Hello Karthi,
AFAIK the floating license file should be locked to the same locking ID for all the seats (e.g. server MAC or Disc Volume ID)
TCP port and server name/IP address is fully configurable and it's typically common for all the seats and you can change them any time.
Your license.dat on the server side typically contains common SERVER/DAEMON lines and merged features from all the floating license.dat files (locked to same ID)
SERVER tokyo 17007ea8 1700
VENDOR metrowks

FEATURE f1 xyzd 1.000 01-jan-99 5 16BE40E1DAEEEDA8798D ""

Hope it helps.
