I want a free script like no-ip.com

[Visual Basic.Net]

Hello,
I need a free script that do like www.no-ip.com. To give my site members the ability to take a subdomain in my site that is alternative for the ip. So they not need to use their IPs but the subdomain in my site. like:
www.no-ip.com
www.dyndns.com

Thank's

That isn't done with scripts, it's done with software and hardware applications on the server(s).

could you please explain that to me. I want to know the mechanism (The way to do that & what I need exactly to make a site like that)
- I thought that it is a script like the Blog script which gives Subdomains but the only addition is that the script update the ip of that subdomain to be the ip of the user that regestered that subdomain in my site. Is this true?!
thank's

you could do it with a script if you use a catch-all A record on your domain name and allow the script access to httpd.conf to add virtual server records.

Thank's alot penagate. Could you please give me an url or some thing that explain how to do that ? a lesson to program such script or a prepared free script.
Thank's

Actually, I overcomplicated it. You do not need to create virtual server records; you could simply handle the domain switching using PHP.

Exactly what you do depends on what level of service you wish to provide to your members. If you want them to have FTP access and so on it is probably worth investing in a hosting solution such as cPanel/WHM which will handle all of the administration of that for you, including managing system accounts and virtual server records and so on. If you simply want them to be able to create a few pages dynamically via a PHP content management script that you provide, then you can use a catch-all record and a script which reads the request host name and URL and serves the appropriate page from a file or database or such.

If you explain your needs in greater detail we can be more specific with what you need to do to achieve it.

What I need exactly is diff. from what you thought.
I need The Following:
I need to make a website like www.no-ip.com. this web site doesn't provide a webhosting service. But, some body make a web site on their computers so any body who wants to accesses their sites must write the ip address of their computers. Now, The ip address is changing, because of that they want a domain like name.mysite.com I want to provide that subdomain for them as a service. That subdomain is reffer to their changing IPs. So there is a form in the my site allowing them to update the ip address that their subdomain refers to.
I hope you understand me.
Thank's alot bro

hello! anybody?

Are you looking to create your own Dynamic DNS server? The bottom of that wikipedia article links to

http://gnudip2.sourceforge.net/
http://www.dyndnsservices.com/

You may have to search for free ones.

freedns.afraid.org is a nice service, I use it for myself and any domains I host .

I mean if you really want to get into the headache of DNS, you need to have 2 DNS servers each in different locations. (This is according to the RFC).

This is very easy if you have a DNS server that will grab records from some sort of database (I don't think bind will do it, but I do know of one...but I will let you search for that one .)
