dynamic host Configuration Protocol (dhCP) is an auto configuration protocol that assigns
IP Addresses to devices connected a network segment requesting the DHCP protocol. This is a
very efficient way to assign IP Addresses within a defined Subnet. DHCP will automatically assign,
recycle and maintain the IP Addresses allowed by the DHCP Server settings. This is the default
for all StreamNet devices, if the StreamNet device fails to locate a suitable DHCP server it will then
change to an Auto IP mode.
Static iP addressing is a method in which every device is given a specific controlled IP Address on
the network. This method ensures that the device IP Address will not overlap or conflict with other
IP Addresses in the network. This method requires a great deal recording, tracking and managing
assigned IP Addresses to ensure a duplicate Address is not assigned within the Subnet. Typically
used when an IP Range would consume too many available IP Addresses.
NOTE: There is no assurance that another device with a static IP address will not »
overlap.
auto iP is a module that allows for the Automatic assignment of an IP Address to devices on the
network within a given range without the use of a DHCP server. Much like the DHCP protocol, Auto
IP allows for a device to receive an IP Address automatically on startup.
Default Auto IP settings in StreamNet Dealer Setup software:
DigiLinX Dealer Setup 2.56 and earlier versions •
Auto IP Range: 10.15.0.1 – 10.15.255.255, Subnet Mask: 255.0.0.0 •
Default Gateway: 0.0.0.0, DHCP: Not in Use •
StreamNet Dealer Setup 2.60.04 and later versions •
Auto IP Range: 169.254.1.0 – 169.254.254.255, Subnet Mask: 255.255.0.0 •
Default Gateway: 0.0.0.0, DHCP: On by Default •
iP address ranges
Class a comprises networks 1.0.0.0 through 127.0.0.0. The network number is contained in the first
octet. This class provides for a 24-bit host part, allowing roughly 1.6 million hosts per network.
Class B contains networks 128.0.0.0 through 191.255.0.0; the network number is in the first two
octets. This class allows for 16,320 nets with 65,024 hosts each.
Class C networks range from 192.0.0.0 through 223.255.255.0, with the network number contained
in the first three octets. This class allows for nearly 2 million networks with up to 254 hosts.
Classes d, e, and f
Addresses falling into the range of 224.0.0.0 through 254.0.0.0 are either experimental or are re-
served for special purpose use and don’t specify any network. IP Multicast, which is a service that
allows material to be transmitted to many points on an internet at one time, has been assigned
addresses from within this range.
