B-1 Appendix B Understanding IP Addr essing This appendix is a brief general introduction to IP addr essing. A basic understanding of IP will help you in configuring the Netopia Router and using some of its power ful featur es, such as static routes and packet filtering.
B-2 Reference Guide About IP addr essing Ever y networking protocol uses some for m of addressing in or der to ensure that packets ar e delivered cor r ectly . In IP , individual network devices that are initial sour ces and final destinations of packets are usually called hosts, instead of nodes, but the two ter ms are inter- changeable.
Understanding IP Addressing B-3 Class A networks have a small number of possible network numbers, but a lar ge number of possible host numbers. Conversely , Class C networks have a small number of possible host numbers, but a lar ge number of possible network numbers.
B-4 Reference Guide the subnet numbers. Since the InterNIC assigns the network number proper , it should not change, so the subnet numbers must be created out of bits that would other wise be par t of the host numbers.
Understanding IP Addressing B-5 Note: If you receive an IP addr ess from an ISP , ther e must be a mask associated with that IP address. By using the IP addr ess with the mask you can discover exactly how many IP host addresses you actually have.
B-6 Reference Guide As you can see, subnet masks that allocate one, seven, or eight bits to subnets are useless for a Class C network. This is because binar y host addresses or subnet addr esses that are composed of all zeros or all ones ar e reser ved for br oadcasting (see “Broadcasts” on page B-16 ).
Understanding IP Addressing B-7 that allocates five bits to the host address and thr ee to the subnet address. This gives you a potential of six subnets of 30 machines each. 2. Deter mine the subnet mask Y ou can find the subnet mask associated with your subnetting choice in the table above.
B-8 Reference Guide 5. Deter mine the host addresses Finally , combine your subnet numbers with your host numbers to deter mine the actual IP addresses you may use for your 25 hosts. The first three bytes of the addr ess will always be 199.14.17, as assigned to you by InterNIC.
Understanding IP Addressing B-9 must use the mask issued by the ISP). This, however , is not a problematic limitation for your small network. The advantages to this situation is the greater ease and lower cost of obtaining a subnet from an ISP rather than a full Class C addr ess.
B-10 Reference Guide Manually distributing IP addr esses If you choose to manually distribute IP addresses, you must enter each computer’s address into its TCP/IP stack softwar e. Once you manually issue an address to a computer , it possesses that address until you manually r emove it.
Understanding IP Addressing B-11 ■ Avoid fragmenting your block of IP addresses. For example, tr y to use a continuous range for the static addresses you choose. The figure above shows an example of a block of IP addr esses being distributed cor rectly .
B-12 Reference Guide ■ The address range specified for addr ess-ser ved clients cannot wrap around fr om the end of the total available range back to the beginning. See below for a fur ther explanation and an example. ■ The network address issued by an ISP cannot be used as a host address.

Understanding IP Addressing B-15 The Netopia Router compares the packet’s destination IP addr ess with the routes in its IP r outing table. It begins with the route at the bottom of the list and works up until there’s a match or the r oute to the default gateway is reached.
B-16 Reference Guide Br oadcasts As mentioned earlier , binar y IP host or subnet addr esses composed entirely of ones or zer os are r eser ved for br oadcasting.
C-1 Appendix C ISDN Configuration Guide This appendix contains supplemental ISDN configuration infor mation. Definitions The following ter ms are used in this appendix: Director y number: The actual phone number associated with the ISDN line you order .
C-2 Refer ence Guide About SPIDs Depending on the type of ISDN switch protocol you use, you may be requir ed to enter SPIDs in the ISDN Line Configuration screen. Generally , SPIDs ar e used with Nor th American (United States and Canada) switch protocols.
ISDN Configuration Guide C-3 Example SPIDs If your ISDN line is controlled by a DMS-100 switch using National ISDN-1, and your director y numbers ar e given as (415)234-5678 and (415)234-5679, your SPIDs are 4152345678010 and 4152345679020. Alternately , your SPIDs can be 41523456780100 and 41523456790200.
C-4 Refer ence Guide Backup number Another use for the Optional Second Number item is for storing a backup number in case a connection cannot be made using the primar y number . For example, if calling the primar y number r etur ns a busy signal, the Netopia Router will attempt to use the secondar y number stored in Optional Second Number .

Glossary GL-1 Glossary Access Line: A communications line (e.g. cir cuit) inter connecting a frame-relay-compatible device (DTE) to a frame-r elay switch (DCE).
