Title: IP Addresses
Post by: Riven on July 28, 2002, 01:09:09 pm
I was wonderin how they work. Every time i connect i have a new IP address but the first set of numbers is always the same. I that like an area code or sumthing? What about the other digits, why do they change. Are they line numbers or something.

An IP address is like a phone number; it's what other computers use to contact your computer. The first few digits of the IP address are assigned to your ISP, while the other digits vary as they are assigned as available. So they are an area code, in a way, but more of an area code for the internet-as in a single city, the beginning IP addresses of two ISPs can be extremely different.

You're right about the first set being an area code - if I was to IP ban that set of numbers alone then not only you but everyone in your area would be unable to access this forum. If you had a static IP and I was to ban that then only that number would be unable to connect.

There are some programs out there that can mask IPs so you can't tell what they are, others randomise the numbers (even on static IPs)...

I don't understand to much about it myself - just the basics above :)

I wish there were some good anonymous progs, the ones i,ve used always limit the amount of sites.

An ip address is TCP/IP's answer to a phone number split into four intergers. These are registered by your isp and administered by various non profit organizationd depending on where you live.


The first set of numbers is unique to your area (as stated by Thunder) and it's size determines the size of the network you're on (The smaller the first number, the smaller the number of nodes on your network). The larger your network is, the greater proportion of the ip address will be dedicated to your host id, which identifies you on that particular network. nIt's all pretty cleaver really :D


There are various ip analyzers out there that tell you details about a given ip address (www.nic.com has one). The info you can get on someone once you have their ip address is impressive.


Most cheap isps give you a dynamic ip address (one that changes each time you connect). This can be a pain if you want to run any servers (in fact it makes it pointless: Think about what it would be like if your phone number cahnged all the time) so you can get a better, more expensive isp to give you a static ip address (one that stays the same all the time).

ok so if the first numbers are unique to the area then is there i directory of area codes? nic.com just gives me info on the isp, i wish to find a physical location by isp, nothing very specific just the area of the country.

As nefarious as that sounds, I don't care.

Get NeoTrace and smack in the IP.

Nic gives you the country and sometimes the area. Although there is no way of obtaining the address of an individual from this, just where the isp is based.


Go to the websites of the various organizations responsible for the codes.


ARIN For America (http://www.arin.net)


RIPE NCC for europe (http://www.ripe.net)


APNIC for Asia (http://www.apnic.org)

Yugh... the reason why my internet cable connection won't work for now is that AOL tells me the TCP/IP connection is malfunctioning or can't be found (something like that, don't remember ), which is not true coz under windows XP, it works just fine ( save for the fact that I can't do crap since AOL5 won't run farther than the greeting page under XP ). Already had the pb and managed to go around it, but this time I just can't remember how I did before :(

It means that when you surf, you surf anonymously. sites can track your ip address in about three lines of code (I'll use perl for this example).


open (OUTFILE, ">>/home/greg/iplog.txt");
print OUTFILE "$ENV{'REMOTE_ADDR'}";
close (OUTFILE);


If I was to stick that into the source code of an URL it would log your ip without you even noticing.


Example: (this will track your ip so don't click if that's not what you want).
