Hi @fengmao31 ,

You can get the IP and ports of each discovered entity via the use of discovery callbacks. You can check this link for more information regarding the specifics of the implementation of a custom listener. The discovery info passed to the discovery callbacks contains, among other things the locator information (protocol, IP and port) for that entity.

I'm moving this conversation to Discussions since it's not an issue.
