Hmmm... thats my bad. I have a fsck-up in my rc.conf on that box...


I guess when one leaves out the 'netmask' keyword, the next parameter
after the IP becomes the broadcast address.

I'm actually quite surprised and perplexed as to how this box has been
able to communicate to other prefixes on the network :)

Thanks for the keen eye. You've most certainly saved me some future anguish!
