Don't sure that I really understand your question.
If only IP addresses change then you can use simple DNS server to
store domain -> ip mapping (both domain names and IPs can be private,
i.e. device1.localdomain. and 10.0.1.5). In fact, it is exactly the
purpose of DNS as opposed to hosts files.
If some other config info has to be changable (e.g., ssh ports) then
you can share your config using configuration file which could be
updated (e.g., you can download it from some internal http server on
each boot, or use a file on some SMB share). The name of the
configuration file is different for each ssh client...
