Address Type
Local Host
Because IP addresses must be unique all over the world, you cannot just select random
addresses. There are three address domains to use if you want to set up a private IP-
based network. These cannot get any connection from the rest of the Internet, because
they cannot be transmitted over the Internet. These address domains are specified in
RFC 1597 and listed in
Table 30.3 Private IP Address Domains
Network/Netmask
10.0.0.0/255.0.0.0
172.16.0.0/255.240.0.0
192.168.0.0/255.255.0.0
30.2 IPv6—The Next Generation
Internet
Due to the emergence of the WWW (World Wide Web), the Internet has experienced
explosive growth with an increasing number of computers communicating via TCP/IP
in the past fifteen years. Since Tim Berners-Lee at CERN
.cern.ch) invented the WWW in 1990, the number of Internet hosts has grown from
a few thousand to about a hundred million.
As mentioned, an IPv4 address consists of only 32 bits. Also, quite a few IP addresses
are lost—they cannot be used due to the way in which networks are organized. The
Description
ample therefore results in 192.168.0.255. This address cannot
be assigned to any hosts.
The address 127.0.0.1 is assigned to the "loopback device"
on each host. A connection can be set up to your own machine
with this address.
