| 20 | <para>If the system is going to be connected to the Internet, it will
|
|---|
| 21 | need some means of Domain Name Service (DNS) name resolution to
|
|---|
| 22 | resolve Internet domain names to IP addresses, and vice versa. This is
|
|---|
| 23 | best achieved by placing the IP address of the DNS server, available
|
|---|
| 24 | from the ISP or network administrator, into
|
|---|
| [1b896d0] | 25 | <filename>/etc/resolv.conf</filename>. If at least one of your network
|
|---|
| [82c4aa0] | 26 | interfaces is going to be configured by DHCP then you may not need to
|
|---|
| 27 | create this file. By default DHCPCD will overwrite this file when it gets
|
|---|
| 28 | a new lease from the DHCP server. If you wish to manually configure your
|
|---|
| 29 | network interfaces or manually set your DNS using DHCP then create the
|
|---|
| 30 | file by running the following:</para>

|

| 47 | with the IP address of the DNS most appropriate for the setup. There will
|
|---|
| 48 | often be more than one entry (requirements demand secondary servers for
|
|---|
| 49 | fallback capability). If you only need or want one DNS server, remove the
|
|---|
| 50 | second <emphasis>nameserver</emphasis> line from the file. The IP address
|
