One of the best features of Ethernet is that it enables a group of interfaces on a specific network to listen for broadcasts being transmitted to a specific group address, known as a multicast address. This allows a single host to originate a packet that is to be read by a number of different hosts, without having to retransmit the packet multiple times. In addition, each interface listens on its normal MAC address as well as on the multicast address.

A MAC address is a hexadecimal number that is set in the factory by every network interface manufacturer. It contains elements that allow an interface to be distinguished from those manufactured by other companies, and also allows individual interfaces from the same manufacturer to be distinguishable. It is possible, with SPARC systems, to set the MAC address manually in the PROM. However, this is generally not advisable, except in systems with multiple interfaces, where they might have the same MAC address by default. The format of the MAC address is usually a set of hexadecimal numbers delimited by colons. The MAC address 11:22:33:44:55:AA is one example. The initial three bytes identify a specific manufacturer the list of manufacturers and their codes can be downloaded from ftp://ftp.lcs.mit.edu/pub/map/ethernet-codes. In order to support IP and higher-level transport and application protocols, a mapping must be made between the MAC address and the IP address. This is achieved by the Address Resolution Protocol (ARP) and Reverse Address Resolution Protocol (RARP). The hardware address, otherwise known as the MAC address, is used to distinguish hosts at the link level. This is mapped to an IP address at the Network level, by using ARP and RARP.

The basic element of IP version 4 (IPv4) is the IP address, which is a 32-bit number (4 bytes) that uniquely identifies network interfaces on the Internet. For single-homed hosts, which have only one network interface, the IP address identifies the host. However, for multihomed hosts, which have multiple network interfaces, the IP address does not uniquely identify the host. Even the domain name assigned to a multihost can be different, depending on which network the interface is connected to. For example, a router is a host that contains at least two interfaces, since it supports the passing of data between networks. The IP address is usually specified in dotted decimal notation, where each of the bytes is displayed as an integer separated by a dot. An example IP address is 192.205.76.123, which is based on a Class C network. There are five classes of network defined by IP (A, B, C, D, E), although only three of these (A, B, and C) are actually used for the identification of hosts. Network classes can be identified by a discrete range of values; thus, if an address lies within a specific range, it can be identified as belonging to a network of a specific class. The following ranges are defined by IP: Class A Class B Class C Class D Class E 0.0.0.0 127.255.255.255 128.0.0.0 191.255.255.255 192.0.0.0 223.255.255.255 224.0.0.0 239.255.255.255 240.0.0.0 247.255.255.255

for example, the network 10.0.0.0 is reserved for private use, and is commonly used to define IP addresses for internal networks. This is a security feature, since 10.0.0.0 addresses are not resolvable from the Internet. In addition, the 127.0.0.0 addresses are used to refer to the localhost, with the most commonly used value being 127.0.0.1. Subnets allow large networks to be divided into smaller, logical networks, by using a subnet mask. For class A networks, the mask is 255.0.0.0; for class B networks, the mask is 255.255.0.0; and for class C networks, the mask is 255.255.255.0. Solaris 10 provides complete support for IPv6 and IPSec, discussed in 25. These innovations are designed to increase the capacity of the Internet, and secure packets transmitted by using transport protocols. The IP layer sits between the Network ( Ethernet ) and Transport layers in the stack. Thus, it provides the interface between the underlying physical transport and the logical transport used by applications. It manages the mapping between hardware (MAC) addresses and software addresses for network interfaces. To connect a LAN to the Internet, it is necessary to obtain an IP network number from the InterNIC. However, since most Solaris software uses TCP/IP for network operations, even when not connected to the Internet, it is necessary to become familiar with IP, including its configuration and its major operational issues. IP carries out the following functions in the stack: Addressing Mapping hardware addresses to software addresses
Routing Finding a path to transmit a packet from a source network interface to a destination network interface Formatting Inserting specific types of data into a packet to ensure that it reaches its destination Fragmentation Dividing packets into fragments in situations where a packet is too large to be transmitted using the underlying medium IP relies on three other protocols for its operation: ARP ensures that datagrams are sent to the correct destination network interface from a source network interface by mapping IP addresses to hardware addresses. RARP is responsible for mapping hardware addresses to IP addresses. The Internet Control Message Protocol (ICMP) is involved with the identification and management of network errors, which result from packets being dropped, from physical disconnection of intermediate and destination routers, and from a redirection directive issued by an intermediate or destination router. Note that the ping command is typically used as the interface to check for errors on the network. The key data structure used by IP is the datagram. Details about the datagram are recorded in the packet s header, including the addresses of the source and destination hosts, the size of the datagram, and the order in which datagrams are to be transmitted or received. The structure of the IP datagram is shown in Figure 21-7. The Version is an integer that defines the current IP version (i.e., 4). The Header Length specifies the size, in bytes, of the packet header generally, the header is 20 bytes in length, since IPv4 options are not often used. The Type of Service specifies, in 8 bits, what type of data is being handled. This allows packets to be designated as
