Subdomains?
 

Hello,

I hope everyone is doing well.

I have a question with respect to subdomains.

I have a www.domain.com registered and hosted out there on the Internet with an ISP. Everything works well.

I also have in our organization a couple of static IPs coming into the building. I have set up a webserver to host an internal collaborative calendar web application and it is accessible from the general internet if you know the static IP no problem.

Question: How would I go about so that if you typed in "webserver.domain.com" you could be taken to the static IP hosted onsite, but if you type in www.domain.com you would be taken to the external ISP hosted site? Is that even possible?

Thank you.

It's possible, just set up your DNS, for the domain, to direct webserver.domain.com to your static IP and make sure your web server won't reject the incoming requests. I'm guessing your isp handles the dns for you so you'll have configure it through them.

You need to add an "A" record to the zone file for the subdomain.
