dns architecture diagram

In the last section, we use the form of text to describe the process of DNS parsing, in order to better help you understand the entire parsing process, I did a DNS domain name resolution of the step-by-step diagram, as follows: In this diagram, the 8-step parsing process allows the client to successfully access the do

DNS is currently one of the most indispensable servers on the Internet, and every day we surf the web with the help of DNS. The DNS server can resolve the domain name for us, locate the e-mail server, and locate the domain controller in the domain ... In the face of such an important server role, we need to do some in-depth research, this article tries to explore

interaction between different objects. This interaction typically manifests itself as a series of messages between different objects.Component diagrams help visualize the high-level structure of a software system.A class diagram describes an object in an application system. This description does not refer to any particular implementation of the system itself.A hierarchy diagram is used to describe the logi

finally provide services can use efficient network programming modes, memory databases, and other features to improve performance, while timely implementing the latest RFC protocol, ensure seamless connection with major recursive servers. From this we can see that the architecture of the DNS system is no longer as simple as running specific server software, but as a chain and a large system, which require

Recently, often to help friends set up Unicom 3G Internet access, often encountered some problems, the following to the Unicom 3g online set up a DNS diagram, I hope to help. Action steps are as follows: 1. Disconnect network links; 2. Open the main interface of the wireless card, select "Set"; 3. Select "Connection Settings"; 4. On the right side of the window select "Add"; 5.

The next few blog posts, bring you a simpler macro-architecture and detailed implementation of the deployment of the tutorial, no figure no JB----> The above cluster environment is briefly described as follows (2 represents the number of services or software, i.e. there are multiple identical services): 1, Nginx reverse proxy server (NGINX2, Keepalived2, yum source 1): The user all requests through the Nginx reverse proxy to distribute, and reali

Android adopts a hierarchical architecture like its operating system. From the structural diagram, Android is divided into four layers: application layer, application framework layer, system Runtime Library layer, and Linux core layer. Android Architecture 1. ApplicationsAndroid is released together with a series of core application packages, including email cli

The DNS architecture under FreeBSD-Linux Enterprise Application-Linux server application information. The following is a detailed description. Generally, a computer only needs to configure domain name resolution and does not need to run the name server daemon process on its own. However, sometimes you need to set your own name server, in this case, you need to configure the Name Server BIND (Berkeley Intern

destination IP, such as:Options {Directory "path to the named folder";Allow-transfer {203.56.100.4;176.24.99.6;}; #这样就指定下面所有的域信息可以被这两个IP获取, the rest of the IP is not.};Another way to do this is to set the ACL (Access control list) on the primary DNS server. This ACL is set at the top of the named.conf file, adding specific IP or a network side to the ACL, such as:ACL myslaves {127.0.0,1;203.56.100.1;176.24.99.1; #将上面三个ip地址, belonging to the myslaves

The architecture automatically resolves the DNS servers of different IP addresses, such as Linux Enterprise applications and Linux server applications, based on the users of China Telecom and China Netcom. The following is a detailed description. This document is based on FreeBSD and BIND platforms. Win users should be avoided. If there is no FreeBSD basic, do not. Linux or other Unix users can serve as ref
