difference between static ip and public ip?

Answer 1

When you get internet service and get online your connection is automatically given an ip. IP stands for Internet Protocol. Think of it as your home address. Public ip is given at random, sometimes it will remain the same for a period of time, sometimes it will change each time you get online. You can find out your ip address by going to www.whatismyip.com
Certain programs you might be a member of might require you to have a permanent address so they can recognize your computer. A static ip will remain the same each time you log on. Generally your internet company will charge you more for a static ip, because they can not use it for different people. Internet providers dont' have an unlimited number of ip's to assign. They have blocks of numbers, and they reuse them. This is why if on dialup, you would get a busy signal when trying to get online. There are not enough connections to go around.
Hope that helped you to understand a bit better.

Answer 2

In a nutshell, when talking about IP addresses, public and private refer to accessibility. Static and dynamic refer to method of allocation.

Here's the longer answer.

An IP address is kind of a 'house number' for your computer on the Internet. It is how everything else knows where to send information to. It is 4 sets numbers 0-255 separated by periods. XXX.XXX.XXX.XXX, an example would be 45.89.235.49

If you are on the Internet this address would be considered 'public' – other computers on other networks can talk to you, and there is some backend routing information associated with it. A public IP would look like the example given above, and be (mostly) all other possibility other than what is considered 'private IP space'

If you are on a home/office network without Internet access you (in a properly configured network) have a 'private' address. Only computers on your network are able to communicate, and (generally) there isn't any routing going on. These would be:

10.0.0.0-10.255.255.255
127.16.0.0-172.31.255.255
192.168.0.0-192.168.255.255

There are two ways an ISP will assign an IP. One is 'statically' the other is 'dynamically'.

A 'static IP' does not change when you connect to the Internet. This would primarily be used if you were running a server, or required other people to be able to access your computer on the Internet without much hassle.

A 'dynamic IP' does change, using a process called DHCP (dynamic host configuration protocol) This is the most common method used by ISPs. For most users this changing IP is fine, and has no effect on your Internet access. Even cable providers are dynamic, although in my experience, the IP you are given seems to last quite some time.

Answer 3

As the other answer says, you can compare static and dynamic, or public and private.
A static IP is one that does not change.
Dynamic IP's change at some interval -- though the interval can vary.

Public IP's are IP's that are routable on the internet, for the most part.

Private IP's are ones that are not routable on the internet -- they are intended for private networks (such as a home office).

Answer 4

Static IP addresses are used for shared resources such as Web servers and Webcams.
while
an IP address can often be used to identify the region or country from which a computer is connecting to the Internet. An IP address can sometimes be used to show the user's general location.
it looks something like 127.0.0.1

Answer 5

It's static versus dynamic, not public.
A static IP stays always the same, a dynamic IP can change every time you log back on again (but may not).
