How could i change the IP address of my server

Create a support ticket and they can do it for you.

While what @acanton77 says is probably true, my first question would be "Why?" I can guarantee that "Why?" is the first question the support folks are going to ask you as well (I used to work in support once upon a time).

If the change would be to escape your Linode's bad "internet reputation"; avoid some blacklist; avoid taking responsibility for bad behavior on the part of one of your customers/users; or any other non-technical reason, for that matter; that wouldn’t be compelling enough for me.

While I can’t speak for them, I can imagine that Linode’s response would be very similar…and they probably have a zillion technical/policy reasons to justify their position.

escape your Linode's bad "internet reputation"

Some IPs that Linode assign to new accounts have a bad reputation and/or are blacklisted because of actions made by the IP's previous owner. In that case I'm sure Linode staff will make a change.

It's not up to me. It's up to them… If they want to do it for the reason you stated, that's up to them.
