I can confirm this from the sources. Why it is done like this I don't
know.

It is explicitly done in the source so I can only assume there is some
intention behind it, but the source history gives no clues (added in acl.c
revision 1.25 1996/07/23).

But at least it is somewhat consistent:

   IP matches uses 255.255.255.255 if no address could be found (dst,dstasn
acl)

   host/domain matches uses "none" if no host name could be found
(dstdomain/srcdomain acls).
