that clients move connections to these dedicated addresses. Note that clients could
choose not to use the preferred address.

```suggestion
A server deployment could load balance among servers using simply source and
destination IP addresses and ports. Changes to the client's IP address or port of
could result in packets being forwarded to the wrong server. Such a server
deployment could use one of the following methods to for connection continuity
when a client's address changes.
```

```suggestion
* If servers can use other dedicated server IP addresses or ports than
the one that the client is initiating connections to, they could use the
preferred_address transport parameter to request
```

+Server deployments that use such load balancing might still allow for
+creation of a stateless reset oracle. Servers should take additional
+precautions in accordance with {{reset-oracle}}.

```suggestion
A server in a deployment that does not implement a solution to
maintain connection continuity during connection migration
SHOULD disallow it via the disable_active_migration transport
parameter.

Server deployments that use such load balancing might still allow for
creation of a stateless reset oracle, and should therefore follow the
guidelines in {{reset-oracle}}.
