3.7.4 Private IP Addresses
Every machine on the Internet must have a unique address. If your networks are isolated from the
Internet, for example, only between your two branch offices, you can assign any IP addresses to
the hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has
reserved the following three blocks of IP addresses specifically for private networks:
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
You can obtain your IP address from the IANA, from an ISP or it can be assigned from a private
network. If you belong to a small organization and your Internet access is through an ISP, the ISP
can provide you with the Internet addresses for your local networks. On the other hand, if you are
part of a much larger organization, you should consult your network administrator for the
appropriate IP addresses.

3.8 Nailed-Up Connection (PPP)

A nailed-up connection is a dial-up line where the connection is always up regardless of traffic
demand. The TELKOM ADSL 5100 does two things when you specify a nailed-up connection.
The first is that idle timeout is disabled. The second is that the TELKOM ADSL 5100 will try to
bring up the connection when turned on and whenever the connection is down. A nailed-up
connection can be very expensive for obvious reasons.
Do not specify a nailed-up connection unless your telephone company offers flat-rate service or
you need a constant connection and the cost is of no concern

3.9 NAT

NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host
in a packet, for example, the source address of an outgoing packet, used within one network to a
different IP address known within another network.
