Provide a custom address for a specific host and port pair. Using this, you can make the curl requests(s) use a specified address and prevent the otherwise normally resolved address to be used. Con-
sider 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 will be used for. It means you need several entries
if you want to provide address for the same host but different ports.
The provided address set by this option will be used even if -4, --ipv4 or -6, --ipv6 is set to make curl use another IP version.
This option can be used many times to add many host names to resolve.
Added in 7.21.3.
