* n represents a digit of the network number; h represents a digit of the host number.

Class D addresses are used for multicast applications as assigned by the Internet Assigned Numbers Authority (IANA).

 

For more information on Internet addresses, subnet masks, and

 

variable length subnet masks, refer to Using NETBuilder Family

 

Software.

 

IPX

Leading zeros can be omitted. Consists of an ampersand (&) followed

 

by a network address, which contains eight hexadecimal digits,

 

followed by the MAC address.

 

You may need to enter an IPX address when using the bridge/router

 

for IPX routing. The network address uniquely distinguishes one IPX

 

network from all other IPX networks. The following example

 

addresses are the same:

 

 

&00003333%080002005678

 

&3333%080002005678

 

OSI

Open System Interconnection (OSI) network addresses are called

 

network service access points (NSAPs). NSAPs are of variable length

 

and format, although they are always considered to have the

 

following three parts:

 

 

Area address (variable length)

 

System ID (six octets)

 

 

N-selector (one octet)

 

 

The system ID and N-selector are the last seven octets of the MAC

 

address, and the area address is everything but the system ID and

 

N-selector. The following is an example of an OSI address:

 

/49/0053080002A0089D01

 

 

where the area address is:

/49/0053

 

the system ID is:

080002A0089D

 

and the N-selector is:

01

 

For more information on the OSI addressing scheme, OSI routing

 

domains, and area addresses, refer to Using NETBuilder Family

 

Software.

 

VIP

A VINES Internet Protocol (VIP) address is globally unique, fixed, and

 

permanent for servers and routers only. Each node has a two-field,

 

48-bit Internet address, which is derived from the 32-bit VINES

 

network number and the 16-bit subnetwork number.

The Internet address has eight hexadecimal digits (VIP network ID) and four hexadecimal digits (subnetwork ID) separated by a colon (:). The Internet address (logical network) is independent of any data link layer address assigned to a node on a physical medium. The following is an example of a VIP address:

02A01339:0001
