How are you going to change your IP address? It can only possible by using a VPN service but why would you do that? Well, if your network/ISP provides dynamic IP addresses then they automatically change once you restart router or Wife, new IP addresses can be confirmed by visiting websites like https://whatismyip.live
In my personal opinion, if your IP address change and ISP stays the same then there will be no problem from fiverr. However, if you change country using VPN then you may face issues from fiverr.
