5 | 5 | * '''Your ISP's DNS servers redirect lookups of nonexistent host names to a search page.''' Some ISPs have decided that instead of returning the correct error code when a hostname does not exist, they will pretend that it does and say that its IP address is one that actually belongs to a web server they run. The idea is to be convenient for users, since it gives them a search page when they try to visit a nonexistent site in a browser. However, as well as violating the relevant Internet standards, this behaviour breaks many programs (such as MacPorts) that need to know whether a hostname exists or not. |
