IP address
A unique address for a network component within a network based on 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
subscriber (e.g., phone). Depending on the Subnet mask, the first 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
manually (fixed IP addresses).
See also: DHCP.
IP pool range
Range of IP addresses that the DHCP server can use to assign dynamic IP addresses.
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
network (LAN). The network operator can assign any address they want. 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. It consists of six parts (hexadecimal
numbers) 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.
MRU
Maximum Receive Unit
Defines the maximum user data volume within a data packet.
MTU
Maximum Transmission Unit
Defines the maximum length of a data packet that can be carried over the network at
a time.
