One day, a q visited Company A and handed him A business card containing information such as his "hacker murder club" and phone number, company A thought it was necessary to make A simple investigation into the origins of Q, so he called the Teleco

B. Click here to add two DNS servers, such as ns1.abc.com and ns2.abc.com. Fill in the IP address of the server where winmydns is installed. If you do not have two machines or two fixed IP addresses, you can write an IP address for NS2.
C. Enter your dnsdomain name on the h

Always want to find a free unlimited frequency domain name query interface, online find for a long time did not find, finally simply write a domain name lookup interface, the principle is directly with PHP to find the domain name whois information, but directly find whois too slow, you want to first find the domain name of the NS record, If there is an NS record, this domain name is already registered, so theoretically should be faster, this idea is right?
Now I use PHP dns_get_record query DNS
The temporary understanding is (and does not know that):
DI is the IOC implemented with reflection
Service locator is a combination of Registrar mode and Factory mode (Factory mode with memory function)
Try to use PHP as a small example to illustrate, thank you

A typical proxy server inserts a P-called-party-id header domain when routing INVITE requests to a destination. The header field is filled in with the request-uri of the PORXY received request. UAS identifies from several registered aors which AOR the session invitation is sent to.Users of the 3GPP IMS can obtain one or more SIP URIs (AOR) that identify the user. For example: A user can obtain a business SIP URI and a personal SIP URI. One application case is that the user can make the business

The domain name resolution (http://www.jbxue.com/tags/yumingjiexi.html) to the specified IP address, is very simple:Log on to the domain name management address, and then make A record to your space ip address, but you need to check the status of your domain name, if the domain name status is OK, just take the next step. The specific tutorial will be completed after the domain name management.

Each Web application has multiple object combinations and collaboration to accomplish the task. These objects need to be instantiated and connected together to work. In ANGULARJS applications, these objects are instantiated and assembled automatically by the Injector injector service. In the case of the injector injector, it can create two types of objects: service services and special objects. The special object is the API that complies with the specified angular framework. These objects can be
