Setting Up the IN-ADDR.ARPA Zone

Registering Your DNS Server with Root Servers

If you have a primary name server with subdomains below it and the primary
name server is not aware of the subdomains, the name server sends queries to
external name servers.
You can configure your primary name server to not forward queries for
specified internal subdomains to external name servers. Instead, the primary
name server sends a negative response to any queries for the internal
subdomains.
Just as the data in your name server provides mapping of names to Internet
addresses, the IN-ADDR.ARPA zone provides mapping of addresses to
names. However, in the structure of the IN-ADDR.ARPA zone, the IP address
appears in reverse. For example, an IP address of 100.20.30.4 in the san-jose.
novell.com domain would be 4.30.20.100.in-addr.arpa in the IN-
ADDR.ARPA subdomain.
If you plan to operate a primary DNS name server, you must register your
name server with your parent domain. Not all your name servers need to be
registered, but we recommend registering one-third to one-half of your name
servers (up to a maximum of 10) with the parent domain. These servers are
queried by servers outside your domain. The remaining name servers are
queried only by hosts within your domain that are configured to query them.
If you provide DNS service for other domains and provide an authoritative
name server for those domains, you must also register those domains.
To register a domain (and subdomain), you must contact the network
administrators of the parent domain (com, for example) and the in-addr.arpa
domain. Provide the administrators with the name of the domain name server
and the name of the domain and any subdomains for which it is authoritative.
If you are setting up a new domain, you also need to provide the IP address of
any server you want to register.
InterNIC is the organization that registers domain names for the ROOT, com,
org, net, edu, and gov domains. To obtain the form for domain registration
