No need to apologize, I misspoke. In fact I think I misspoke again
above, stating a 0 could be in the first three octets, 0 in the first
octet is reserved as per rfc 3330,1700. Whether you may see 0 in the
first octet as a source only address in an IP header (broadcast?) is
beyond my ken, but for sure you won't see it in the first octet of a
machine's IP address.

_Now_, this is getting really anal...
