I went to the following 5 Web Sites and each listed a different ID Address.  The Sites were visited in order as listed on the same date and within 5 minutes of each other without any other changes.  There is probably a very simple answer, but I thought that they or at least more than one would show the same address???

The IP address is either dynamically assigned to the computer upon connection to the network, or a static value that is manually entered in TCP/IP properties.  I'm unclear if it is wise to post the actual IP addresses here.

How to Use Winipcfg to View TCP/IP Settings

At any rate, I'd highly recommend keeping your Operating System and Browser updated with fixes, patches, security updates, etc. using WindowsUpdate.

Well, they're all proxy servers. I'm not sure how AOL works (I'm from Finland so I've never used it), but it might use a proxy server which automatically uses other proxy servers (for load balancing maybe?).

ping -a 64.12.102.171
Pinging spider-mtc-tg051.proxy.aol.com [64.12.102.171] with 32 bytes of data

ping -a 64.12.96.105
Pinging cache-mtc-af04.proxy.aol.com [64.12.96.105] with 32 bytes of data

ping -a 64.12.96.141
Pinging cache-mtc-ag08.proxy.aol.com [64.12.96.141] with 32 bytes of data

ping -a 64.12.96.111
Pinging cache-mtc-af10.proxy.aol.com [64.12.96.111] with 32 bytes of data

I understand that IP address are either static or dynamic.
Marko, are you suggesting that I ping each one individually?  The only other thing that I can tell you that during that same time period when I was going to the individual sites, if in fact I would return to any of them, each one would have given me the identical response that it did the first time no matter in what order that I re-visited them.  I thought that mayby the difference  had more to do with that particular web sites own URL than my IP Address, but that was just a guess on my part.

As astaec has pointed out, first run Winipcfg on your system and see what IP it reports.  The fastest way that I know how to run it is: Click on Start>Run then type winipcfg and click OK.  When the Winipcfg window appears click on "More Info" to see the entire screen.  I make the assumption that you only have a single "Dial-up Adapter" on your system.  If so you will see the IP and Subnet Mask numbers along with various other aspects of your connection.  If you happen to have more than one adapter(you are on a LAN) you will have to choose the external connection to receive the proper information.  From here you can now begin to ping those IP's again and run Winipcfg to see if your IP is changing.(I doubt it)  I don't recommend clicking on any of the "Release", "Renew" buttons as the results of that action will vary depending on your ISP and type of connection.  But if your feeling adventureous then give it a shot.  I believe that in most cases what does happen is that the DNS, DHCP or WINS server will reassign you a new IP or update the lease.

It is that your ISP uses DHCP Dynamic or changing host control protocol. Quite often websites are off on your IP due to such devices as proxy servers being run by your ISP and the like.  It is common and noting to worry about.

With AOL you really have no IP at all as they have several servers being run at once to give the impression of speed.  It makes things appear faster on your end but is nothing that you can say that you have a designated IP address as AOL was one of the first to make such use of DHCP as they had to do it by necessity.  I am not sure where they stand these days but a few years ago despite what people say about them, they had the most subscribers over all other ISPs.

LRI41:
No, I just pinged them with the -a option to resolve the names of the servers. You can usually tell a little after knowing the name of the computer. Previously I suggested load balansing, but it could have something to do with geographical locations too if the sites would return the same IP each time.

pbessman:
> With AOL you really have no IP at all
Are you sure? Not even an internal IP? Do they not use TCP/IP for transport?



To find out your own computer's IP you can run a command called ipconfig (you are on Windows I suppose). Just run the following command:

ipconfig /all

And you will get the status of every networking device on your computer (and their respective IP's). Or you can run winipcfg as mentioned above by astaec.


You could also run a traceroute to each of the sites and see where the jumps differ. Just run these commands:

traceroute www.privacy.net
traceroute www.whatismyipaddress.com
traceroute megawx.aws.com
traceroute www.chamisplace.com
traceroute www.lawrencegoetz.com

And see what kinds of paths it takes. It is no good that I run them from over here because it would not resolve your question (I have a static IP). Doing this might, or might not tell you something about the different IP's and if it is due to a geographical matter.

For a nicer traceroute you can use Neotrace:
http://www.neoworx.com/download/download.asp?product=NeoTrace

It's a graphical traceroute and you can see the trace displayed on a map.

