In this example, the default gateway uses the IP address 192.168.4.1, which is resolved into a MAC address with ARP in the usual way. The destination IP address remains 192.168.12.3, but the next-hop MAC address is that of the gateway, rather than of the ultimate destination.
On Windows XP, the server, by default, gets the IP address 192.168.0.1. (This default can be changed within the interface settings of the network adapter or in the Windows Registry .) It provides NAT services to the entire 192.168.0.x subnet, even if the address on the client was set manually, not by the DHCP server.
In Internet networking, a private network is a computer network that uses a private address space of IP addresses.These addresses are commonly used for local area networks (LANs) in residential, office, and enterprise environments.
Some large / 8 blocks of IPv4 addresses, the former Class A network blocks, are assigned in whole to single organizations or related groups of organizations, either by the Internet Corporation for Assigned Names and Numbers (ICANN), through the Internet Assigned Numbers Authority (IANA), or a regional Internet registry.
Network diagram with IP network addresses indicated e.g. 192.168.100.3.. A network address is an identifier for a node or host on a telecommunications network.Network addresses are designed to be unique identifiers across the network, although some networks allow for local, private addresses, or locally administered addresses that may not be unique.

Address of the server: 192.168.1.2; Address of a local computer: 192.168.1.100; If a packet is sent to 203.0.113.1 by a computer at 192.168.1.100, the packet would normally be routed to the default gateway (the router) [e] A router with the NAT loopback feature detects that 203.0.113.1 is the address of its WAN interface, and treats the packet ...
This allows for 62 host combinations (2 6 −2). In general, the number of available hosts on a subnet is 2 h −2, where h is the number of bits used for the host portion of the address. The number of available subnets is 2 n, where n is the number of bits used for the network portion of the address.
