Well, maybe you could use a simple trick. For address resolution, it
doesn't matter whether a host name has a trailing dot. "host", "host.",
"host..", etc resolve all to the same IP address.

For Tramp these are different strings, so it can distinguish. Maybe you try

As I wrote the other message, it isn't possible. Tramp wouldn't know how
to handle "/ssh:root@master1:".
