Help regarding the madpack 2 server's

hi i have this problem of getting my map resetted in madpack 2 on my minimap because of the dyn ip. because of the dyn ip. the server makes new maps everytime i play madpack 2. which makes me mad that im losing my progress. is their any way to fix this? like the dyn ip is pretty much ruining the game. because of that. everytime the server stops. and starts again i get a brand new map. and my waypoints and such is gone.

the other ip is the one i use right? for example. sythrilkz.aternos.me i use it but it still reset's ...

it does for me . thats what the problem is. like if i log in with sythrilkz.aternos.me everytime. it records the dyn ip in the map mp folder ...
