// perNodeHostBits defines the number of host bits to be configured per node.
  // A subnet mask determines how much of the address is used for network bits
  // and host bits. For example an IPv4 address of 192.168.0.0/24, splits the
  // address into 24 bits for the network portion and 8 bits for the host portion.
  // To allocate 256 IPs, set this field to 8 (a /24 mask for IPv4 or a /120 for IPv6).
  // Minimum value is 4 (16 IPs).
  // This field is immutable.

## Redirection

As ztunnel aims to transparently encrypt and route users traffic, we need a mechanism to capture all traffic entering and leaving "mesh" pods.
This is a security critical task: if the ztunnel can be bypassed, authorization policies can be bypassed.

Redirection must meet these requirements:
* All traffic *egressing* a pod in the mesh should be redirected to the node-local ztunnel on port 15001.

**`krt`** is a very high level wrapper around Kubernetes informers, building on top of `kclient`.

See the [krt README](../../pkg/kube/krt/README.md) for more information.

*krt is currently experimental; please ask maintainers before utilizing it in new areas.*
