'address mask not contiguous' ie contiguous one bits from the left.

It's not clear from this where the .218 address shown by sockstat comes
from, or which interface it's assigned to?  Maybe I've pruned too much? 
'ifconfig -au' would be informative.  Anyway .. 

Assuming fxp0 with address .219 is the A address of host w00f on a /24
net as indicated by the fxp0 netmask, then you shouldn't have another
interface on that subnet except as a /32 (single IP address), though
apparently not an alias as such, being on another interface.

I'm not clear how this works through your switch, but try xl1 (.244)
with a 255.255.255.255 (0xffffffff) netmask. Then when you tell named
which addresses to bind to it'll be dealing with addresses it can find.
