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