Internet Anonymity Concerns - Hiding Your IP Address by NetConceal,
Inc.
In today's world of globalization and wide spread of computers, Internet has
become increasingly popular way for communication, for expressing yourself, for
sharing your mind with everybody. Popular types of Subscriptions include web blogs,
instant messaging, chats, forums and many others. Just a few clicks and
everybody in the world knows about your point of view on politics, culture,
science, relationships, whatever, since quickly evolving technologies bring
Internet to millions of people around the world.
But no good comes without bad. The worst thing to consider about many modern
technologies such as Internet is a complete lack of privacy. Sitting at
the front of your computer screen and surfing the net you are being watched
constantly, by many people and organizations, interested or not. How is it
possible? Let's see.
Internet is based on IP - Internet Protocol - special network protocol designed
at the beginning of 70s for U.S. defense purposes, but has become widely used
solution today (take a look at
Internet History for more information). Basically, most today's
computers are connected by IP, and its extension, TCP/IP. We will not dive into
details of TCP/IP here, but rather give a short explanation and point to major
privacy concerns. Main idea of IP protocol is a set of independent nodes
(computers) connected somehow between themselves, each node has unique
identifier assigned to it, and special rules exists which help computers
exchange data with each other through intermediate computers, called "IP
routers". The unique identifier is called IP address, and every
networked computer must have it in order communicate to others. To view your
current IP address, run "ipconfig" from command line under Windows, or
open web site like www.netconceal.com or
www.showmyip.com.
Ok, but what's wrong with my IP address? Like a regular address (e.g.
your postal address), IP address identifies your location, no matter how
you are connected to the Internet. For example, DSL connection from your home
is managed by ISP (remember, you have to sign agreement with ISP, and your
actual and billing addresses are there). Wireless connections, such as GPRS or
WiFi are being tracked as well (GPRS stations are able to determine your
position with a mile precision, WiFi are even more location-bound), and service
providers always register and identify you as a subscriber. Try web sites like
www.ip2location.com to see this in practice (the information is not exactly
precise in all cases, but remember, technology improves daily!).
Every time you surf the Internet, your IP address is publicly visible to
everyone on target network Subscriptions, therefore, your actual location and even
name and age can be tracked as well. Of course, this costs something (they need
to contact web site owner or hosting provider, and ISP or WiFi access point
owner), but interested parties can implement this fairly easy. This is very
serious point to consider. For example, you submit blog article, and express
your opinion about politics, criticize something or make really controversial
statements. That's was just an opinion, relax, everybody. But someone, being,
for example, a religious fanatic or simply paranoid, can find you and shoot you
right at your home. What's the hell, why? That's true, simply because he knows
EVERYTHING about you, your IP address, and thus your name and physical
location, since all web sites keep logs of IP addresses accessing them (once
you submit your post, web site records a number of entries in its log file,
putting together your post and your IP address).
Just for demonstration, 4 simple steps to know everything about specific person:
1. Retrieve web site logs (not a problem for site owners, they already
have them). How can these logs be retrieved by anyone? Simply by contacting web
site owner, and many of them will give theirs logs away with easyness, don't
worry. Just send e-mail using published contact information (click link like
"Contact Us"), write words like: "Some guy who is using your site is suspected
in credit card fraud, he has stolen my money already!", or "The person with
nickname 'blackjack' from your site is promoting child porn, we need your web
site logs for investigation, thank you." and 99% - you'll receive desired logs.
2. Analyze logs. For example, get timestamp of specific blog post and
search for records matching this timestamp, then compare URLs of web site
request and extract IP address from log entries.
3. Obtain IP address owner (the Internet Service Provider, ISP). Use
www.ip2location.com, it displays ISP. For well-known ISPs like Verizon - you're
almost done. Otherwise try looking it up in Google and find their web site.
Half an hour and you'll surely find it.
4. Contact ISP, supply IP address, and say something like you did in
step (1), and they'll easily reveal user of their IP address, because they
don't want problems with that user. That's it.
Is there any way to protect you against this? Relax, really good solution exist
and the rest of this article will point you right there.
Basic idea of all privacy solutions is faking of your real IP address. How is it
accomplished? Solution is based on intermediary computers, which are placed
between you (the person who wishes to hide himself from everyone) and target
web sites (and other network Subscriptions - such as instant messaging, file
sharing etc). Those computers are called 'Proxy Servers'. How does Proxy Server
work? Very simple: it's just like a very simple tunnel between you and web
site, all data sent by you to web site or received by you from web site are
passed through proxy server as is, using special SOCKS protocol (don't mess
with foot socks, it's just a coincidence :). What's the difference? Exactly,
target web site sees Proxy Server IP address, but not your real IP. And web
site logs keep Proxy Server IP but not your real one as well. Sound great, but
how to use this?
Anonymous Proxy Server lists are published throughout the web on special web
sites, for example www.proxyblind.org. Actually, proxy server list looks like a
simple sequence of IP address : port number pairs, for example:
123.43.12.96 : 1080
98.15.13.17 : 1080
150.19.87.31 : 1080
Choosing proper Proxy Server from such lists can be a tedious task, some of them
may be valid, and some are not. You just test them one by one, select valid
ones and save them for further usage. This work must be repeated each time you
want to use proxy, since Proxy Servers get closed very often. After choosing
proper Proxy Server, you have to connect your application (web browser, instant
messenger, whatever) to it and work. Try configuring your application for use
with proxy server. For example, MSN, Yahoo! and ICQ support SOCKS proxies, but
some programs do not. Microsoft Internet Explorer and Firefox web browsers also
support this, but you must select another kind of Proxy Server - HTTP proxy (in
opposite to SOCKS proxy).
Special software was developed to address the issues listed above - NetConceal
Anonymizer, it keeps you free from manual proxy server checking, SOCKS
configuration and supports ALL applications. Actually, a few clicks to
hide IP address and become anonymous.
Download NetConceal Anonymizer
now and try it. Once the installation is done, NetConceal Anonymizer is started
automatically, now click the 'Launch Web Browser' or 'Launch Other...' buttons.
Proxy selection is done within a minute, then application is started and you
can use the Internet fully anonymous, since your real IP is invisible to
everyone. Too good to be true? Please try it before criticizing.