Just a security advice:
As noted by Asta, Never post your real IP for people you do not know. Since I am working and have worked with security issues, I can tell you that I can find out who you are and where you live and what phone number you have, etc.(everything about you) by simply knowing that your DNS is 64.12.96.XXX
One other risk is that you get attacked by hackers or net attackers. Giving out your IP address to hackers is like giving a thief the key to your house.
That is a real problem for people in "Chat lines" and "ICQ" since many times anybody can find your IP and make trubles. That is one reason that many people,even usual people are seeking more and more help to Spoof their IP.(hiding or falsify IP address)
Actual IP address is not just numbers. Your actual IP address is "spider-mtc-tg051.proxy.aol.com"
64.12.96.XXX is the DNS.
The xxx part of the DNS is not important because as noted, dynamic dialup servers will give you new CCp numbers each time you connect. What is important is your domain address and pool address:
Good luck guys

Just to clear up a comment by Navid:
"Actual IP address is not just numbers. Your actual IP address is "spider-mtc-tg051.proxy.aol.com"
64.12.96.XXX is the DNS."

The IP address of any system is in fact the dotted quad numbers in the form of 64.12.96.####.  DNS or Domain Name System is the means to resolve to this IP address using a hostname.domain.name combination.

In the case of dynamic allocations of IP address the ISP assigns the IP address and the hostname.domain.name address assigned to the system each time a connection is made and these may change.  The hostname.domain.name assigned by the ISP is the one visible on the Internet and will not have any bearing on any local settings.  It is possible to assign the system an alternative hostname.domain.name to the ISP assigned IP address using Internet connected Name Servers.

In this particular case, the web browsing is obviously being done through proxy servers and LR141 has explained that.

Wouldnt surprise me if the Different IP addresses
are caused by the proxy servers Cache.

Marko, you do have an IP between you and AOL but for the purposes of these programs which can detect the IP you are using frmo the internet such as ICQ, the IP address is that of the PROXY server not your machine.  Unless things have changed and they do.  Ususally with AOL, you establish a Dial up network address to their server and use their proxies to get pretty much everything.

Yes that is exactly correct!! because they are using "Round Robin" configuration for network load balancing.  You were connected to AOL's Proxy server. They can have mutiple IP address for the same server.

Anyway, DHCP can be performed a variety of ways.  Not only does it enhance security, but it can enhance your speeds.  Here's how.  If you call up you can be assigned an IP from a pool.  Since you may not get the same IP each time you connect, your system is more secure(this is not spoofing but a real assigned IP).  The same goes for the router or proxy server that AOL may be using for your connection to websites.  You may get a different IP address each time.  I use a cable modem that has enabled DHCP.  I will always get the same IP address each time I hit Winipcfg until they need to expand their system or rework the routing table.
   The effects of DHCP are at least two-fold.  Firstly, you can maintain a consistant connection and data transfer rate as with all Microsoft OSs since Windows 95 they support your ip address changing several tinmes a minute.  What this allows for is for your connecting server to reroute your data to follow a route that gives the path of least resistance.  This helps insure that your data will not be slowed down if a particular server reaches its point of saturation.  Secondly, this adds security.  THIS IS NOT SPOOFING, but your system can be assigned an IP from a pool usually of 255 possible ones.  As you may have noticed that you are usually getting assigned an IP from these sites that follows the pattern 64.12.96.X.  More than likely that is just a server as AOL would definitely have more than 255 subscribers in your calling area.
     I have a cable modem which goes through a Cable/DSL Router Firewall.  When I went to these sites it gave me all the info I got from my router, not my PC.  Since I am sharing my IP the router assigns me my own IP addresses for the computers here on my network, but when I go run WINIPCFG I get my true IP address for my computer.
     I did find it interesting that I could not hit my back button after visiting one of your sites to get back to the data I had written.  Usually, I can do that.  It even cased something else rather unusual here.  My system locked up totally, and would not even respond to the three finger salute.

True with a shared Cable/DSL modem you would only get the address of the gateway (the modem itself).  I tried going to those site and got the actual address of my system.  I am also on a cable modem.

If your are behind a firewall or running firewall software it may only be broadcasting the ip address of the of modem or even further down line.

There system more likely during the traceroute only do so many hops.  The restriction of the number of hops could bring it to different location within the network.

There could be many reasons.

I do agree.  You should not make you ip address know here.  This could give someone the point the need to access you system, anyone else with you ISP or even your isp servers as well.
