FAQ: Can I get the device's current IP in my BCL program?

			* ''Can I get the device's current IP in my BCL program?''
			Yes, to do so use '''SPRINTF$''' with the '''%A''' format string:

			<pre>
			ip$=SPRINTF$("%A",1)
			</pre>

			The '''ip$''' will contain e.g.:

			192.168.2.100

			To obtain the IP address with leading zeroes use:

			ip$=SPRINTF$("%1A",1)

			The '''ip$''' will then contain e.g.:

			192.168.002.100

			See more in the chapter Formatted String Conversions - SPRINTF of the BCL Programmers Manual.

 == Multicast ==
-* open UDP handle with a multicast address
+BCL supports up to 16 IP multicast groups at a time. The subscription, periodic membership reporting as well as group leaving is performed automatically by the firmware and does not have to be handled by the BCL application. IGMP version 1 and 2 is supported.
