--resolve <host:port:address>
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. 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 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.

しかし、与えられた制限のため(「同じホストで異なるポートにアドレスを提供する場合、いくつかのエントリが必要です」)、両方を同時に変換できる別の新しいオプションを検討します。
--connect-to <HOST1:PORT1:HOST2:PORT2>
For a request to the given HOST:PORT pair, connect to
CONNECT-TO-HOST:CONNECT-TO-PORT instead. This option is suitable
to direct requests at a specific server, e.g. at a specific cluster
node in a cluster of servers. This option is only used to establish
the network connection. It does NOT affect the hostname/port that
is used for TLS/SSL (e.g. SNI, certificate verification) or for
the application protocols. "host" and "port" may be the empty string,
meaning "any host/port". "connect-to-host" and "connect-to-port"
may also be the empty string, meaning "use the request's original host/port".
This option can be used many times to add many connect rules.
See also --resolve and -H, --header.
