Hi guys

I need to get the external ip address of company machines that is through
out the nation.
this became problem for me because most machines are behind professional
firewall.

when I do ; reqest.servervariable("rmt_addr) I get the public ip address if
they don't have professional firewall.

thanks again

Uh.....that's the whole point of a firewall...to keep people out.

It's annoying, isn't it. Dreadful. I have a similar problem with my bank on
the High Street. Every time I go there at night when they are closed I can't
get in because they've locked the door. How annoying.

I don't think you've explained the problem completely because what
you've said doesn't make sense.  Regardless of whether or not a machine
is behind a firewall or not, if it's connected to the Internet then the
connection has an external IP address.  If the machine is behind a
firewall the firewall has an IP address if it's connected to the
Internet.  In either case the external IP address is visible.

'net side unless they have in-house nodes and even then you still get the
outer IP, but not the inside 192... type of course.  Just open a command
prompt and ping name.com and it'll return the IP of name.com.  Tracert will
do the same thing but ping is easier & faster.

Or do I misunderstand something?  It works for all my secure site contacts,
including banks.  The IP is public and never hidden; if you can't do the
above, just go and use a whois.

No big mystery.

Well, I must admit that I don't understand this Internet stuff, Pop (never
been involved with it) but surely a firewalled broadband router will simply
return the temporary address it has been allocated by the ISP to which it is
connected, which does not actually identify the computer that is currently
using that address? Isn't that the way it works?

Show quoteHide quoteTrue; that's how it works.  Although an IP may not change for days or
sometimes even weeks at a time, unless the User is paying for a "static" IP
address, they do change.  Nearly all IP addresses are dynamic.  Nothing
beyond that connection point is identified UNLESS the User chooses to do so.
   For instance, one of my posts yesterday shows in the Headers that it came
from 141.149.211.213, which is Verizon.  I may or may not have that same IP
today.  If that were an e-mail, it would even have my machine name in it,
because my mail client "chooses" to put it there.
   Some places, like a bank or like business, will have static IPs.  In
those cases, or even in my case if you got the IP to give you the routing,
you could then pin it right down to my specific computer.  BUT, no bank is
going to allow anything inside their IP port to be exposed to the 'net.

If you have a more than passing interest in this stuff, let me know and I'll
throw out a couple of URLs for reading purposes; it's the kind of thing
that, if you discuss only the basics, you're misleading things in several
possibly different ways depending on what the reader audience is looking for
and the context of their thoughts<g>.

   For your purposes I'd recommend simply pinging the URLs you're interested
in.  Or look them up with a whois if you've a lot to do.  To find those
sources, just do a Google search for "whois" (no quotes needed) and you'll
get a boatload of sites that'll look up an IP based on a site name for you.

   Or, if you want to see what all is actually available en toto, go to a
place like www.dnsstuff.com  .  There you can find just about anything about
any IP that's public information, anywhere in the world.  Without joining
though you're limited to how many lookups you can do, so read first, then
lookup.  I've joined because I use them a lot in my spam fighting tactics.
   How do they know you've been there before and when to lock you out?  They
keep track of your IP number and pieces of your Access envelope.  Soon's
your IP changes, you'll be able to do more lookups again.  Unless they've
changed something in about the last 6 months, anyway, that's how it did
work.  I don't keep close track.

Show quoteHide quoteI have an always on DSL connection but I don't pay extra for a static IP
address.  However my dynamic IP address stays the same sometimes for
months.  But the point is that whether it's temporary or permanent the
IP address is still visible to the Internet or your machine won't be
talking with any other machines on the Internet.

It doesn't identify the computer behind the firewall but the connection
still has a name and an IP address.  If you look at the header of this
message you can see the temporary name (which happens to include the IP
address) and the IP address on the NNTP hosting line.

I was trying to get the OP to explain better because what he said made
no sense.  I ~think~ he meant that certain machines use a proxy.  If
that's the case then I'm not sure you can obtain the IP address of a
machine behind the proxy without some sort of proprietary
communications.  The only visible IP address in that case would be that
of the proxy.

That's a good point about proxies.  That could indeed be what the OP was
getting at without realizing it.

My cable connection stays at the same IP for months as well.

The way DHCP works is when the lease expires, and a new one is requested,
the request is passed along with a preference to the current/last IP
address. So, if the modem's on 24/7, the whole process takes a few 10's of
milli-seconds, which is why even tho it's dynamic, it stays the same for
months on end.

Here's what else I've done.....I set up a cjb.net account to act as a DNS
lookup only, not a website re-directer. On my server, I've got an Auto-IP
updater running. The updater checks my internet IP once an hour, and if it
changes, it automatically logs into CJB.net and updates their DNS.

I've had this setup going for years....very reliable....I can get to my
PC/network from anywhere just using *********.cjb.net as the IP/server to
connect to.

Good thing I wrote this post. I'm planning on converting my server over to
some Linux distro in the next week or 2, and completely forgot about the
IPUpdater service.......hmmmmmm......I'm hoping there's a Linux version of
the one I use.

Show quoteHide quoteThat's an idea I hadn't thought of.  I get my current IP address at the
start of every operation (every five minutes) and use it in SQL for
database replication that works fine with IP address alone.

Since I'm not hosting my web site I don't think it's necessary to go the
extra step and update the DNS every time the IP address changes but it
is a cool extra step.  :-)

Why not using the free DynDNS-service?
There are also Linux-UpdaterTools on their site:

@TK2MSFTNGP06.phx.gbl:

Show quoteHide quoteBecause I'm using the free cjb.net service. I prefer my 'url' to be
*********.cjb.net, rather than *******.dyndns.org. At least with the
CJB.net address, if people don't know about it, it's not apparent that it's
a dynamic address from the name.

Thank's for the tip on the Linux updaters. I'll need that sooner than
later.

The world is not round.
You can't get there from here.
You have to start from someplace else.
If the machine is behind a
networked IP address, aka router,
you'll never reach it.
Unless the machine has sent a remote support request.
And that's even "iffy."


Show quoteHide quote

Never? Why is so?? Ofcouse you can, but only if you configure your
router for port forwarding to that exact local machine. No it's not
"iffy" (whatever it means :) ).

That still doesn't mean that from the outside world, you'd get the inside
PC's IP. Going thru a NAT box, it will still show as the global IP of the
rtr WAN port, not the mapped PC's IP.
