What are US IP addresses?
For the majority of users, all you need to know is the IP address.
It's a unique number that identifies you in the internet, and the same number shows up on every website and app you use. It's also how email servers know your computer's exact location in the world, so sending emails to one of those addresses will get the intended recipient to their inbox no matter where they are. To explain all of these things in a quick video, we've created a step-by-step guide.
How does someone get my IP address? The first thing someone would have to do to get your IP address is ask you for it. You'd be the one who'd find it handy, so it'd be no surprise if someone asked you for it in a public setting, like online. On computers, this happens when websites are visited or applications are used.
What if I don't want someone to know my IP address? If you don't want your computer to tell people that it's connected to the internet, you can use anonymous proxy. These proxies work by relaying your IP address through a network of other computers. A service like FreeWebProxy.net creates a proxy in one location (eg, from a school or business network) and forwards it to your computer. The main benefit of this is that the connection will still be accessible in your location, but no IP address is available for anyone to find.
Are IP addresses the same everywhere? In theory, yes. But practically speaking, the routing of data around the world changes, often on a random basis. It's actually common for IP addresses to change even in a single city.
But. Why would anyone need an IP address anyway? This is the important part of understanding what an IP address is. An IP address doesn't just identify you as a person -- it's the unique address of your computer on the internet. This means it can point to your computer at any given time. Think of it as the phone number of your internet connection. You can always contact it, wherever you might be in the world. This is critical to any online activity that involves your computer, including chatting or web browsing. For example, Facebook users can reach out to any of the Facebook users on their list, because the users are all reachable using an IP address.
Is 192.168 255.255 a public IP?
I was wondering if it's possible to use the IP range 192.
168.255.0/24 as a public IP for an Amazon EC2 server?
The reason is that I don't know how to set up a static IP on my EC2 instance and then forward it to a port on my server where it will be accessible by the public internet. When I run my IP address through the lookup tool at and compare it to the IPv4 ranges listed for subnets, it shows that there are no records for any addresses in the range. Is there some way to set this up? The reason I'm doing this is that I want to be able to access the server from outside my local network using my personal home computer. I can already SSH into my EC2 server and the IP address that is reported is not a public IP.
Re: 192.168 255.255 a public IP?
Thank you for your response. I am aware that it is possible to setup a static IP for my EC2 instance. However, I do not want to use a public IP and I don't want to assign a private IP either since I will have my home computer connect to it. I was wondering if it was possible to setup a public IP like that instead of setting up a static IP.
The reason I am trying to get it set up this way is because I can't set up a static IP to my EC2 server since I don't have a static IP in my home network. The thing that confuses me is the IP that I get from the ec2 instance when I run it through the lookup tool. The result is that the IP appears to be public but it is not on the list for subnets.
If there is no way to do this, please let me know. Thanks again for your help. If I missed something or if you need any additional information, please let me know. So you don't have a static IP, and you don't want one? If that's the case you can setup an Amazon Route 53 Hosted Zone.
