problem with IPV4 when I try to create new venue
- Hi! I'm starting with conferenceXP ...
I have a problem when I try to create a new venue. In the IP address box, I tried with a 192.168.x.x IP, but an error message appears: "IP Address" is not a valid IP address.
What can I do? Help please!

- Hello,
To create a venue, you will need to enter in a multicast IP address (I alway do something in the 239.0.0.x range).
It doesn't matter that this IP address is not assigned to any specific machine (like a 192.168.x.x one might be) since the address is actually for a group instead of a specific machine. The way multicasting works is every machine has its own IP address (like 192.168.1.2), but each machine also joins a multicast group, and every machine in the group shares the same multicast address (so effectively, the machines have two addresses -- the normal IP and the multicast group one). Any traffic sent to the multicast address is actually received by all members of the group, just as if someone had sent separate unicast traffic to each machine.
Also, the server with the venue service on it is really nothing more than a bulletin board where CXP posts different multicast group addresses for people to join. As such, it doesn't even need to be in the same multicast cloud as the machines you want to use CXP with since it never connects to the group itself. As long as the computers you want to use CXP with are behind the same router, or on the same subnet, or multicast enabled, they can join the group multicast address and work together.
Hope this helps,
Adam
