Dedicated IP's

Goodmorning,

I have at home a Mikrotik router.
This router is provided by my ISP because i bought internet package which contains 5 dedicated ip’s that i can use.
Currenyly i am using 1. No matter which port I use, i always have the same IP.

As of today i wanted to use the other 4 Ip Adresses. Is there a guide where I can learn how to assign ip adresses to ports or devices?

Kind regards/

At first place it is your ISP who should provide you with such guide, because there are many ways how this can be done, but each of them has to be configured both at the IPS side and at the client router side.
