Comment:

 This is because the VCC compiler builds expressions left to right, so
 seeing server.ip it has type "IP", then you try to add a string to that
 and it barfs.

 The workaround (see above) starts out with STRING, then adds IP, but since
 everything, including IP, can be converted to string, that works out fine.
