Cisco Flash presents the following information:
62. What is the maximum length of an IPX address?
A. 32 bits
B. 80 bits
C. 48 bits
D. None of the above
Answer: B
Interconnecting Cisco Network Devices under Configuring IPX Routing that "The network number can be a number in the range 1 to FFFFFFFD. You do not need to specify leading zeros". No mention is made of node addressing. Later in the same chapter, page 343, Figure 10-14 shows three workstations, one with network number 9e.0800.4313.13.df56 (sic) with novell-ether encapsulation, 6c.0800.1213.13de (sic) with sap encapsulation, 4a.1234.0000.abcd (sic) with SAP encapsulation. 9e, 6c and 4a are identified as network numbers.
Odom's book has very good documentation on this matter. The size of an IPX address is ten bytes, 4 (4*8 = 32 bits) for the network and 6 (6*8 = 48 bits) for the node. There is no mention of variations in IPX addressing between 802.3 and 802.2. I've looked at a considerable number of IPX addresses, albeit using SAP (802.2) encapsulation. Is the node address for network 9e, above, a typo?
Every reference in Lammle's CCNA Study Guide prefaces IPX network numbers with 0x, for example 0x12db8494 and 0xcc715b00. Since we know that each byte holds two hex digits and there are only four bytes or eight hex digits in a network number, is the 0x prefix a nomenclature just to indicate that the following number is in hex and we can discard the 0x with no ill effects? Is this a "standard", if so, what is the source? I've seen X'12db8494' and 12db8494H used before, but not Lammle's method. Lammle doesn't mention this "standard" in his section on IPX Addressing.
