I would ask before you buy, however, any VPS host offering IRC enabled VPS will likely have some form of DDOS protection, simply because IRC just seems to attract DDOS attacks. Im sure I don't know as much as IRCCo Jeff, however, DDOS protection should be at the network level, not at the server level and so a VPS node ( being a dedicated server itself ) should work just fine with DDOS protection. As for the financial ramifications, that just depends on the host. Typically there is a premium charge for DDOS protection.
