# 4.3. DNS

Domain Name

  Specify the domain name for your machine. As with DNS Addresses it is restored to the original specified in `/etc/resolv.conf` when the connection goes down. If it is left blank no changes are made to the domain name specified in `/etc/resolv.conf`

DNS Servers

  Add the Domain Name servers assigned to you by your ISP. You must specify at least a Domain Name server for your OS to be able to resolve human readable IP addresses such as ftp.kde.org. The DNS server addresses supplied must be in numeric form, e.g 128.231.231.233. The addresses will be added at runtime to `/etc/resolv.config`.

Disable existing DNS Servers during Connection

  Select this option if you want kppp to disable already existing nameserver entries in `/etc/resolv.conf` during connection.
