Tips and Troubleshooting
Choosing a multicast IP address
The range of Multicast IP addresses is 220.127.116.11 to 18.104.22.168. Some addresses, as specified in the table below, are reserved for specific purposes. When specifying a multicast IP address for a ConferenceXP venue, you’ll need to make sure the address you specify is not a reserved, well-known address. If the venue is for an internal-only network, select a multicast IP address in the limited scoped range. If the venue is for a network that supports external addresses, select a multicast IP address in the globally scoped range.
Multicast IP Address Range and Description:
- 22.214.171.124 – 126.96.36.199: Reserved for "well-known" multicast IP addresses
- 188.8.131.52 – 184.108.40.206: Globally scoped addresses (that is, Internet or external) multicast IP addresses
- 220.127.116.11 – 18.104.22.168: Limited scoped (that is, internal or local) multicast IP addresses
For more information about multicast addresses, see: http://en.wikipedia.org/wiki/Multicast_address
Client Timeout on first access
If your venue service does not receive very many hits, the IIS application pool process my reach the idle timeout (default 20 minutes). In this case, the response to the next hit may be delayed long enought that the CXP Client will timeout (default 10 seconds), and the client will show only the Local Venue.
To prevent the application pool thread timeout in IIS:
- Run IIS Manger, open the Application Pools node
- Right-click DefaultAppPool, select Properties
- Select Performance Tab; Set the Idle Timeout to greater than maximum time between hits.
