Hello hello,
I have a pretty basic question here, is the class C net address
193.0.0 valid ?
Currently this is the address of our (internal) net. We are
going to be hooking this net to a firewall which will then be
connected to the Internet. Basically, I don't want to have to renumber
all of these address if I don't have to. (I know it should of
been done right the first time and it would be the PC thing to
do, but everything in time. If we could put it off that would be great.)
I know how to keep DNS and mail straight so that it can forward all
information to the appropriate host, but all is lost if the IANA assigns
193.0.0 to someone else that we may want to (say) send mail to.
(I know they haven't yet; at least up till recently).
I can not find anywhere in the RFC's that says that this is a valid
(invalid) Class C address and therefore will potentially be assigned to
someone. I'm under the impression that having the 2nd and 3rd quads of a
class C address being zeroed is invalid. (Since Internet hosts still
have to be able to handle broadcasts of 0 and -1, with the host number masked
out by the netmask. This would mean a broadcast to all 193.x.y.z hosts is
possible ?)
Also, if this *is* valid, why hasn't it already been assigned ??? It
seems like the IANA has done a pretty good job of *not* assigning it.
If it *is* valid, could you give me a reference;I'm surely
missing more detail here. Or if it is *not* valid, would anyone
have a suggestion of an automated way to change a large amount of hosts
(PC's and UNIX).
Thanks in advance,
greg
