```suggestion
consider the client address to have been validated.

Additionally, if a server sends a packet carrying a Source Connection
ID field that has at least 64 bits of entropy to a client address,
and if the server subsequently receives a packet from the client
carrying this server-generated connection ID in its Destination
Connection ID field, the server MAY consider the address to be
validated.
```
