Ipx Addresses; Reserved Destination Socket Numbers - Black Box LRA001A-R2 User Manual

3.2 IPX Addresses

IPX addresses uniquely identify a particular node on an IPX network. IPX addresses are represented as:
net.node.socket
net—Uniquely identifies an IPX network with a number. This IPX network number is specified in 8-
digit hexadecimal format. The range of valid IPX network numbers for Router command-line
parameters is 1 to fffffffe. The IPX network number 0 is reserved for this network and should not be
used in any Router commands. The IPX network number ffffffff is reserved for broadcast and
should not be used in any Router commands.
node—Represents the Media Access Control (MAC) protocol address of an IPX node. For Ethernet, it
is the Ethernet address. The node number is a 12-digit hexadecimal number.
socket—A 4-digit hexadecimal number in the range of 1 to fffe. The socket specifies the process within
a router or NetWare server to which a packet will be sent. Leading zeros are not required. Missing
fields default to zero, which implies a wild-card condition.
Example IPX addresses
3.00801b0271ee.453
Packets with this destination address will be sent to IPX network 3, Ethernet address 00:80:1b:02:71:ee,
RIP process socket 453.
1993.02cf1f800022.452
Packets with this destination address will be sent to IPX network 1993, Ethernet address 02:cf:1f:80:00:22,
SAP process socket 452.

3.3 Reserved Destination Socket Numbers

The destination socket field contains the socket number of the packet's destination process. Sockets are
used to route packets to different processes within a single node. Table B-1 lists the reserved socket
numbers in NetWare:
