The ip address that you have posted is not the static ip you have purchased. Before I start talking about the static ip, I should explain to you somethings regarding ips.
First of all, the address you have linked to, is your local network ip address. This may be static (your router or otherwise dhcp server may be assigning you the same internal network address) or dynamic (meaning that it changes between set intervals, or that it changes everytime your computer logs in and out of the network). That ip address is only useful to you if you would like your computer to communicate with other computers in the SAME network (be it a home network, or an enterprise network). Other than that, that ip address is only useful to you when you might want to set up port forwarding in your router. Your router is the only device that makes heavy usage of your ip address during an activity called NAT.
Secondly the public Ip address (which is what you are seeking), is what your router is using, in order for your internal network to be able to communicate with the Internet. The public Ip address may too, be dynamic (changing at set intervals, or at certain events, like resetting your router etc), or static (which is what you have bought). Static means, that if your network's ip is something like, (example) 143.72.94.54 it will stay like this, for as long as you have agreed with your ISP. This is certainly a convenience, as you know where your network is, and you can access the computers from any part of the world, using that IP address. For instance, you might be able to remote connect via SSH to do some administration to a computer inside your network.
Right now, you should have a question: What if I have several computers inside my network? What if I have 5 computers, all connected to the internet. And most importantly, how do packets reach them, If I only have one Ip address, and several computers listening on the same port?
And that takes me to the part where I explain NAT. NAT is an acronym for Network Address Translation. NATing is an activity your router uses to multiplex several computers connectivity and allow them to use network services simultaneously. For instance, let's say that you have 3 computers that are using a web browser and are accessing several web pages each time. How do the web servers know which computer asked for each website? SPOILER: They don't. What happens is that your router translates each computer's port and internal ip to a unique public port and ip address.
For a better explained example, look at the following:
Let's suppose you have a network with public ip 143.72.94.54, 3 computers, each with its own internal ip, and suppose that each one of them is using port 32 to access a web page
- Computer a: 192.168.1.2 : 32 -> http request to www.facebook.com -> 143.72.94.54:32 (?)
- Computer b: 192.168.1.3 : 32 -> http request to www.superuser.com -> 143.72.94.54:32 (?)
- Computer c: 192.168.1.3 : 32 -> http request to www.youtube.com -> 143.72.94.54:32 (?)
Since your network has only one ip, communication would seem impossible as all computers would race to get access to port 32 of the router, and only one of them could use it. So two of the computers would not get access to the required service.
That's where NAT steps in and translates internal ip addresses to external ones like this (and vice versa, of course):
- Computer a: 192.168.1.2 : 32 -> http request to www.facebook.com -> 143.72.94.54:64
- Computer b: 192.168.1.3 : 32 -> http request to www.superuser.com -> 143.72.94.54:876
- Computer c: 192.168.1.3 : 32 -> http request to www.youtube.com -> 143.72.94.54:987
Now all computers can have reliable services.
Now regarding your questions:
- You should be able to see your ip (and some more info): here
- This is the modem address, and the address your router uses to route packets outside your local network. The ip address your router uses for internal network communications commonly is something like: 192.168.1.1 EDIT: In your case it appears to be
1.2.3.62.
- There are 2 levels of gateways, local (your router perhaps) and remote (your isp's routers)
Hope that helped.
