{6} We can reword the Peer Network Address section to read:
Peer Network Address

Peer network addresses use net.p2p for transport, to indicate the use of the
Windows peer network transport. When not using a resolver, you must specify
the peer network name as well as a unique path and port. Using and
configuring peer networks is beyond the scope of this book, and you will see
very little mention of peer networks in subsequent chapters.

{166}: In example 4-11, when the overrideConfig argument is true and a
throttling behaviour is already present, the existing behaviour will be
removed but not replaced (because the null reference condition will not
be satisfied).
Here is the correct code:

public void SetThrottle(ServiceThrottlingBehavior serviceThrottle,
                        bool overrideConfig)
{
   if(State == CommunicationState.Opened)
   {
      throw new InvalidOperationException("Host is already opened");
   }
   ServiceThrottlingBehavior throttle =
                    Description.Behaviors.Find<ServiceThrottlingBehavior>();
   if(throttle == null)
   {
      Description.Behaviors.Add(serviceThrottle);
      return;
   }
   if(overrideConfig == false)
   {
      return;
   }
   Description.Behaviors.Remove(throttle);
   Description.Behaviors.Add(serviceThrottle);
}
