I’ve never done it but my understanding is this:
(1) you need a static IP address. Your computer (which is acting as your web server) must always be connected to the Internet at the same address. Most Internet conection plans give you a dynamic IP address – it changes regularily. You will need to ask your Internet provider for a static IP address. This will probably cost extra.
(2) you need to point your domain name servers to your IP address. This way, when people type in mycoolsite.com the name server points them to your computer’s IP address on the Internet (now you see why you need a static IP address).
(3) you need to ensure that port 80 (http) is open (not blocked by a firewall). If you need to serve secure pages, then you also need to ensure port 443 (https) is also open. If you also need ftp access, then you have to ensure that ports 20 (data) and 21 (command) are open.
A quick search reveals that some companies (like this one) claim to allow you to run a site on a dynamic IP address as though the IP address was static. NOTE: I have no experience with this company or others offering the same service, so I cannot evaluate how true their claims are). Proceed at your own risk. From what I can see, they do this by having you prefix your site to a choice of domains they have (like mycoolsite.no-ip.org, or mycoolsite.servegame.com) andc with a bit of software magic, they redirect to your server (even if the IP address changes). I presume they are able to do this because you have to run some software on your server. I presume the software keeps their server informed of your IP address, so even if your IP address changes, they get updated about it.
You can see which ports are open on your computer by using GRC’s port scanner. Click on Proceed then click on All Service Ports.

Sorry, I thought my response from March 17 would point you in the right direction.
You can definitely modify the hosts file on the remote computer so that when you type in mycoolsite.mine it redirects to the computer serving the site.
In this case, you would modify the hosts file to point to the networked computer (you will have to find out the IP address of that computer).
You will also, probably, have to modify the httpd-vhosts.conf on the server computer.
This is about as much as I can help because I don’t have any networked computers.

Hi,
Can give me a answer for my question asked on 19 march

hi,
Is it possible to give the name to my ip. for using the name can we able to access my system from another system.
eg:
my ip is 123.21.232.12 for this i wanna give a name like kishore.if i m trying to access my system application from another system we just mention the ip and port and application name there instead of ip i wanna use some name. Is it possible?
if possible tell me the answer please.
Thanks in advance

There is no problem in assigning a URL a domain name.
In the tutorial I map the website addressed by:
localhost/joomla16
to http://www.joomla.16
You have to enter the appropriate information in the httpd-vhosts.conf file. See the section Getting Apache to Serve Your Web Site (steps 6 to 10).

I have never used Tomcat so I am not familiar with it. From what I’ve read about it, Tomcat seems to be a different web server.
You change the domain name using the hosts file on your computer. For example, adding the line:
127.0.0.1 www.google.com
will cause all requests to http://www.google.com to be redirectd to your localhost server. But this is not enough. You need a localhost server in order to serve up web pages.
The web server can be Apache, Tomcat, Microsoft IIS or something else. But you need to configure the web server as well. My instructions are for a system using Apache server (as bundled with XAMPP – XAMPP is just a prepackaged collection of Apache Server, MySQL database, PHP, pear, and some other utilities).

Hi,
can we able change the domain name with out tomcat or xampp.
Thanks in advance

hi,
I have a doubt. Can i give my ip and application included while i change my domain name e.g: 11.21.34.125:8080/apex like this can i give in the host name?
Please help me in this
Thanks in advance

Oops, sorry about that.
Perhaps these pages would be of use:

actually i am trying to do url masking for this i m asking the doubt. thanks for your valuable suggestion.

I’ve never tried running Apache over a server, however, you might want to check out the following sites for additional information:
Can’t start Apache with mapped network drive – the solution seems to be to use UNC path instead of mapped drive.
Alias network drive Apache Server – the solution is the same as above, use a UNC path
Using Apache over a Local Network – the solution provided here is to edit your hosts file to map domain names to IP addresses (in this case, the IP address of the Apache Server.
Accessing XAMPP Over a Network – here they recommend checking that Apache is listening to port 80, not 127.0.0.1:80. This requires modifying the httpd configuration files.
Unable to connect Apache over LAN – some good network troubleshooting tips.
I hope these give you something to work with.
