point.com) and one or more IP addresses (such as 192.34.45.8). A DNS server keeps a database of Internet servers and their respective domain names and IP addresses, so that when a domain name is requested (as in typing "Broadbandaccess point.com" into your Internet browser), the user is sent to the proper IP address. The DNS server IP address used by the computers on your home network is the location of the DNS server your ISP has assigned to you. DSL Modem: DSL stands for Digital Subscriber Line. A DSL modem uses your existing phone lines to transmit data at high speeds. Ethernet: A standard for computer networks. Ethernet networks are connected by special cables and hubs, and move data around at up to 10/100 million bits per second (Mbps). IP Address and Network (Subnet) Mask: IP stands for Internet Protocol. An IP address consists of a series of four numbers separated by periods, that identifies a single, unique Internet computer host in an IP network. Example: 192.168.2.1. It consists of 2 portions: the IP network address, and the host identifier. The IP address is a 32-bit binary pattern, which can be represented as four cascaded decimal numbers separated by ".": aaa.aaa.aaa.aaa, where each "aaa" can be anything from 000 to 255, or as four cascaded binary numbers separated by ".": bbbbbbbb.bbbbbbbb.bbbbbbbb.bbbbbbbb, where each "b" can either be 0 or 1. A network mask is also a 32-bit binary pattern, and consists of consecutive leading 1's followed by consecutive trailing 0's, such as 11111111.11111111.11111111.00000000. Therefore sometimes a network mask can also be described simply as "x" number of leading 1's. When both are represented side by side in their binary forms, all bits in the IP address that correspond to 1's in the network mask become part of the IP network address, and the remaining bits correspond to the host ID. For example, if the IP address for a device is, in its binary form, 11011001.10110000.10010000.00000111, and if its network mask is, 11111111.11111111.11110000.00000000 It means the device's network address is 11011001.10110000.10010000.00000000, and its host ID is, 00000000.00000000.00000000.00000111. This is a convenient and efficient method for access points to route IP packets to their destination. 84

point.com) and one or more IP addresses (such as 192.34.45.8). A DNS server
keeps a database of Internet servers and their respective domain names and
IP addresses, so that when a domain name is requested (as in typing
"Broadbandaccess point.com" into your Internet browser), the user is sent to
the proper IP address. The DNS server IP address used by the computers on
your home network is the location of the DNS server your ISP has assigned to
you.
DSL Modem:
DSL stands for Digital Subscriber Line. A DSL modem uses your
existing phone lines to transmit data at high speeds.
Ethernet:
A standard for computer networks. Ethernet networks are
connected by special cables and hubs, and move data around at up to 10/100
million bits per second (Mbps).
IP Address and Network (Subnet) Mask:
IP stands for Internet Protocol. An IP
address consists of a series of four numbers separated by periods, that
identifies a single, unique Internet computer host in an IP network. Example:
192.168.2.1. It consists of 2 portions: the IP network address, and the host
identifier.
The IP address is a 32-bit binary pattern, which can be represented as four
cascaded decimal numbers separated by “.”: aaa.aaa.aaa.aaa, where each
“aaa” can be anything from 000 to 255, or as four cascaded binary numbers
separated by “.”: bbbbbbbb.bbbbbbbb.bbbbbbbb.bbbbbbbb, where each “b”
can either be 0 or 1.
A network mask is also a 32-bit binary pattern, and consists of consecutive
leading
1’s followed by consecutive trailing 0’s, such as
11111111.11111111.11111111.00000000. Therefore sometimes a network
mask can also be described simply as “x” number of
leading 1’s.
When both are represented side by side in their binary forms, all bits in the IP
address that correspond to 1’s in the network mask become part of the IP
network address, and the remaining bits correspond to the host ID.
For example, if the IP address for a device is, in its binary form,
11011001.10110000.1001
0000.00000111, and if its network mask is,
11111111.11111111.11110000.00000000
It means the device’s network address is
11011001.10110000.1001
0000.00000000, and its host ID is,
00000000.00000000.00000000.00000111
. This is a convenient and efficient
method for access points to route IP packets to their destination.
