Node Identity

Hello,

I cannot find any documentation about a node's identity. I'm curious if it's currently based off of its IP address, and if it's possible to pass an identity to the node instead. This would allow us to use dynamic IPs while maintaining identities across restarts. This is common in kubernetes statefulsets, where maintaining the same identity would allow restarts to become healthy faster.

Thanks!

No files, tests, or entry points are identified. Start by locating how node identity and peer addressing are represented and persisted, then check existing documentation and Kubernetes-related deployment assumptions. Done would require a clearly defined identity mechanism or an explicit documented limitation, with tests covering identity across dynamic-IP restarts.
