EMWIN Port 2211

At the request of Antonio Querubin, IANA (Internet Assigned Number Authority), assigned port 2211 for the EMWIN (Emergency Managers Information Network) data stream in March of 2008.  The ByteBlaster network presently uses port 1000/tcp for distributing EMWIN data and ByteBlaster server lists. 

I am glad to see a recognized port adopted (Thanks Antonio).  I guess I just let this information get by me.  I will be running some experiments to see what problems users would encounter switching from port 1000 to 2211.  I am sure some users have opened their firewall ports for outbound connections to port 1000.

There is presently one ByteBlaster server running on port 2211.  I may change my server for testing.  Having a couple of servers on port 2211 will make the transistion easier to adopt.

Multicast Address

I knew that EMWIN was assigned the multicast address  I never had access to a multicast network, so I did not do anything with this information.  I am considering adding support for transmitting and receiving data by multicast.
