Do you mean clientMachine's IP? Take a look at [^clientMachine-call-path.jpeg]
The clientMachine's IP is get from Server property InetAddress addr.
I think we can get client's IP from clientName, but I'm not sure how to decode
clientname.

> When execute a put operation via router, the NameNode will choose block
> location for the router, not for the real client. This will affect the file's
> locality.
> I think on both NameNode and Router, we should add a new addBlock method, or
> add a parameter for the current addBlock method, to pass the real client
> information.
