1.1 DNS Overview

Domain Name System (DNS) is a mechanism used for TCP/IP applications to provide

domain name-to-IP address translation. With DNS, you can use memorizable and

meaningful domain names in some applications and let the DNS server resolve it into

correct IP addresses.

There are two types of DNS services, static and dynamic. Each time the DNS server

receives a name query, it checks its static DNS database before looking up the dynamic

DNS database. Reduction of the searching time in the dynamic DNS database would

increase efficiency. Some frequently used addresses can be put in the static DNS

Currently, S5600 series Ethernet switches support both static and dynamic DNS

The static domain name resolution means manually setting up mappings between

domain names and IP addresses. IP addresses of the corresponding domain names

can be found in the static domain name resolution table for applications, such as Telnet.
