IP (Internet Protocol)
TCP/IP protocol on the Internet. IP is responsible for addressing parties in a Network
using IP addresses and routes data from the sender to the recipient. IP determines the
paths (routing) along which the data packets travel.
IP address
A unique address for a network component within a network on the basis of the TCP/IP
protocols (e.g. LAN, Internet). On the Internet, domain names are usually assigned
instead of IP addresses. DNS assigns the corresponding IP address to the domain name.
The IP address has four parts (decimal numbers between 0 and 255) separated by full
stops (e.g. 230.94.233.2).
The IP address is made up of the network number and the number of the Network sub-
scribers (e.g. phone). Depending on the Subnet mask, the front one, two or three
parts make up the network number and the rest of the IP address addresses the network
component. The network number of all the components in any one network must be
identical.
IP addresses can be assigned automatically with DHCP (dynamic IP addresses) or manu-
ally (static IP addresses).
See also: DHCP.
IP pool range
Range of IP addresses that the DHCP server can use to assign dynamic IP addresses.
ISP
Internet Service Provider
See Internet Service Provider.
L
LAN
Local Area Network
Network with a restricted physical range. A LAN can be wireless (WLAN) and/or wired.
Local IP Address
The local or private IP address is the address for a network component in the local net-
work (LAN). The network operator can assign any address he or she wants. Devices that
act as a link from a local network to the Internet (gateway or router) have a public and
a private IP address.
See also IP address.
Local SIP Port
See SIP port/Local SIP port.
M
MAC address
Media Access Control Address
Hardware address by means of which each network device (e.g. network card, switch,
phone) can be uniquely identified worldwide. This consists of 6 parts (hexadecimal
numbers), which are separated by "-"(e.g. 00-90-65-44-00-3A).
The MAC address is assigned by the manufacturer and cannot be changed.
Mbps
Million bits per second
Unit of the transmission speed in a network.
