Making Changes at the Domain Registrar
=======================================

Login to your domain registrar. In my case it is namecheap.

On the left menu, click Domain List.

Check domain name turritopsis-dohrnii-teo-en-ming.com and click Manage.

Click Advanced DNS.

Scroll down to PERSONAL DNS SERVER.

Click ADD NAMESERVER.

Nameserver: NS1

IP Address: 185.182.9.61

Click DONE.

Click ADD NAMESERVER.

Nameserver: NS2

IP Address: 185.182.9.61

Click DONE.

After adding your two name servers, click the search button to check
if they are added successfully. If so, the glue records will appear at
the bottom of this page.

Now, click the Domain tab.

Under NAMESERVERS, select Custom DNS.

Nameserver 1: ns1.turritopsis-dohrnii-teo-en-ming.com

Nameserver 2: ns2.turritopsis-dohrnii-teo-en-ming.com

Click the green check mark.

Sign out from namecheap.

Final Thoughts
==============

Hmmmmmmmmmm, I cannot create virtual server using my domain name
turritopsis-dohrnii-teo-en-ming.com after configuring DNS using Webmin
manually. It looks like I need to configure custom DNS servers at my
domain registrar first, then create virtual server,  and then
fine-tune DNS records. I shouldn't configure DNS with Webmin manually.
This is my very first time setting up Virtualmin and Webmin, so I am
not that familiar with the setup process.
