Checking Your Name Server Getting Started Guide 115 2. Check the order of resolving Internet domain names by reviewing the Information source field. The normal order is host, nis, dns. This means that first your local hosts file (/etc/hosts) is searched to resolve the domain name to an IP address, then the NIS database is checked, and lastly the DNS server is accessed via your network connection. 3. If you want to change the order of this process, choose the button labeled host, nis, dns and rearrange the order. 4. Check the address of your DNS server as shown in the DNS server field. 5. If you need to update the DNS server address or add another DNS server, click on the button that contains the address. A dialog box opens where you can define DNS servers by their IP addresses. (See Figure 62.) FIGURE 62.  You can define DNS servers by entering their IP addresses in this dialog box. NOTE: It’s a good idea to have at least two DNS servers listed in this dialog box. If one DNS server is unavailable for some reason, your system can query the other DNS server to resolve domain names. 6. Add additional servers or edit the selected DNS server address by selecting items on the Edit menu.
