IIS: How to map a domain name to a web site

This post explains how to map domain names with IIS web site

Assumptions:

• We have IIS hosted on a server with static IP and internet access (:|)
• We own a public domain name (:|) which is to be mapped (:|)
• IIS version 5.1 and above

For demo, I am assuming following values

• server IP address : 222.222.222.222
• public domain name to be mapped: map.jyotsna.com

Please note that these values are for demostration purpose only. I, in no way, own these.

To do:

1. Add and ‘A’ record to your DNS settings with value = IP of server. So my “A” record for jyotsna.com has value = 222.222.222.222
2. Create a web site in IIS – is needed. For demostration, I am going to use “Default Web Site”
3. Right click the concerned web site -> properties. In the “Web Site” tab, click on “Advanced” button.

   

4. In “Multiple identities for this Web Site” section, click “Add” button.

   

5. You now need to mention three values
   
• IP Address – this is IP address of the server. In my case it will be 222.222.222.222
• TCP port – I want this website to be available on map.jyotsna.com irrespective of the actual IIS port assigned to “Default web site”. Hence I am going to specify 80. If I wanted the site to be available on map.jyotsna.com:666, I would have specified 666 as this value.
• Host Header Name – map.jyotsna.com
6. Click on OK/ Apply to close all windows. There is NO NEED to restart IIS to reflect the changes.
