it redirects to a new server page where all the ranking is eareased ?

You'll need to provide information that will allow someone to assist you.

For example,

1. The steps you took
2. What happened
3. Links to server page(s)

We moved our Servers.
From one ip to another.
2. So i wanted to add a DNS to update the ip
3. old : http://www.gametracker.com/server_info/altislife.mscrew.de:2302/ new : http://www.gametracker.com/server_info/85.25.155.73:2302/

What is the IP of the old page?

78.111.76.10:2302

Have you received an email about a "conflict"?

I would suggest you claim the new page at:

http://www.gametracker.com/server_info/85.25.155.73:2302/
or
http://www.gametracker.com/server_info/altislife.mscrew.de:2302/

I suspect the new IP was added prior to the DNS switching it over. In a case like this where it is on the website and you have not claimed that server, you need to claim it prior to it fully switching over.
