IP Explosion.... the term 'explosion' would be a killer term if the term was "dot com" or "tattoo" or any subject where the more of them that got created the more others would want them, you'd get real good $, but an IP address....you may choose to have many but it's not a hot commodity. Regardless of what you paid for it, just expose it in straight auctions, you may get something (and mention the 2003 or so creation date, who knows who it might sway lol...)
