Networking Terms
DHCP: Dynamic Host Configuration Protocol - A protocol for automated assigning of dynamic IP addresses to
devices on a network. DHCP allows IP addresses to be pooled and assigned as needed to clients.
Auto IP: If the XStream-PKG-E Ethernet RF Modem sits on a network that does not include a DHCP server, the
built-in “Auto IP” feature will enable the modem to assign itself an IP address. The Intelligent XPort Ethernet
Port will communicate with the server and determine what IP addresses are available. The Ethernet RF Modem
will then assign itself the first available IP address it finds.
IP (Logical) Address: A logical address used in TCP/IP networking. This unique 32-bit number is divided into
four groups of octets (8-bit bytes) that are separated by periods.
Hardware (Physical or MAC) Address: Number that uniquely identifies a network node. The hardware
address is hard-coded to the device at the factory by the manufacturer. The hardware address is printed on the
Ethernet port inside the XStream-PKG-R RF Modem.
Subnet: A portion of a network that shares a network address with other portions of a network and is
distinguished by a subnet number. Subnets are formed when an IP network is broken down into smaller
networks using a subnet mask.
Subnet Mask: A ʺfilterʺ that tells the server whether a node is on the local network or a remote network. If the
server IP address and the remote IP address appear the same after the filter, the remote host is assumed to be
on the same local network. Otherwise, the gateway is used. When combined with an IP address, the subnet
mask informs the rest of the network as to what kind of subnet the device is on.
