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 vehicle computer. If the IP type is Static, the
values displayed were input manually in the
IP Config tab. See IP Mode on page 4-17.
IP
Address
Displays the vehicle computer’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.
