I dont know anything about ip addresses but any chance that number from coasterrumors has anything to do with it?
Unfortunately, no. Though an IP address teaser would be cryptic and not something I'd put past Don. Unfortunately, in the case of IP addresses, each Octet (the set of numbers between the periods) is an 8-bit value and can range only from 000 to 255. The numbers in the coasterrumors post were 839.445, which unfortunately are not valid octets.
But I must admit, that was very clever sleuthing. Good job!
Thanks for the help!
