In the previous blog, we introduced the DNS server architecture, from which we learned that if we want to register a domain name, then we must go through the top-level domain name server or its subordinate domain name server for our application of the domain name to delegate, the right to resolve to our DNS server, In this way we can obtain the right to resolve the requested domain name. In this article we

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 domain name of www.163.com, but in practical applications, the process is usually very rapid

ThroughHostname, the process of eventually getting the IP address for that hostname is called Domain name resolution (or hostname resolution). The DNS protocol runs onUd

1. Because of the design requirements of Exchange 2010, we need to add the relevant DNS records and add the following records: Automatic discovery is an automatic Outlook feature provided by Exchange 2007 and above, and if your Outlook is above the 2007 SP2 version, you can enjoy the flexibility that automatic discovery brings to your machine. So we add a Autodiscover record here: Autodiscover.xxx.xxx CAS Server1 Autodiscover.xxx.xxx CAS Server2 B
