6.14 DNS Configuration

6.14.1 DNS Summerization
DNS is Domain Name System for short，DNS is a distributing database using in TCP/IP application.. It
can provide the translation of host name and IP address, some information about email and hosts.
The name DNS is used in the TCP/IP network, such as Internet，and it orientates hosts and service
according to friendly name. When the DNS name is input, the system can translate it into relative
information such as IP address.
In DNS system, DNS Resolver equals to a client of DNS Server. The application can get relative
information by accessing DNS Server. The base of this information is: getting the IP address according
to a host name or getting the host name according to a IP address.
Dynamic DNS Resolver is used in the condition of dynamic IP addresses. Dynamic DNS Resolver can
register the information about Host/address to DNS Server auotly， when the IP address changes, it can
send updating message to DNS Server and the DNS Server will update its database.
1. DNS Application
DNS has abroad application：
♦ Provide translating host name to IP address for ping、telnet and traceroute.
♦ Provide translating IP address to host name for telnet. When traceroute gets each IP address, it
can get the name of the address.
♦ When IP address of client changes, it can update the address in primary server.
2. DNS Term
DNS Resource Record（RR）
information, which may be empty. The set of resource information associated with a particular name
is composed of separate resource records (RRs). The order of RRs in a set is not significant, and
need not be preserved by name servers, resolvers, or other parts of the DNS.
When we talk about a specific RR, we assume it has the following:
owner
type
This memo uses the following types:
A
CNAME
HINFO
MX
NS
PTR
Access-list name
which is the domain name where the RR is found.
which is an encoded 16 bit value that specifies the type
of the resource in this resource record. Types refer to
abstract resources.
a host address
identifies the canonical name of analias
identifies the CPU and OS used by a host
identifies a mail exchange for the domain. See [RFC-974 for details.
the authoritative name server for the domain.
a pointer to another part of the domain name space
