    struct {
-     enum { IPv4(4), IPv6(6), (15) } ipVersion;
-     opaque ipAddress<4..2^8-1>;
+     opaque ipv4Address<0..2^8-1>;
+     opaque ipv6Address<0..2^8-1>;
      uint16 port;

I think the intent is to deal with anycast, but I could see it being used defensively against attacks.

As for P2P there is a strong case for both ends to use a known fixed port. However, I could also see this as a way to load balance multiple connections to multiple threads or processes.
