ES-4000V2 has the function of resolving domain name which enables user to set up a DNS server on user's own without any expanded cost. While setting up DNS, please direct the registered domain name to the ES-4000V2's IP address beforehand. (All types of domain name need to be resolved by a DNS server, whether it's an address type or a mail exchanger one. ) In this chapter, it will walk you through DNS Setting with detailed utilization description. DNS Setting Domain Name: It refers to a website address that user applies from ISP. An IP address like 198. 68. 20. 78 is not easy for computer users memorizing, therefore, the domain names intend to replace the figure-pattern addresses with meaningful letter-pattern ones, such as www. airlive. com The website address is composed of two parts, host name and domain name. Web browsers type address like www. yahoo. com to log onto its webpage while it's physical IP is 66. 218. 71. 84. And DNS server is the one who plays the role of mapped domain name and physical IP address together. Enable DNS Zone Allows users to activate DNS and set up the address mapping policies. (Figure 5-1) Figure 5-1 DNS setting 50 DNS Configuration Foremost, register the IP address on IDNs (International Domain Names) official website. Supposed that IP segment are given as follow: 61. 11. 11. 10 ~ 61. 11. 11. 14 211. 22. 22. 18 ~ 211. 22. 22. 30 3. Set up primary host name server as: Host Name: dns1. airlive. com IP Address: 61 . 11 . 11 . 11 Set up secondary host name server as: Host Name: dns2. airlive. com IP Address: 211 . 22 . 2 2 . 22 Select Type: It is divided into three types, namely Address (A), Canonical NAME (CNAME) and Mail eXchanger (MX). 51 5. 1 A (Address) This is used to map up IP addresses and domain names. (Table 5-1) Domain Names host1. airlive. com host2. airlive. com host2. airlive. com Type A A A IP Address 61. 11. 11. 12 61. 11. 11. 13 211. 22. 22. 23 Table 5-1 Mapping table of domain name and IP address "A" represents IP address. The table above indicates that host2 is assigned to two IP addresses, so it lists out two entries corresponding to host2. Every DNS inquiry might have one responding address or above and is sorted in address-sorting style or round-robin style. 52 5. 2 CNAME (Canonical NAME) This type allows mapped domain names to have one website address or above available for web browsers at the same time. Type CNAME is capable of mapping a type "A" mapped domain name, yet it is not recommended mapping a type "CNAME" domain name. (Table 5-2) Domain Name host23. airlive. com host5. airlive. com Type A CNAME IP Address 61. 11. 11. 14 host23. airlive. com Table 5-2 Mapping table of CNAME The table above indicates that host5. airlive. com (Alias) is mapping to host23. airlive. com (domain name). Thus, pinging host5. airlive. com under DOS mode will have the result of 61. 11. 11. 14. 53 5. 3 MX (eXchanger) It served as a mail agent for DNS server and a window to the outside for mail services. In spite of ailing for mail server replacement, the mail server could be back to function in no time just by modifying the DNS address. Ex. 1: "MX", also known as "Mail eXchanger", is a type of resource record especially designed for mail service. (Table 5-3) Domain Name host25. airlive. com mail. airlive. com Type A MX IP Address 211. 22. 22. 24 host25. airlive. com Table 5-3 Mapping table of mail eXchanger Under DOS mode, type nslookup -type=MX mail. airlive. com, you will find that mail. airlive. com is mapping to host25. airlive. com (the mail eXchanger) and its IP address 211. [. . . ] MTA (Mail Transfer Agent): Outgoing and incoming mails are all done by MTA. As long as user has a account under MTA, then the user will be able to receive mail. On condition that the user has the authority, he will be able to send out mails. User can retrieve and view mails that saved on the mail server. Usually, MTA refers to a mail server. [. . . ]
