redirect

Redirect stands for divert or forward. The redirect function is used in transmission technology and telecommunications in various applications. Some transmission protocols have a redirect function for optimal routing.

1. In communication technology, a redirect is the forwarding of a message to the recipient(s), for example, in an e-mail service. Other recipients are not named in the messages.
2. In telecommunications, a redirect can be call forwarding or call forwarding.
3. As for the protocol world, some routing protocols have redirect algorithms that allow them to switch the optimal route. For example, in the Internet Control Message Protocol( ICMP), where a router tells a host a more effective route.
4. Redirect also exists in the web world with DNS redirect. This is the immediate or automatic redirection of a visitor to another website. Thus, visitors can be redirected from a website with a high ranking index to one with a low one. This technique is used, among other things, in hijacking, which is the hijacking of Internet addresses. The redirect function can be activated instantaneously, after a certain time or in case of an error message. The situation is different with DNS poisoning, where attackers have access to the DNS table of a server and replace a valid Internet address with a false one.
