113 network to off-site hosts.  Subnetworks are useful because
114 they allow a site to hide their local topology, requiring only a single
116 it also means that local network numbers may be locally administered.
117 The standard describing this change in Internet addressing is RFC-950.
119 To set up local subnets one must first decide how the available
120 address space (the Internet ``host part'' of the 32-bit address)
123 number have a 24-bit host address space with which to work, sites with a
124 class B network number have a 16-bit host address space, while sites with
125 a class C network number have an 8-bit host address space\**.

131 To define local subnets you must steal some bits
132 from the local host address space for use in extending the network
134 addresses is done only for local networks; i.e. it is not visible
135 to hosts off-site.  For example, if your site has a class B network
137 the network number, 16 bits, and the host number, another
138 16 bits.  To define 254 local subnets, each
139 possessing at most 255 hosts, 8 bits may be taken from the local part.
140 (The use of subnets 0 and all-1's, 255 in this example, is discouraged
143 numbers are then constructed by concatenating the original 16-bit network
144 number with the extra 8 bits containing the local subnet number.
146 The existence of local subnets is communicated to the system at the time a
155 network part as well as the portion of the local part
160 of the local part have been reserved for defining subnets;
171 ``128.32.1.7'' (host 7 on network 128.32.1).  Hosts \fIm\fP on
172 sub-network \fIn\fP of this network would then have addresses of
173 the form ``128.32.\fIn\fP.\fIm\fP'';  for example, host
182 according to RFC-919 is the address with a host part of all 1's.
183 The address used by 4.2BSD was the address with a host part of 0.
191 as for normal host addresses, with the remaining host part set to 1's
194 sent to the logical-network broadcast address as well as those sent
195 to the subnet broadcast address, and when using an all-1's broadcast,
196 also recognize and receive packets sent to host 0 as a broadcast.