GL-2 Reference Guide Bandwidth: The range of frequencies, expr essed in Kilobits per second, that can pass over a given data transmission channel within a frame relay network.
GL-3 Bridge: A device that suppor ts LAN-to-LAN communications. Bridges may be equipped to provide frame r elay suppor t to the LAN devices they ser ve. A frame-relay-capable bridge encapsulates LAN frames in frame relay frames and feeds those frame r elay frames to a frame relay switch for transmission acr oss the network.
GL-4 Reference Guide Unchannelized The entire T1/E1 line is consider ed a channel, where: n The T1 line operates at speeds of 1.536 Mbps and is a signle channel consisting of 24 T1 time slots. n The E1 line operates at speeds of 1.984 Mbps and is a single channel consisting of 20 E1 time slots.
GL-5 Class A, B, and C networks: The values assigned to the first few bits in an IP network address deter mine which class designation the network has. In decimal notation, Class A network addresses range from 1.X.X.X to 126.X.X.X, Class B network addr esses range from 128.
GL-6 Reference Guide community strings: Sequences of characters that ser ve much like passwords for devices using SNMP . Dif ferent community strings may be used to allow an SNMP user to gather device infor mation or change device configurations.
GL-7 DHCP (Dynamic Host Configuration Protocol): A ser vice that lets clients on a LAN request configuration infor mation, such as IP host addresses, fr om a ser ver . DLCI (Data Link Control Identifier): A unique number assigned to a PVC end point in a frame relay network.
GL-8 Reference Guide Ethernet address: Sometimes refer red to as a har dware addr ess. A 48-bits long number assigned to ever y Ether net hardwar e device. Ethernet addr esses ar e usually expressed as 12-character hexadecimal numbers, where each hexadecimal character (0 through F) r epresents four binar y bits.
GL-9 Frame-Relay-Capable Inter face Device: A communications device that per for ms encapsulation. frame-Relay-capable r eouters and bridges are examples of inter face devices used to inter face the customer’s equipment to a frame relay network. See also Inteface Device and Encapsulation .
GL-10 Reference Guide hop count: The number of r outers a packet has gone through. If there ar e six routers between sour ce and destination nodes, the hop count for the packet will be six when it ar rives at its destination node. The maximum allowable hop count is usually 15.
GL-11 IP (Internet Protocol): A networking protocol developed for use on computer systems that use the UNIX operating system. Often used with Ethernet cabling systems. In this manual, IP is used as an umbrella ter m to cover all packets and networking operations that include the use of the Internet Pr otocol.
GL-12 Reference Guide LAN Segment: In the context of a frame r elay network suppor ting LAN-to-LAN communications, a LAN linked to another LAN by a bridge. Bridges enable two LANs to function like a single, lar ge LAN by passing data from one LAN segment to another .
GL-13 network number: A unique number for each network in an inter net. AppleT alk network numbers ar e assigned by seed routers, to which the network is directly connected.
GL-14 Reference Guide Parameter: A numerical code that contr ols an aspect of ter minal and/or network operation. Parameters control such aspects as page size, data transmission speed, and timing options. PC Card: A removable device, such as a modem or network inter face car d, approximately the size of a cr edit card.
GL-15 protocol: A set of r ules for communication, sometimes made up of several smaller sets of r ules also called pr otocols. AppleT alk is a protocol that includes the LocalT alk, EtherT alk, and T okenT alk protocols. Q.922 A (Q.922 Annex A): The inter national draft standar d that defines the str uctur e of frame relay frames.
GL-16 Reference Guide router por t: A physical or logical connection between a router and a network. Where a network only allows the use of one pr otocol, each physical connection cor responds to one logical r outer por t. An example is the Netopia ISDN Router’s LocalT alk por t.
GL-17 Statistical Multiplexing: Interleaving the data input of two or mor e devices on a single channel or access line for transmission through a frame relay network.
GL-18 Reference Guide TFTP (Trivial File T ransfer Pr otocol/Internet Protocol): A protocol used to transfer files between IP nodes. TFTP is often used to transfer fir mware and configuration infor mation from a UNIX computer acting as a TFTP ser ver to an IP networking device, such as the Netopia ISDN Router .
GL-19 zone: An arbitrar y subset of nodes within an AppleT alk inter net. Creating multiple zones makes it easier for users to locate network ser vices. The network administrator defines zones when he or she configures r outers. Isolated networks have no zones.
