We mean, If someone has a Dynamic IP it means that they don't keep the same IP all the time. One time it may be 173.24.56.127 other times it could be 173.24.43.324.
With a Static IP they will keep the same IP all the time. So if someone has 173.24.22.332, They will have that IP until they switch ISP ( Internet Service Provider). If the account is registered to IP and they have a Dynamic IP. They will never be able to keep their account. They will loose all data because they don't keep their IP.
Only this system would work for people with Static IP's. People don't usually have a Static IP. That's why you see so many SA-MP servers that always have different IP's, The person hosting it (Usually home hosted) has to tell everyone about their new IP.

So lets say I join your server. (I do have a Static IP) I will do my business in your server then /q. If I had a Static IP I would be able to join with the same name and play with my stats. If I had a Dynamic IP and tried to connect, I would loose all my stats and the name. I would have to create a new account everytime I got a new IP.

You see what I mean?
