bookkeeper should handle ipv6 ip address

[sijie]

Problem

Currently bookie doesn't handle ipv6 ip address very well. when a bookie advertises itself, it might put an ipv6 address with bookie port, the ipAddress:port pair will be recorded in formats like xxxx:a06:ttttf1:fef:0:yyyy:3181, which will fail the client parsing. we need to make sure when bookie advertising ipv6 ip address, it put [] into the ip address and client are able to parsing that format.

Nowdays，many enviroment is tranfering to Ipv6.So，supporting Ipv6 is very important.When will bookkeeper support ipv6 feature? @sijie

@zongtanghu - Agreed. We are looking into how to support ipv6. One of the problems we have regarding this is that bookkeeper is using ip:port as the identifier. We are looking into how to change bookie id advertisement and be able to support ip address changes, and also for ipv6 as well. I am writing up a BP (bookkeeper proposal) around this topic and will be sharing it with the community next week.

Okay,thanks for you reply.It's a very meaningful thing.Later,I will look at bookkeeper's source code in depth, and research to see Bookkeeper can be applied to which business scenarios for us. @sijie
