Is it possible to use a single user LAN address (/24) exclusively for one business system (e.g., FLEX only)?

Is it possible to use a single user LAN address (/24) exclusively for one business system (e.g., FLEX only)?
Category : 

Answer

Effective December 1, 2023, the allocation method for address ranges for each business system has been discontinued.
Thus, it is possible to use a single user LAN address (/24) exclusively for one business system.
*Please note that within the 24-bit mask, "x.x.x.0-3" and "x.x.x.255" are not allowed to use as host addresses for connecting to any business systems.
