PureBasic Forums - English

PB wrote:> try http://myip.dk

Okay, here's the results from today's ADSL session:

http://myip.dk = 203.26.24.211
www.showmyip.com = 220.245.73.143
www.ipaddressworld.com = 203.26.24.222
This forum's "IP" button = 220.245.73.143
My code from this thread = 220.245.73.143
Client IP address = 220.245.73.143*
Server IP address = 202.7.162.108*

* = Obtained by double-clicking the modem icon in the System Tray.

So... I really don't know what the heck is going on. However, the
majority of them seem to be 220.245.73.143 so I guess I should use
that as the "real" IP address when wanting to remotely access my PC,
and it's good to see that my PureBasic code gets the majority one.

I'm still working on it.. but if you want to be SURE.. for right now..

Just launch the PB webserver, and try to connect to it using those different
ip's.. via your browser ..

i get same ip from all those sites.
But dosent ZoneAlarm have a way of faking your ip? i dont remember the basic zonealarm having it but what about if you have PRO?

I get the same at all adresses, too.
Perhaps you - or your provider - is using some proxies ?

> But dosent ZoneAlarm have a way of faking your ip?

Don't think so... I don't have the Pro version, just the Free one. But even if
ZoneAlarm is not running I get all those different results, too. It's okay, I'll
just use what PureBasic returns, since that seems to match the majority of
the sites I listed above.

> Perhaps you - or your provider - is using some proxies ?

Not me... I don't understand networking enough to install anything like that.
I guess it could be my ISP, since I have a dynamic IP address with this ADSL
account, instead of static -- but I specifically chose that for privacy concerns.

Gentlemen,
about the IP addresses. I happen to know a little about IP addresses and I'll share with you my 5 cents worth.

Internet Service Providers receive a bunch of IP addresses from a central controlling body. They often pay a helluva lot of money for them because IP addresses following the IPv4 (IP Address version 4) is not enough to cover all machines.

When IPv4 was concotted, it was thought that there would be enough IP addresses to go around. This means (in theory) every machine connected to the Internet would have its own individual IP address. However, in a very short time, due to the rapid expansion of the World Wide Web, those in charge of allocating sets of IP addresses to ISP's could predict that the given IP Addresses under IPv4 would run out in a short time.

So, they made the allocation of IP Addresses to ISP's smaller and charged them more and the ISP's treat their bunch of IP Addresses like gold.

Now here comes your confusion.

ISP's operate from behind a wall (usually a NAT Network Address Translation Server). When 100 users connect to the ISP, instead of allocating 100 individual extremely valueble IP Addresses, they allocate just one.

How does this help? All those connecting to the ISP get an addition to their IP Addresses; Therefore you connect as 203.26.24.211. As soon as your request is received by your ISP you get a /24 (for example) attached to your IP Address thereby making your IP Address now 203.26.24.211/24. Your ISP attaches one of its IP addresses plus an attachment and Your request is then sent onto the next server down the line to resolve your target url. This server operates under the same rules and attaches its own IP attachment. Now when the target url is located and sent back, a reverse translation is made.

You follow me?

You, personally do not have an IP, no matter what your local telekoms company told you. They allocated some number to you (dynamically) that isn't really a valid IP Address, jut some code that tells only them who you are becaus you are really connecting from within your local telekoms network. Then they translate this IP Address into something else via a NAT and send it on its way to another NAT that operates on the same principle.

Make sense?

That's correct. Work just like someone who has 10 computers in their
house. They are all using the same IP. The router is translating them
to external sources.

But that doesn't change things here.. I guess it would change things for
certain ISPs.. who try to prevent people from serving, ftp, http, smtp, etc..
All they have to do is block that port for incoming connections.

Most of us are lucky, I don't have any ports blocked. I can run all of the
goodies.

But back to the reason this thread is here.. I stand by my last post.

Previously I wrote:As for the "experts" that I am refering to in my above post. Are experts
of Transmission Control Protocol - Internet Protocol (TCP/IP).

And what I've found makes perfect sense, for those of us that are behind
a firewall OR router OR both. We are trying to 'hack' our own systems by
touching outside the wall to find our number. There is no easy way. That
is why these sites exist.

I haven't found just one overall solution. I've found a few individual ones
but not ones I would integrate into any of my applications.

I will keep looking. Worst case scenario, which is actually a great idea for
me. Is the following. Becuase some of my software plans to have an
updater like, PB, and TailBite, etc.. I will end up using my own site to
grab the users IP from..

It appears that your service provider IS using a proxy.

most likely there is a (sort of) proxy or nat involved...

you might want to go to www.grc.com, there's a little tool to figure out your ip, what does it say?

Have anyone heard of dot-less IP?
And no, I don't mean removing the dots in the address
