Using this, you 20can make the curl requests(s) use a specified address and prevent the 21otherwise normally resolved address to be used. Consider it a sort of 22/etc/hosts alternative provided on the command line. The port number should be 23the number used for the specific protocol the host is used for. It means 24you need several entries if you want to provide address for the same host but 25different ports. 26 27By specifying `*` as host you can tell curl to resolve any host and specific 28port pair to the specified address. Wildcard is resolved last so any --resolve 29with a specific host and port is used first. 30 31The provided address set by this option is used even if --ipv4 or --ipv6 is 32set to make curl use another IP version. 33 34By prefixing the host with a '+' you can make the entry time out after curl's 35default timeout (1 minute). Note that this only makes sense for long running 36parallel transfers with a lot of files. In such cases, if this option is used 37curl tries to resolve the host as it normally would once the timeout has 38expired. 39 40Support for providing the IP address within [brackets] was added in 7.57.0. 41 42Support for providing multiple IP addresses per entry was added in 7.59.0. 43 44Support for resolving with wildcard was added in 7.64.0. 45 46Support for the '+' prefix was added in 7.75.0. 47
