Tools Bof nanog 44

Greetings, It's not to late to think about sharing with your peers... Got a tool you use to monitor dns or ip hijacking, got some practices for monitoring your prefixes for anonlous events, have a commercial product you use that does one of these really well? Have some experience managing ipv6 addresses, or a dnssec toolkit? I'm sure your peers would love to hear about any of the above. Other topics are encouraged and invited. thanks joel
