[Slugnet] 255 octet in an IP address OK?

[Chng Tiak-Jung]

I think what he meant was: isn't 255 reserved for some special purpose, just
like 0 ?

But, I thought is this case, it is still alright because the special meaning
is only for the last octet - where 0 => network address, 255 => broadcast
address.

Maybe someone who is familiar with the IP network standard should clarify.
