net 39 was used to validate the CIDR-style of addressing. I was instructed to host the nameservers for the prefix and there was an experiment to announce various fragments of the space. You can find the experiment and its results in the RFC archives. Since that experiment, ARIN came into being as has ICANN. They have apparently seen fit to move the prefix back into reserved space, but have not "cleaned" up the DNS delegation. You may think of this announcemnt as a "network appendix", of little intrinsic value. You may also find that its a reasonable way to validate your filters... -- bill (still waiting for the other shoe to drop...)

I believe this is EP.Net LLC, a Bill Manning company.

Which seems to match who reserved the network. :-)
Why Bill / EP.Net is experimenting / leaking 39/8 is beyond me, but at least from where I sit it's as legitimate as any other announcement.
