If you are using a DialUp connection (Internet), you can be sure that your current IP address is dynamic. Even if for a few hours, or even days he will not change the organization of DialUp connections, the absolute majority of Internet service providers is such that it does not use static IP addresses for this kind of connections.
Another very reliable method of determining the static nature of your connection - see the appropriate level in the contract with the provider. Providing a static IP address is nearly always a paid service, so it is reflected in the contract for the provision of services. If you have access to online statistics, you can see the mark there. For example, to find out in your "personal office" Beeline, we must first go to the tab "Internet" and then click the link "Manage services". In the section "Available for connection services" is the corresponding row of the link ("Permanent IP address") and you can see paid for it. If desired, you can click this link and connect or disconnect.
To the above two you can add only one fairly reliable way to determine the type of your IP address - just call the support phone your provider and ask this question.
All other methods of determining accuracy are fifty-fifty, at best. You can see your current IP address in the connection properties, then disconnect from Internet and connect again. If the address in the connection properties will change, it will mean that you have it dynamic. But if you stay the same, it does not mean that it is static - if you are using a router, then the address in the properties will always be the same, because it is "internal" IP address, not the one that is used to access the Internet. Even if you are not using a router equipment provider assigns an address based on the current load on the lines, i.e. you may be given the same address for several hours, days, or even months. But he will remain dynamic, meaning that guarantees for any of the following connect to a network.
Advice 2: How to be with dynamic IP address
IP address is a primary network address of your personal computer on any network, including the Internet. Divide them into static and dynamic. If you plan to work in a global network, it is recommended to use a permanent IP address, that at any moment it was possible to communicate with your PC.

This is especially true of small settlements. If you have no way of using ISP change dynamic IP address, you can use an alternative.
Use the technology of dynamic DNS, which provides a persistent domain name for a personal computer with a dynamic IPaddress. The information on the server is updated in real time. This feature is quite common and provided by many dynamic providers. For example, companies DynDNS, no-ip, TZO, FreeDNS and others.

For example, can register on the website www.no-ip.com. For registration enter your personal information and create a password, also be sure to specify real email, on which you will receive letter with the activation.
Login to your DNS provider. To do this, log in with your username and password. Next, locate the toolbar section of the "Add host", enter in the "Hostname" any name under which it will be registered to your personal computer in the system. Specify this name in the DDNS settings of your router or modem. If you go out to the Internet directly from the computer, you will need to download special software.
Install a program that will allow you to obtain a permanent domain name. Enter the configuration data that you fill in the provider DNS. On the main window, mark the boxes next to hosts that match the given personal computer.
