233Second, <e>if</e> you need a domainname, set it in <path>/etc/conf.d/net</path>.
234You only need a domain if your ISP or network administrator says so, or if you
235have a DNS server but not a DHCP server. You don't need to worry about DNS or
236domainnames if your networking is setup for DHCP.

253If you have a NIS domain (if you don't know what that is, then you don't have
