How to access the subdomain of an IP address in the browser?
FirefoxBrowserWebIpIp AddressFirefox Problem Overview
To get to the IP address of an example website, you just visit
subdomain.example.com
However, if I try to visit
subdomain.2.1.33.111 (example ip)
Firefox returns an error.
Why?
Firefox Solutions
Solution 1 - Firefox
All browsers will return an error for this. The reason is that subdomains are part of the DNS (Domain Name Service) system, where IP addresses are related to the underlying IP protocol.
The best way to think of this relationship is that domains (including subdomains) are human-readable labels which DNS then allows you to point to IP addresses. It would not be very catchy to have an IP address as your website on a TV ad, for example.
There is much more detail on DNS and IP addresses if you want to delve into more detail than this.
Solution 2 - Firefox
If the aim is to serve several application on server without an assigned domain. Best way is to use ports
2.1.33.111:8080
Solution 3 - Firefox
This isn't possible via firefox. However a work around is to edit your OS hosts file see: wikipedia.
Create or edit and add a line like:
192.168.1.100 subdomain.example.com
Remember to remove the line when you're done!
Solution 4 - Firefox
You can't mix a subdomain (DNS name) with an IP (no DNS name)
Try to use /etc/hosts file. For instance:
# IP Hotsname
2.1.33.111 subdomain.example.com
For Firefox It's ok but Chrome resolves names in a fancy way.
Solution 5 - Firefox
A hostname is a domain (or subdomain) name that has at least one associated IP address.
The associated IP address to a domain name might differ for subdomains.
You can get the associated IP address of a domain (or subdomain) with nslookup.
Try nslookup example.com vs. nslookup subdomain.example.com to see the difference.
If firefox (or other browsers) you can either enter the hostname (e.g. example.com or subdomain.example.com) or the IP address (e.g. 11.22.33.44).
