So,
some years ago I helped a friend to install DSM 6.x on a HP N54L Microserver, based on Jun's 1.0x bootloader,
and I left it running with DHCP based IP for the ease of moving it between my and his "homelabs".
Down the road, he was giving it a fixed IP, outside his local DHCP scope, all OK.
But, when moving to a different location it was stored for a while.
New location, new ISP and new router with a different IP range, now its getting complicated...
When it was time to hook it up, no connection (naturally).
And the tricky part is, he has totally forgotten both the IP and the IP range he used to have.
The question:
How can we find, and connect to the HP so the old fixed IP can be changed to reflect his new IP range?
