How come I get conflicting IP addresses on my local network? 

by on October 31, 2010

Q: Is it possible to see the sites from another computer on your local network after having an IP conflict?

Here’s what happened…

I opened my browser today and was told that I had an IP conflict with another computer on the network. I’m deployed and share a LAN with about 13 other guys on the same router. I closed the warning, released the IP address (forgot to renew it, however) and went about my business. Later that day, I opened facebook and I was logged into the page of another guy who is here on this same LAN.

This isn’t the first time this has happened; I was once approached by a guy here, who knows nothing about computers, who asked me if I’d been in his room on his computer, because I was logged into facebook on his as well. I really didn’t believe him, but I guess this proves it.

I’ll add that I know my releasing the IP and forgetting to renew it isn’t the cause, because of the time this happened in the past. Also, my job here is that of “computer guy,” so it’s my responsibility to figure this out. Any help would be greatly appreciated.

 
 

How come my router skipped an IP address? 

by on October 10, 2010

Q: I’m a noob so please bear with me. I use a linksys router which is assigned an IP ending with 1.1.

This morning, I checked my own IP and it ended with 1.3. I’m confused because I’m the only one using the connection (as far as I know). Where do you think 1.2 could have been assigned?

Right now, my IP ends with a 1.2 so I’m wondering if there could have been a compromise this morning or if the router could have addressed it elsewhere?

Things that can be done to an IP 

by on May 24, 2010

Q: Can someone check my computer’s Internet history using my IP address?

A: We get a good number of questions related to IP addresses and what people can do if they have your IP address so lets get to the bottom of what an IP address really is. An IP address is very similar to a phone number. This implies you can do almost anything to an IP address that you can do to a phone number. The first and simplest thing is you can try to call up the phone number/IP address and see if it responds. Read the rest of this entry »

Do not expect privacy on the Internet 

by on April 1, 2010

Q: Can somebody find out who I am by my IP address? Like if I went on a message board and my IP was listed on my post?

A: The Internet is like writing a letter to someone. You really have no idea where it will end up, who will see it, and when it will come back to bite you in the butt. Some people have a misconception that the Internet is more like chatting with a friend where there is no real record of you saying what you said but that isn’t how the Internet works. The minute something is put online it is there forever. There are hundreds of search engines that parse the Internet every second to get all new information and record it.

Changing Internet service providers causes IP address to change 

by on March 20, 2010

Q: If I change my Internet service provider would my IP address change?

A: IP addresses are much like phone numbers used to be where they are assigned to specific businesses/organizations and are not portable. Phone numbers, however, have moved into the 21st century and are now portable but currently IP addresses are not. There are many reasons why IP addresses are not portable but that is for a different discussion. Read the rest of this entry »
