after checking openssh documentation and source I found that `openssh don't have any token for controlpath expression where ip address can be specified.` In case if you want to use it you can use my repo which I edited source of openssh and added the token %x for ip address resolving.
Now ControlPath becomes:
ControlPath /home/user/.ssh/sockets/ssh_mux_%x_%p_%r
ControlPath supported tokens:
"l", thishost,
"n", host_arg, "n", host_arg,
"p", portstr, "p", portstr,
"x", hostip,
"r", options.user, "r", options.user,
"u", pw->pw_name, "u", pw->pw_name,
"i", uidstr, "i", uidstr,
"h", host,
