akamai dns servers

DNS (Domain Name Server) is a huge distributed database that provides a specified Domain information through the Domain Name Server for Domain Name resolution. The Domain Name Server is responsible for converting the Domain Name to an IP address. It is impossible to put all Domain Name Information in the Internet on the same computer. Therefore, the DNS system uses a tree structure to store domain name info

responsible for maintaining all data in this subdomain. they can change data freely, and even divide the subdomains they manage into more subdomains and reallocate them. the parent domain only contains pointers pointing to these subdomains, so it references queries there. 1.2 A Domain name server is called a Domain name server ). generally, a Domain Name Server has complete information about some domain name spaces (called zone zones. the domain name server can have multiple zones for authoriza

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

Shanghai ms (Headquarters) has more than 800 nodes. subsidiaries, offices, and partners all over the world are remotely connected to the headquarters, what is the responsibility of the company as its in charge of the network! Details determine success or failure: network devices (such as routers, switches, firewalls), servers ...... Next to the PC, and even an OE (or outlook) configuration, backup, mail import, export, and so on all have very detailed

the proxy server, the proxy server directly sends the buffered content to the user. If there is no buffer, a request is sent to the WEB server first to retrieve the data, and then the local cache is sent to the user. This method reduces the number of requests sent to the WEB server and the load on the WEB server. Ii. System Architecture 1. Principles DNS round robin technology is used to distribute requests from clients to one of the Squid reverse pr

NFS is a Web FileSystem network file system developed by Sun that is equivalent to a win mapped network drive that can "mount" a directory on an NFS server to a local directory on a local machine.The NFS configuration file is:/etc/exports [' eksp2rt] output, exportVi/etc/exports:/home/dir_to_exported clients_nfs (rw, sync and other sharing options)In fact, the configuration and use of NFS shares is the same as the idea and procedure of using smbclient or mount to make Linux share Windows shared
