Question about IP addresses?

[thecoalman]

So what is everything that CAN be seen by someone online, when I log into a forum for instance?

User agent (e.g. IE7), OS, and your IP. You can't hide your IP. Exception is if you're using a proxy but the proxy can still see your true IP.

Both by a MOD/ADMIN.... I'm pretty sure members can't see anything just like me.

A default installation of phpbb records the ip for every post made. There's a icon near the Quote and reply buttons to acess it which both the admin and mods can see. It can't be seen by regular users.

somebody knowing your ip isnt a threat in itself-- WAN or LAN ip. to see what your browser might be revealing to a website visit these links:

I think you all missed the point of NiteLite's post about Google. I don't think he was concerned about ads so much as the search results all come from people selling something as opposed to white paper information about the search subject. The solutions listed will block advertisements, but they won't stop search results showing vendors.

Just wanted to say that gadgetguy is exactly correct with my point and post info.
I didnt realize it could be taken different ways. Sorry about that.
But it is my findings that the search results are more ad based than info based depending on the search.
Thanks gadgetguy for the help.

But it is my findings that the search results are more ad based than info based depending on the search.

Any ads on the search page itself are clearly marked as advertisements. e.g sponsored links. If you're referring to where the non-sponsored links lead to that's another story itself. Google claims that the results are what they are, they don't manually place anything and I tend to believe that Try doing a Google search for Search, search engine or best search engine... . They will however remove sites if they don't fall within Googles guidelines such as using hidden text, cloaking etc. You can report such pages yourself: http://www.google.com/contact/spamreport.html

What if my IP changes?

These were some of my IP addresses over the past week:

72.92.2.22

72.94.91.211

72.92.115.61

72.94.90.97

72.94.206.246

Is there any pattern that says this is me?

vBulletin Version 3.6.7

A default installation of phpbb records the ip for every post made. There's a icon near the Quote and reply buttons to acess it which both the admin and mods can see. It can't be seen by regular users.

The site I'm mainly concern with uses vBulletin Version 3.6.7.

I don't know anything about vbulletin but phpbb records the IP of every post, it also provides information for the IP's used by member in previous posts or if another username has posted from that IP. I'd assume vbulletin would provide the same info.

Or simply add the following lines to your HOSTS file in c:\windows\system32\drivers\etc

127.0.0.1 pagead.googlesyndication.com
127.0.0.1 pagead2.googlesyndication.com

That will take care of Google ads ANYWHERE! I also recommend:

127.0.0.1 clickserve.cc-dt.com
127.0.0.1 ad.doubleclick.net
127.0.0.1 ln.doubleclick.net
127.0.0.1 ebay.doubleclick.net
127.0.0.1 paypalssl.doubleclick.net
127.0.0.1 m.doubleclick.net
127.0.0.1 m1.doubleclick.net
127.0.0.1 m2.doubleclick.net
127.0.0.1 m3.doubleclick.net
127.0.0.1 m4.doubleclick.net
127.0.0.1 m.2mdn.net
127.0.0.1 m1.2mdn.net
127.0.0.1 m2.2mdn.net
127.0.0.1 m3.2mdn.net
127.0.0.1 m4.2mdn.net
127.0.0.1 us.ebayobjects.com
127.0.0.1 uk.ebayobjects.com
127.0.0.1 fr.ebayobjects.com
127.0.0.1 de.ebayobjects.com
127.0.0.1 it.ebayobjects.com
127.0.0.1 nl.ebayobjects.com

as Doubleclick is now owned by Google.

Thanks mate for the list. Do you think you can post something to block yahoo adds?
Thanks

Or simply add the following lines to your HOSTS file

There are some long block lists available if you want to do this:

RoundTop,

You've asked some good questions and received some good anwers. Though I have to ask, what is it that you're trying to do or fix?

[dphirschler]

This thread has a dangerously misleading undertone that your internal IPs can be seen through your router. Somebody correct me if I am wrong, but I believe that is impossible. Which is one reason why routers are so good at being a "firewall".

Furthermore, I was not aware that your MAC addresses are accessible through the router from the outside. Only the router's MAC should be visible... although I do not know how to acquire that info.

The feature that you are addressing is called NAT Network Address Tranlation. Not all routers have this feature(thought most do).
Routers have two types of ports - A port labeled Upstream or WAN and several local ports.
The Upstream port is connect to the Cable or DSL modem and is the Internet connection. The Local ports are where you connect you computers and other Ethernet equipment.
The router gets an IP address for it's WAN from the service provider. The router assigns an IP address and port number the equipment attached to each local port.
When a connection is made to a web site the site can only see the routers IP address and the port number associated with the computer that initiated the request. An external site can not see the IP addresses of the attached computers. Hence N.A.T.
Hope this helps.

I beleive there is JS script for that, haven't tested no will I. I's imgine it would set some alrm bells off if there is.

The router's login name and password can act as a locked door, However a locked door with the original key still in it is not very much security. Change the admin login and password, also any available user name and password.

Next, the ROM addresses for storage are known for most routers, so if someone really, really, really wanted to hack your security it could be done.

Closing down all externally accessable ports will help, using an IP forwarder will help, using additional router will help, using a PC as a router will help, but just as with locks and lock-pickers, there is no perfect security, other than yanking out the ethernet cable.
