Changing name server without losing hosting

I have an issue about my hosting company so I want to solve it with using Netlify. I have bought both domain and hosting from the same local company named IHS. The company said I have to change name servers to IHS name servers to use hosting as a backend. I have changed name servers but DNS propagation takes very long, I can’t reach my website from some locations (by using VPN). Also I could not create wildcard DNS with IHS. So I decided to move name servers to Netlify to fast propagation and more flexibility. After moving to Netlify name servers, I couldn’t create configuration to use my hosting in IHS so my site is not reachable from anywhere. How can I configure my Netlify DNS to use hosting in IHS?

hi there, did you give this a read through already?
