customer. Because I have created the root domain and net domain on the DNS server in the LAN, when the DNS server receives a domain name that cannot be resolved, it will mistakenly think that it is the root domain server, the real root domain server in the Internet cannot be found, so the client cannot access the website using the domain name. Solution First, delete the root domain, net domain, and rt

For details about dns settings in linux-Linux Enterprise Application-Linux server application, see the following. ① Introduction DNS is the Domain Name System, which can convert a Domain Name such as www.21php.com to an IP address such as 211.152.50.35. If there is no DNS, When you browse the website 21php.com, you must use numbers that are so hard to remember as

DNS server within the LAN, so when a DNS server receives a domain name that cannot be resolved, it incorrectly considers itself to be the root domain server, and cannot find the real root domain server in the Internet, so there is a problem that the client cannot use the domain name to access the Web site. Solutions First remove the root domain, net domain, and rtj.net domain from the

First, the basic principleHTML5 introduced the cross-document communication API (Cross-document messaging) in order to resolve cross-domain. This API adds a new Window.postmessage method to the Window object, allowing cross-window communication regardless of whether the two windows are of the same origin. This feature is supported by Internet Explorer 8+, Chrome,firefox, opera, and Safari.Second, the test steps1. Create a.htmlDOCTYPE HTML>HTMLLang= "en">Head> MetaCharSet= "UTF-8"> title>Wi

The implementation of a hash table is often called hashing. Hashing is a technique used to perform insertions, deletions, and lookups of constant average time. However, tree operations that require ordering of element information are not supported. So for example, findmax,findmin and the sort traversal of these operations are not supported by hashing.If an element is hashed with an inserted element (such as an array ordinal of a hash list, and many elements are inserted into the same sequence nu

How to implement centralized DNS resolution To meet the requirements, many organizations and individuals have created multiple different Web sites. To save site construction costs as much as possible, these sites generally use one machine and multiple sites technology, that is, the virtual host technology we mentioned at ordinary times. This technology is used to run multiple independent domain name Web sites simultaneously on a server with only one p

1. What is DNS? (Domain Name System) domain name system. In fact, the functions implemented by DNS are very simple and effective, so that users do not need to remember the IP addresses that frequently access the server, you can directly access the IP addresses of numeric strings in a format similar to that in pinyin. Suppose we use 61.120.155.14 (for example) to use these numbers to access the Web server.
