% host core3.sfrn.ca
core3.sfrn.ca.rcn.net has address 208.59.222.0

Been up and running fine for the past 11 months, happy loopback 
in ISIS/iBGP/EBGP converstions. The largest hurdle was getting the
knuckle-draggers to not be confused or believe it an error.

I would have to ask why you would think it would NOT be valid? If
there is a vendor implementation that has probelems with it, that 
would be a bug, and I would consider it one for anyhting past 1994
vintage code.

Cheers,

Joe
