• IP Address
The Internet Protocol (IP) in its most frequently used form has a
32-bit address which is used to identify the senders and receivers
of packets unambiguously. You can send requests in the Web to
remote servers or send e-mails, and the opposite terminal will
know from where the request or the e-mail comes. There are pub-
lic and private IP addresses. Private IP addresses are preferably
assigned by routers if a group of computers is used in a private or
enterprise network. Such addresses may read, for instance,
192.168.0.1.
• IPCONFIG
This is an auxiliary program used by Windows computers to check
or modify the proper IP settings.
• ISP
An Internet Service Provider (ISP) is a provider of Internet services
or related services, such as the hosting of websites or website
creation.
• LAN
A LAN (Local Area Network) is a local network which is usually set
up within a building. Here, all computers involved share local ser-
vices (e.g. DHCP or file server). With the help of a WLAN, a LAN
may also comprise and network several buildings.
• MAC Address
The MAC (Media Access Control) address is the unambiguous
hardware address of a network interface. Each hardware manu-
facturer assigns his proper MAC addresses from his own number
pool. As a result, manufacturers can be assigned on the MAC
address level.
• NAT, Network Address Translation
Translation of an IP address in one network into another IP
address in another network. As a result, many computers in one
network can be displayed to the outside with a single IP address.
NAT is often used by SOHO routers or in BAT 11b Wireless Ethernet
ACs if several clients are connected via a switch.
• Network Mask
See subnet mask.
