2-4 IP
IP is an acronym for Internet Protocol. It is a protocol used for communicating data across an
internet network.
IP is a "best effort" system, which means that no packet of information sent over is assured to
reach its destination in the same condition it was sent. Each device connected to a Local Area
Network (LAN) or Wide Area Network (WAN) is given an Internet Protocol address, and this
IP address is used to identify the device uniquely among all other devices connected to the
extended network.
The current version of the Internet protocol is IPv4, which has 32-bits Internet Protocol
addresses allowing for in excess of four billion unique addresses. This number is reduced
drastically by the practice of webmasters taking addresses in large blocks, the bulk of which
remain unused. There is a rather substantial movement to adopt a new version of the Internet
Protocol,
IPv6,
which would have 128-bits Internet Protocol addresses. This number can be
represented roughly by a three with thirty-nine zeroes after it. However, IPv4 is still the
protocol of choice for most of the Internet.

The IPv4 address for the switch could be obtained via DHCP Server for VLAN 1. To manually
configure an address, you need to change the switch's default settings to values that are
compatible with your network. You may also need to establish a default gateway between the
switch and management stations that exist on another network segment.
Configure the switch-managed IP information on this page.
The Configured column is used to view or change the IP configuration.
The Current column is used to show the active IP configuration.
Web Interface
To configure an IP address in the web interface:
1. Click System, IP Configuration.
2. Specify the IPv4 settings, and enable DNS proxy service if required.
3. Click Save.
