struct utmp ( in the utmp and wtmp files) has:
ut_id which may have information about remote connections/logins - devices
ut_host has the ip of incoming remote connections/logins

The last command uses wtmp for history, who uses utmp for what is going on now.

There is also in the same struct
ut_line - it is possible this (depending on your OS) may have some information about
outgoing terminals that you can decode. IMO POSIX is fuzzy on what goes here.
I'm not sure how useful this may be.

My best suggestion - scan through the wmtp file with some C code and see how your system records data.

NAME
ssh-argv0 -- replaces the old ssh command-name as hostname handling SYNOPSIS
hostname | user@hostname [-l login_name] [command] hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name] [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command] DESCRIPTION
ssh-argv0 replaces the old ssh command-name as hostname handling. If you link to this script with a hostname then executing the link is equivalent to having executed ssh with that hostname as an argument. All other arguments are passed to ssh and will be processed normally. OPTIONS
