I am trying to figure out 1) If I vote on a contest from four different devices in the same building do they all have the same IP address or not? 2)If I take an iphone to a different location will it's address change? 3) if I send an email to someone or post on their website can they trace it back to my actual name or know that the comment was sent from the same IP address as an entry in the contest was? (I might want to ask a question of the sponsor and not have them know I, the entrant, asked it. 4) is there a way to have your IP address changing? Thanks so much!
Glad you got the post to work.
All devices in the same building are most likely on the same IP address. The only way to know for sure is to visit our homepage from each device and make note of the IP.
Your phone could have multiple IPs depending on how it's used. If you have WiFi turned on, then the phone will grab the IP from the available network. Example, if you're at a coffee shop and have wifi enabled on your laptop and your phone and sign in to the coffee shops network then both devices will most likely have the same external IP (the one you see on our homepage). However, if wifi is disabled on your phone the IP will be assigned by your carrier which will be different from the coffee shop IP.
If you send an email to someone, the most they can get is your IP address and that will only be traceable back to your city. And that's not 100% accurate. However, if the content of the email is threatening or harmful in nature and the recipient turns over the email to law enforcement, then the cops can obtain the IPs information from your ISP....and they will have your physical address.
There are ways to change your IP address. https://www.whatismyip.com/how-to-change-your-ip-address/
1) It depends on the devices and how they are accessing the Internet. If it's 4 separate 3G 0r 4G devices, they would probably all have individual IP addresses. If the devices are using a single Internet connection through a router, they would all have the same IP but may be differentiated by the user agent identifier but how that might matter depends on the site you are accessing.
2) It may change and it may not. It depends on the service you have and how far the geographic difference is.
3) It depends on your email service and where you send it from. Google doesn't typically identify the true IP of the sender IF you send the email through their browser interface. If you use an pop3 or imap software such as Thunderbird or Outlook Express, your internal and external IP will most likely be included in the header.
4)That's a pretty vague question. It depends on the service you are using.
Now I have a question. How can someone justify cheating?
