IPv4 Status Fields
Field Description
IP Type Displays the IP type for the current profile:
DHCP
or
Static
. If the IP type is DHCP, leased IP
address and network address data appear for the reader. If the IP type is Static, the values
displayed were input manually in the
IP Config
tab on page 4-19 .
IP Address Displays the reader’s IP address. The Internet is a collection of networks with users that
communicate with each other. Each communication carries the address of the source and
destination networks and the particular machine within the network associated with the user
or host computer at each end. This address is called the IP address. Each node on the IP
network must be assigned a unique IP address that is made up of a network identifier and a
host identifier. The IP address as a dotted-decimal notation with the decimal value of each
octet separated by a period, for example, 192.168.7.27.
Subnet Displays the subnet address. Most TCP/IP networks use subnets to manage routed IP
addresses. Dividing an organization's network into subnets allows it to connect to the Internet
with a single shared network address, for example, 255.255.255.0.
Gateway Displays the gateway address. A gateway forwards IP packets to and from a remote
destination.
DCHP Server The Domain Name System (DNS) is a distributed Internet directory service. DNS translates
domain names and IP addresses, and controls Internet e-mail delivery. Most Internet services
require DNS to operate properly. If DNS is not configured, Web sites cannot be located or
e-mail delivery fails.
Lease Obtained Displays the date that the IP address was obtained.
Lease Expires Displays the date that the IP address expires and a new IP address is requested.
DNS Displays the IP address of the DNS server.
WINS WINS is a Microsoft Net BIOS name server. WINS eliminates the broadcasts needed to
resolve computer names to IP addresses by providing a cache or database of translations.
MAC An IEEE 48-bit address is assigned to the reader at the factory to uniquely identify the adapter
at the physical layer.
Host Name Displays the name of the reader.
