Also what websites are you trying to do a tracert to?

IP addresses starting with "10." are internal addresses.

From Wikipedia

Machines not connected to the outside world (e.g. factory machines that communicate with each other via TCP/IP) need not have globally-unique IP addresses. Three ranges of IPv4 addresses for private networks, one per class, were standardized by RFC 1918; these addresses will not be routed, and thus need not be coordinated with any IP address registrars.

IANA Reserved Private Network Ranges   Start of range   End of range
                  The 24-bit Block                        10.0.0.0         10.255.255.255
                  The 20-bit Block                       172.16.0.0       172.31.255.255
                  The 16-bit Block                      192.168.0.0      192.168.255.255

Each block is not necessarily one single network, although it is possible. Typically the network administrator will divide a block into subnets; for example, many home routers automatically use a default address range of 192.168.0.0 - 192.168.0.255 (192.168.0.0/24).

If I do a tracert from this computer, in my bedroom, I get something like this:

192.168.0.1       -> this is the computer that is connected to the cable
                            modem and distributes the connection to the other
                            computers in my home.

10.2.191.254      -> this is an internal IP address, it is one address that
                              only my ISP, Netcabo, knows the machineto which it
                              belongs.

212.113.172.30  -> then it passes to a public address, at this moment the
                             packets are really in the Internet, up to this point they
                             were only on my home's network and on the internal
                             Netcabo network.

I hope it helps.

Not to sure where the other ones sre that just what was displayed after i did one
i used a program called trellian trace. and yes i am in New zealand, is it normal to have my dsl address appear twice,
i'm more than just curious, i have suspicions somethings afoot

I see my explanation fell in deaf ears... but I will make a last attempt.

You address does not appear twice, what appears twice is an internal address.

As I do not know how things really work with your ISP, I will try to explain it with my case.

My tracert command, "seeing" that it had a destination that fell outside the internal network, was sent to the computer that acts as a bridge between my network and the network of my ISP (we do not connect directly to the Internet, we connect to ISPs, the ISPs are the ones that are connected to the Internet).

That computer's address is an internal address, and although it is 192.168.0.1 (because that was what I chose when I installed the network) it could also be 10.1.1.1.

Once inside the ISP network, it travels through internal addresses for as long as it is needed, based on the way the ISP had its network installed. As this is a different network from my own network, it has a different address (in my previous example, it was 10.2.191.254, but it could have been 10.1.1.1, just as long as it is an internal address).

So, that is nothing suspicious, it's just the way TCP/IP works.

PS: although I work with computers everyday for more than 15 years, I never studied it at school, so I may lack some of the names and some of the more precise details, but I think that my explanations are enough to understand how things work, for those who are really interested in understanding it.

thanks for that, i think i understand no, it just through me seeing my internal dsl madem address appear twice.

Just for reference you can do tracert through command prompt, just open the start menu and click run -> type cmd then click OK. Then in the black window just type tracert webaddress or ip address. I don't know enough about networking to explain why 10.1.1.1 appears twice... does it appear twice when tracing the route of other websites?

If what is happening is what I said above then the address should appear twice for all tracert commands, regardless of the target, because that is the initial route the data packets must use before reaching the Internet.

Hi All
ok understanding a bit more now i think.
what i have done is do a trace via my own connection wich is via a adsl router and another trace from a available wireless network that is in my street, below are the two trace readouts, the first is my own connection to www.abovetopsecret.com the secon via the wireless connection, again my 10.1.1.1 addresss for my adsl router shows twice whereas the address for my neibourhgs wireless router shows only once.

yes any website from my own connection shows 10.1.1.1 twice
