My domain is worldlightingservice.com

I've been able to work out a lot of issues that I had from searching on https://mxtoolbox.com/ (A records, dns, smtp, blacklist and many others) but I'm not able to work out the reverse DNS lookup. I just can't figure this out.

My .com domain is hosted in Globat and there I have everything pointing to my server on my premises. When I do the lookup on worldlightingservice.com it points to my IP where I have the mail server, which I think is ok. But when I do a lookup on the IP it gets to my hostname assigned by my ISP.

nslookup 186.136.111.143 143.111.136.186.in-addr.arpa name = 143-111-136-186.fibertel.com.ar.

How can I change this?
Do I have to work it out with my ISP?

Right. The ISP manages the reverse lookup zone for the ip address space they've been assigned.

How can i change this? do i have to work it out with my isp?

Yes. You'll need to contact them and ask if they'll create the PTR record for you that you wish to have.
