21.6.2 For More information
The following sources are available for further information about SLP:
RFC 2608, 2609, 2610 RFC 2608 generally deals with the definition of SLP.
RFC 2609 deals with the syntax of the service URLs used in greater
detail and RFC 2610 deals with DHCP via SLP.

This directory contains all available documentation on SLP, including
a README.SuSE containing the SUSE LINUX details, the RFCs
mentioned above, and two introductory HTML documents. Pro-
grammers who want to use the SLP functions should install the
openslp-devel package to consult its supplied Programmers Guide.
21.7 DNS — Domain Name System
DNS (domain name system) is needed to resolve the domain and host
names into IP addresses. In this way, the IP address 192.168.0.0 is as-
signed to the host name earth, for example. Before setting up your own
name server, read the general information about DNS in Section 21.1.3 on
page 421. The configuration examples below are only valid for BIND 9.
21.7.1 Starting the Name Server BIND
On a SUSE LINUX system, the name server BIND (Berkeley Internet name
domain) comes preconfigured so it can be started right after installation
without any problem. If you already have a functioning Internet connection
and have entered 127.0.0.1 as the name server address for localhost
in /etc/resolv.conf, you normally already have a working name res-
olution without needing to know the DNS of the provider. BIND carries
out the name resolution via the root name server, a notably slower process.
Normally, the DNS of the provider should be entered with its IP address in
the configuration file /etc/named.conf under forwarders to ensure
effective and secure name resolution. If this works so far, the name server
runs as a pure caching-only name server. Only when you configure its own
zones will it become a proper DNS. A simple example of this is included
