A series of courses in Windows Network Services Architecture (ii) Deployment and configuration of DNS servers

Experimental background:

In the early days of Internet network development, because the IP address is not easy to remember, the way of network interconnection mainly through the purchase of Hosts file domain name analysis, at that time, the computer network interconnection is not a lot. Subsequently, with the continuous development and popularization of computer network, more and more computers use the domain name, but the powerful hosts file can no longer meet the needs of the modern network, DNS (domain Name System, domain name systems) has emerged.

DNS relative to the hosts file, a powerful improvement, mainly in a tiered structure for deployment, including: root domain, top-level domain (including organization domain, country domain or area, reverse domain), level two domain and host name. The hierarchy of the domain name space resembles an inverted tree, where the root is the highest level, the bough at the next level, and the leaves at the lowest level. In this way, the huge amount of information can be divided into many smaller parts according to the hierarchy structure, and each part is stored on different computers to form the characteristics of hierarchy and distribution. On the one hand, it solves the unity of information, on the other hand, the information data distributed widely, will not form the bottleneck, is advantageous to improve the access efficiency.

Experimental purposes:

1. Learn to install DNS server

2, will create a positive and negative lookup zone on the DNS server

3. New resource records (including hosts, aliases, and SRV records)

4. Forwarders and root hints will be configured

5, master DNS zone transfer

6, configure DNS settings for the client

7. Understand the relationship between DNS server and AD
