failed to parse config file: yaml: did not find expected node content"
2. debugHTTPAddress: 127.0.0.1:5555 to debugHTTPAddress: [::1]:5555, then "Failed to parse config file: yaml: line 1: did not find expected node content"
3. change address: 119.29.29.29:53 to address: [fe80::1]:53, then "Failed to parse config file: yaml: line 5: did not find expected key"
4. change address: 114.114.114.114:53 to address: [2606:4700:4700::1001]:53，then "Failed to parse config file: yaml: line 15: did not find expected key"

thanks.
