The PreferredAddress structure has a variable length field right in the middle of it.  Since the CID is the only variable length field, we could make it slightly easier to implement by moving the CID to the end:

```
  struct {
     opaque ipv4Address[4];
     uint16 ipv4Port;
     opaque ipv6Address[16];
     uint16 ipv6Port;
     opaque statelessResetToken[16];
     opaque connectionId<0..18>;
   } PreferredAddress;
```
