Ok… so MSN works as a message delivery boy more or less? 🙂
Suzy83.. if you’re still reading this thread I’ll put it in the simplest words:
“It takes a bit of work, and a little knowledge of networking”There is really no need to do this unless of course one had something “promiscuous” on their agenda. Wether that be to show off, scare someone, or worse. Who knows? My suggestion is: put that person on your ignore list. :p If he’s not willing to let you know how he did it personally, or even why, then he’s not worth talking to.
EDIT:
BTW… I had to add this 🙂 hahaI never knew MSN would volentarily be anyone’s b*tch.
Interesting to know though. Are all messenger services run in this way?wivern: Yes… what I was trying to do was clarify that without making it sound too difficult (tricky when dealing with TCP/IP) 🙂 Looking back at what I wrote, I think I wrote too much. Anyway, I just didn’t want people getting the idea that they could effectively “hide” themselves with a masked or cloned MAC. Without fully understanding what’s going on you could really screw things up. I wish NIC vendors would stop calling their MAC addresses configurable though. It’s a little misleading. And I don’t know how this thread branched off on to TCP/IP. Suzy83 is probably going to get a headache reading all of this. 🙂 If they’re still reading the thread.
broku: If MSN treats peer-to-peer connections like a regular network does then YES you can get an IP by sending them a file. I’m not sure how MSN works but for the sake of argument if MSN works like a router or switch for messenger users then your IP packets must contain a destination MAC and IP. Therefor, when your computer handshakes with their computer to establish a session you will have their IP. But like I said… I don’t know how MSN works so you could be right.
Nederfox: (This is for you to study…)
Physical Numeric Address (MAC Address):
This consists of a 6-byte numeric address, burned into firmware (on a chip) by network interface manufacturers. The first three bytes (known as the organizational unique identifier,[/b] or OUI identify the manufacturer of whatever interface is in use; the final three bytes provide another unique[/b] numeric identifier that causes any interface on a network to have a unique[/b] physical numeric address. The physical numeric address functions at a sublayer of the Data Link layer in the OSI network reference model, called the Media Access Control (MAC) layer. For that reason, it’s also known as a MAC layer address (or MAC address). Although there’s more to it than this explanation suggests, it is the job of the Logical Link Control (LLC) sublayer in the Data Link layer software (usually at the driver level) to enable the network interface to establish a point-to-point connection with another network interface on the same physical cable segment. ARP (Address Resolution Protocol) is used to permit computers to translate numeric IP addresses to MAC layer addresses, and RARP (Reverse ARP) is used to translate MAC layer addresses to numeric IP addresses.“Guide to TCP/IP”, Laura A.

Nederfox:
“Wrong. Many NICs and routers have a highly user-configurable MAC address. So this does not have to be unique”
I’m afraid you’re wrong. Have you studied Networking? Do you know who the ISO is? ALL MAC addresses ARE unique and I would gladly accept proof otherwise! It’s a networking standard and MUST be true in order for networking to even be possible. Granted there may be an incredibly small chance that 2 people will have the same MAC address but the odds of getting struck by lightening 3 times in a row are greater than finding 2 people with the same MAC address. It’s a Law, Standard, and Must Have function for networking. Any test you take will tell you this. MCSA, MCSE, MCP, Network+, Security+, etc. MAC addresses can be altered through routers and programs but when packets are sent, the burned MAC address is always the same to each NIC, regardless of alteration. Change your MAC address with whatever program you use and then do an ipconfig /all and tell me it’s not the same. 🙂 A MAC address is just like a social security number or VIN for your car. You need to do your research a little better on this issue. The address you are thinking of is a MAC clone address… not the MAC address. There is a BIG difference.
As far as chained proxies… yes it will make tracing more difficult but that’s why we have computers. So we can let them sit and do all the work for us. 🙂 Even through chained proxies, one can be traced in a matter of minutes if not less. I’m just basicly saying that it’s not worth it. 🙂
smontgom. You beat me to it. 🙂 haha IP addresses do NOT start from 0.0.0.0 to 255.255.255.255. In fact, IP addresses do not even start with 0 or 255 OR end with 0 or 255. 255 in hex would equal FF, and in IP terms that would register as a 1 or “broadcast”. 0 would of course be zero or in IP terms “the network”. This all because of the mask 255.255.255.0. (telephone companies also do NOT assign numbers from 200-0000 to 999-9999, I used to work for a telephone company but I won’t even get started on that). Ethernet addresses are assigned by the Internet Standards Organization (ISO) more or less. I forget which branch actually handles the first 24bit MAC (actually the first 2 bits). Local IP addresses are assigned according to your MAC address. Your MAC address is a UNIQUE, 48bit set of numbers (hex) attached to your Network Card or Integrated Interface. The first 24bits are assigned by the manufacturer of that Network Card. The first 2bits of the first 24bits are assigned by the ISO to specific manufactures. Are you following? 🙂 ISPs are given a set of IP ranges in whatever class they are in. A, B, or C (D and E you don’t need to worry about). Each of these classes have a range which you can determine by your mask. 255.255.255.0 is class C. Now when you take both of these sets of ranges you can see how unique an IP can get. If you’re running on a router or switch or server of some sort then it possible and actually quite common for 2 people to have the same IP addresses, HOWEVER, you do not connect to THAT IP. You would be connecting to a WAN IP address. The IP address given to you by your ISP. Most IP addresses (localy) are 192.168.2.x or 192.168.1.x but you obviously cannot connect to these addresses since they are local IP addresses. But there ARE ways of obtaining the IP from someone reguardless of direct connections or file transfers. Hackers will use port sniffers or service scanners to check for open ports or unprotected services. IP addresses (WAN) can easily be obtained this way. If you’re trying to obtain an IP from someone you’re simply chatting to you could run Peeking programs such as EtherPeek (if you’re willing to spend the big bucks). But this would also require you to know how to break apart individual packets and read HEX fluently. All in all, if this kind of stuff interests you so much… take Networking classes and obtain a degree. 🙂 And DO NOT try to obtain an IP for revenge. IP addresses are traceable… even on wireless connections. Anything you do can be scanned, monitored, and traced to the very spot you are sitting.
