Wildcard DNS Configutation

Hello everyone,

I have been making my way through creating my site and I must say the support in this community is wonderful.

I have been given a warning notification while setting up my multisite that says my Wildcard DNS is not configured correctly and that I need a wildcard configuration in my DNS. I reached out to the hosting company I am using for now. They said it would cost $199.99 to have this done. Is this normal or is there another way to do this?
