I run a small server for me and my friends. It usually runs counter strike.

Problem:
I have a dynamic IP and the router disconnects a lot.

I have a no-ip account and I was wondering, if I ran a webserver on the server and people went to my URL, is there a way some code could display the server's external IP address so they know what the IP is of the server to join?

I hope I make sense
Thanks

so your saying the ip they need to connect on is based on your ip because the server for whatever is a program that bases that info off your ip and other info... so if your ip changes so does there server address, and you want them to be able to check it to see what its current address is from now on?... i hope i understood that part right... also i dont think you can do that i may be wrong though ... no way to get that ip to stay manual & locked as is? then just post the ip info of the set ip after that...

That's exactly what I want duckman.
I know people can ping the no-ip address in cmd but some people aren't that computer proficient, and it's a pain.

alright, no way to set a perment ip for your pc then? how does that ping no-ip thing work i mean if you have a dynamic ip and its always changing hows that work im unfimiliar with this a bit myself... if you can do it threw command tho theres probally a web command as well, maby some1 else on the forums will know of it...

If your site runs PHP, you can do this:

PHP Code:

<?php echo $_SERVER['SERVER_ADDR']; ?>

That will tell you the IP address of the server.

Duckman. no-ip is a server (noip.com) that offers URL's for people who have a dynamic IP address (ie, IP changed every time a connection is made) a way to find their IP address anywhere.
Mine, for instance is jackdw.no-ip.info and if you were to type that into remote desktop connection, you will be faced with the login screen to my server. noip replaces the need to remember an IP or have to worry about the router disconnecting and issuing a different IP address when you are running a website or wanting to access your PC via remote desktop.

Namenotfound, the site doesn't exist yet but I will install a php/mysql webserver (apache). What do I do with that code?

Just put it in the page, make sure the page has a .php file extension. For example "mypage.php" instead of "mypage.html"

It will work as soon as you paste it in. Just paste it where you want it to show up, where ever you put it, on the page you'll see xxx.xxx.xxx.xxx (but with actual numbers, that's the IP address for the server)

Problem:
I just tried it on a webserver I have access to and it shows it's internal 192.168 address rather than the external IP...

Then create a batch file or VBscript for them to run to ping your Domain Name and return the IP address.

And I guess I am kind of confused on why they need the IP address to connect to your server. What is wrong with just using the domain name. Kind of the whole point of DNS.

thanks for the info jack i kinda new 1/2 that but was confused on some of it appreciate it

When I go to http://jackdw.no-ip.info it prompts my for the login information of your router.

[jackdw]

MMJ, that would be because I am yet to forward port 80 to the server as I am still setting up the game server with a friend. If you were to try it in remote desktop when the server is on, you will get a login screen because port 3389 is forwarded.

Squashman, for some reason I don't think the program that connects the games (steam valve) accepts anything other than numbers and dots in the IP address box. I may be wrong and I cannot test it myself as I am on the same network and have to connect by using 192.168.x.x

The IP is internal because you didn't set the server up to be accessed from an outside source yet. I'm assuming that's what it is.

[jackdw]

The server I tried it on has a load of ports forwarded to it.
80
21
3389
2800
2900

Surely port 80 would make it display the external IP...

Port forwarding won't do the trick. I'm with Squashman on this. Using the domain name is the key. So, maybe using PHP to do a DNS lookup on jackdw.no-ip.info will return an IP address that can then be posted on the webpage?

EDIT: Looks like using the PHP function dns_get_record() will do the trick.

Peace...
