what kind of IP addresses begin with 39 ?


Google could'n help, I hope that someone here will:
My outbound connections appear as originated from 39.x.x.x
Using Cheops I get some connetted machines with addresses beginning with 10. say 10.x.x.1, 10.x.x.2, 10.y.y.1 10.y.y.2, 10.z.z.z, 10.k.k.k etc
All the 39.x.x.x machines have the fisrt three octets in common (39.x.x.0, 39.x.x.1, 39.x.x.2, ---> 39.x.x.127 (my machine, looks like) 39.x.x.1 would be the default gateway, as I could see breiefly looking at the cable guy's papers.
In Cheops (the version available in Synaptic) the 39.x.x.x machines are shown as computers (computer icon) and the 10.x.x.x machines are shown as "black holes" (what does that mean?)
I actually copied those settings a piece of paper:
Quote:
IP CPE Parameters
CPE Manager: hostname 1-long-name-1ncl00dingnumber-and-dashes-004-0102-09
IP 39.x.x.126
Subnet 39.x.x.0
Subnet Mask 255.255.255.0
port switch 9
Scope subnet 129.x.x.0 [but I could be wrong here; it may be 39 and not 129 after all]
MAC address 000-some-mac-address
STS requested
UM residential can be activated thtroug ISPs website.
Now, when I'm on the Internet, the IP shown by IP checkers is completely different from those above, and the IPs of my "local" network (the 39.x.x.x and the 10.x.x.x machines mapped by Cheops) wont accept neither http nor telnet connections, but I must say that I'm no telnet-guy, I could never actually log in to a remote machine using telnet (I've tried maybe 10 or 15 times in my life) not even once estabilished a connection without logging in.
I said it from the start, I'm a total newbie about linux and just little over the average computer user on windows... and that' because the average is *very* low, not because I'm good at compuers (I'm not, actually) My knwledge about network system is somewhat higher than zero, but not much.
I figured out [and I may have figured out wrong] that some of the machines connected on what Cheops maps as "local network" must be routers: I think I've heard somewhere that what routers do is actually to show one IP address to the outside and keep local addresses hidden.

OK, then, after all the descriptions and some of my probably faulty conclusions, here come the questions:

In the first place, I would like to know for sure if I am really connected through an ISP owned router or through something else and in this case, what it is.

It would also be nice to know what is a CPE manager is, an what does it do; I did found something on the web about this one, but I still couldn't puzzle it together.

And I still don't know which one of the mapped IP addresses is the router (if any) which one is the server (if "visible" from here) and so on.
What do the "black hole" icons in Cheops mean?
And the "mother of all questions" is (you guessed it):
How do I log in and tweak the configuration the remote machine (whatever it is) to fix NAT problems in Azureus, i2p etc.






Totally [OT]: I still can't believe that something like 90% of all computer users don't even know that you dont't really have to get windows and that there is a *better* alternative to it. Free! As in free speech *and* as in free beer! (By the way, I loved the slogan "Linux is like sex: it's better when it's free", The person that invented it is a genius, and I hope it was not Linus himself because that would make him *two* geniuses! (at least).

39.0.0.0 to 39.255.255.255 is an address range that is reserved by the IANA and should not be used by anybody on the internet

10.0.0.0 to 10.255.255.255 is an address range that is reserved by the IANA for private networks and does not exist on the internet at all.

You can look them up with whois on www.dnsstuff.com. Its likely that the network you are connected to is not the internet but a private network using the 39.x.x.x range which is then routed out to the real internet at some point via NAT

Thaks baldy (by the way, I'm 40 and have lots of hair he he he)
[OT]your signature quote is really cool, who wrote it? (shoud I know it? and if not, maybe you could add the name of the "queotee")

And about the LAN network: yes, that's exacly what it is.
A LAN connected to the Internet via NAT; that's why I get NAT error on Azureus (but I'm still able to download) and that's why I cant set up a node on the i2p network or a Tor server.

What I want to try is log in on one of those machines, or more than one if that can help, and try to tweak the configuratione to get rid of my NAT problems, after all, I pay for a *full* Internet connection, not a limited access one.

So once again, if someone knows something I could tray, links I can visit, tips&tricks and HowTo pages and so on... just post it!

I didn't need to check out the database, cos I knew that stuff anyway. You cannot identify what a machine is by its ip address as any allocation scheme would be peculiar to the organisation. You might work it out by port scanning, or telnetting to the device to see what it responds with but to be frank, I would suggest that unless you are part of the organisation concerned, which you don't appear to be or you wouldn't be asking the question, you leave those devices alone or you may find the police knocking on your door.

And 10. addresses are private addresses, not necessarily LAN addresses, there are such things as private WANs as well. But you probably already know that as well.

Well, to begin with, you can't be frank because you are Pete. (That was my best joke this week)
And it looks like I had one post removed by the staff, so I wont say the same things only to get another post removed and maybe even get banned, but it was not that bad after all...
Well, OK, it was not 100% politically correct either; I guess the staff want to be sure that they don't get in trouble; after all they want to keep these forums going which is the same thing that we want, so we should continue this discussion in private, if you want to.
And if you don't, that's cool, no problem.
