Lan transport properties can exceed the maximum length.

The ipPort field used in the lan plugin contains a list of recent IP:port pairs which can hold up to 5 IPs. Each entry is about 11-21 chars long and therefore the overall size can exceed the MAX_PROPERTY_LENGTH of 100 (e.g. 21 * 5 = 105). Once the limit is reached contact exchanges always fail:
