IP multicast transfers data to some hosts. One or more hosts are represented by one IP address. Multicast transfers data to all hosts in the best way like normal IP Address Transmission. The group members are dynamic. Members can join or leave a group at any time. The group size and position are not limited. A
How does Godaddy add an independent IP address to the host account? After purchasing an independent IP address, Godaddy will not automatically add it to your host account. You need to set it yourself.

People are increasingly interested in using SSL and name-based virtual hosts. Some people think this is impossible, but in Apache, You can implement virtual hosts through IP-based virtual hosts. In this article, John Liao and Jim Miles will introduce you to specific practices.In the previous developerWorks article "Secure remote data access for Domino ?" We discussed how to use Apache Web servers to Solve enterprise problems in a budget-saving manner.

In a Kering host environment, typically all hosts in an office network do not have a public IP address, but they are able to access the Internet through a router (gateway) device with an IP address, which requires only NAT and forwarding capabilities. A device with such a function can, of course, be replaced by a single computer.The following is the simplest mode
Nginx (pronounced with engine x) is a lightweight Web server/reverse proxy server and e-mail (IMAP/POP3) proxy server that is released under a bsd-like protocol. It is characterized by the possession of less memory, concurrency is strong, in fact, nginx concurrency is actually in the same type of Web server performance better. Nginx as with Apache httpd, Nginx also provides IP-based, port-based and domain name mode to configure the virtual
Brief introductionVirtual host refers to a certain amount of disk space on the network server, the administrator can take advantage of this part of the space, put the site and application components, provide the necessary data storage and transmission functions. A virtual host is one that divides a physical server running on the Internet into multiple "virtual" servers.AdvantagesLow price. Compared to the p
A virtual host can coexist with multiple sites. When the site has little traffic, multiple sites can run on one physical host to save resources (IP addresses and physical hosts.
