I own multiple domain names on Alibaba, but they are currently directed towards an unknown external DNS server.
I want to change this and point them to my personal web server.

Alibaba offers a paid service called "Alibaba Cloud DNS", but I don't want to pay for each domain. Instead, I am searching for a free DNS server that allows the setup of A records.

Does anyone have any recommendations for such a service?

CloudFlare is worth a try.
