4.1 IPV4
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.
