Understanding IP Addresses
| |
Your IP address bitwise ANDed with the so called netmask yields your
network address. The network address bitwise ORed with the
negated netmask yields your so called broadcast address. The
IP address of the router through which you connect to the Internet is
referred to as the gateway.
A simple example is:
IP: 192.168.0.34 (0xc0a80022)
Mask: 255.255.255.240 (0xfffffff0)
Network: 192.168.0.32 (0xc0a80020 = 0xc0a80022 & 0xfffffff0)
Broadcast: 192.168.0.47 (0xc0a8002f = 0xc0a80020 | ~0x0f)
