The /etc/networks file holds the domain names and IP addresses of networks you are connected to, not the domain names of particular computers. Networks have shortened IP addresses. Depending on the type of network, they use one, two, or three numbers for their IP addresses. You also have your localhost network IP address 127.0.0.0. This is the network address used for the loopback device. The IP addresses are entered, followed by the network domain names. Recall that an IP address consists of a network part and a host part. The network part is the network address you find in the networks file. You always have an entry in this file for the network portion of your computer's IP address. This is the network address of the network to which your computer is connected. A sample /etc/networks file is shown here with an entry for the mytrek.com network. /etc/networks

The /etc/services file lists network services available on your system, such as FTP and telnet, and associates each with a particular port. Here, you can find out what port your Web server is checking or what port is used for your FTP server. You can give a service an alias, which you specify after the port number. You can then reference the service using the alias.

Domain Name Service (DNS)
Each computer connected to a TCP/IP network, such as the Internet, is identified by its own IP address. IP addresses are difficult to remember, so a domain name version of each IP address is also used to identify a host. As described in 10, a domain name consists of two parts, the hostname and the domain. The hostname is the computer's specific name, and the domain identifies the network of which the computer is a part. The domains used for the United States usually have extensions that identify the type of host. For example, .edu is used for educational institutions and .com is used for businesses. International domains usually have extensions that indicate the country they are located in, such as .de for Germany or .au for Australia. The combination of a hostname, domain, and extension forms a unique name by which a computer can be referenced. The domain can, in turn, be split into further subdomains. As you know, a computer on a network can still only be identified by its IP address, even if it has a hostname. You can use a hostname to reference a computer on a network, but this involves using the hostname to look up the corresponding IP address in a database. The network then uses the IP address, not the hostname, to access the computer. Before the advent of large TCP/IP networks, such as the Internet, it was feasible for each computer on a network to maintain a file with a list of all the hostnames and IP addresses of the computers connected on its network. Whenever a hostname was used, it was looked up in this file and the corresponding IP address was located. You can still do this on your own system for remote systems you access frequently. As networks became larger, it became impractical and, in the case of the Internet, impossible for each computer to maintain its own list of all the domain names and IP addresses. To provide the service of translating domain addresses to IP addresses, databases of domain names were developed and placed on their own servers. To find the IP address of a domain name, you send a query to a name server, which then looks up the IP address for you and sends it back. In a large network, several name servers can cover different parts of the network. If a name server cannot find a particular IP address, it sends the query on to another name server that is more likely to have it. If you are administering a network and you need to set up a name server for it, you can configure a Linux system to operate as a name server. To do so, you must start up a name server daemon and then wait for domain name queries. A name server makes use of several configuration files that enable it to answer requests. The name server software used on Linux systems is the Berkeley Internet Name Domain (BIND) server distributed by the Internet Software Consortium (www.isc.org). 18 describes the process of setting up a domain name server in detail.
Name servers are queried by resolvers. These are programs specially designed to obtain addresses from name servers. To use domain names on your system, you must configure your own resolver. Your local resolver is configured with your /etc/host.conf and /etc/resolv.conf files. You can use /etc/nsswitch in place of /etc/host.conf.
