Hi everybody!

I would like to now, If I'm using Apache and I want to see my website from anywhere do I need a PUBLIC IP?

If I'm setting up an FTP server to access from anywhere Do I need a PUBLIC IP?

What If I'm using PC ANYWH*RE an d I want to Loggin like a remote client, Do I need a Public IP?

Thanks for your colaboration.

of course, internal IP's are exactly what their name suggests in turn wouldn't get you very far out in the internet world
your internal ip would work internally and your external ip (what you call public i am assuming) would work outside your home.

Yes, you do.

It doesn't matter if it's the ip address of your router, which could then forward through to your apache / ftp server, or if you have a direct dial connection from your apache / ftp server.

The main point here is: You can't get on the web without a public ip address. This is what your ISP gives you when you connect.

You may have an ISP then assignes you a permenant address, in which case it's easy to remember, or you may be given a different one each time you dial up, in which case you would have to make a note of it each time you connect.

Thanks DrOzz, Thanks Mike,

Thats is exactly what I'm asking about, I'm not an English native speaker I'm From El Salvador and we call Public IP (external Ip I think), to an Ip that allow to you to have access to you web server (for example) from anywhere,

But It's there any other way to avoid this, or is requirement?

I tried to setup a web server before, but just me and other terminal from the same ISP network that provides Internet to me could see it.

What about an FTP server?

If you're connected to the internet then you have a public IP address already. However with a lot of internet connections sold to consumers (ie. not to businesses) this IP address can change every time you connect, or even every so often, dependening on how your ISP sets it up. If you really want to do web hosting then contact your ISP about signing up for a business connection with a static IP.

There is a way to get around the changing IP problem - register your domain name with a dynamic DNS place like http://www.dyndns.com/ and then run ddclient (http://ddclient.sourceforge.net/) to update your IP address whenever it changes. That way you can have a domain name that will always point to the right IP address.

Thanks so much tkedwards.

To find out what the public IP assigned to you by your ISP is, you can go to this little mivascript I wrote:

It'll tell you what YOUR public IP is at the time you access it.
