What are the IP-addresses for demo, contest and real accounts?

For MetaTrader 4 users:
When you launch the client terminal, it connects to our server loading a list of IP addresses. If you indicate an IP address, not a symbol type server name when you log in for the first time, the next time you launch Metatrader 4 the application automatically loads the names of available trading servers. The IP address you previously typed in will be changed to the symbol type name of the server (for example «PSS-Live», » or «PSS-Demo»). Should one of the servers become unavailable, the client terminal automatically switches to the next available server.
For live accounts, please choose «PSS-Live» server from the list of the available servers. In case you cannot find such a server name please type in mt4.psstr.com:443.
For your demo accounts please choose «PSS-Demo» from the list of the available servers. In case you can not find such a server name please type in mt4d.psstr.com:443.
