In order to point your domain to another IP you have to change its DNS records. Usually this means changing your A record. This differs from registry to registry. But in short the registry has to host dns records.
Currently the .ls registry does not host dns records so this isnt possible for all .ls domains. But the simple solution Zeecom offers its client in relation to .ls domains is to point the domain to external dns hosting platform (e.g. cloudflare.com) and then point the A record to the specified IP address. This will achieve the same results.
