comment How many web servers will I be able to run with a dual core processor?
Thanks, you gave me valuable advices. My goal is to have some low access sites, and if they get bigger, then move to some dedicated servers, but I want to try and test how I can operate with different servers, that is, for example, having dedicated SQL servers, load balancing, etc, and since I will have only 1 machine I wanted to know how many ubuntu servers will I be able to run to test these interactions, I mean, how many resource intensive is operating system only.

comment Subdomains for server behind NAT
I'm new to DNS too but I had some past experiencing. Not sure if I understood you, but you if you have a DNS you can have as many subdomains as you want. You specify the subdomains like you do in dnsmasq for local server. Your web server must have a public IP too. That way, this is more or less the events that will happen when someone requests asd.yourdomain.com: Request to registrar DNS IP for domain yourdomain.com - Ask DNS where to look for asd.yourdomain.com (Should be an IP) - DNS gives an IP, and the browser goes there - Your apache is listening for it and serves the page.

Other thing, that I never done, would be to have your own public DNS. So you register a .com domain and you add your DNS's IP (Normally you need 2), so you would need to have at least 2 public IP's. That case you would control your subdomains in internet, because when you try to go to www.yourdomain.com, it will go to your DNS ip to resolve it. And that DNS will point the user to the right direction, that would be that IP or another IP, depending on how you configure your servers.

No you cannot do that. If you use a wildcard, all subdomains of your afraid.org subdomain will be resolved to your IP. Even inexistent one. Example, pinging to asdkj.x.afraid.org will resolv to your IP. That's a wildcard. Otherway you need subdomains. And these subdomains must exist in the public DNS to be accessed from internet (not your local dnsmasq). If you don't use a wildcard, as you said you only have 5 subdomains that you can point to an IP.

comment How to register subdomains on dnsmasq
Yes it's for LAN, but I would like to allow my DEV01 server to publicly its subdomains to the DNS automatically (I have a server running dnsmasq), I mean, to do not have to edit DNS config file? I wonder if that is possible or I will always need to force it editing the DNS config file.
