What distinguishes a static IP-address from the dynamic?Said first never changes, whereas the latter changes at each new connection.Type of IP-addresses is determined by the provider and depends on the connection type you use.In the wired Internet, he often (but not always) a static - that is assigned only once and does not change even if you turn off the computer.
In that case, if you use USB-modem, IP-address is dynamic.When you connect your allocated free address range of provider-owned, while in the server logs, through which the connection information is recorded on how, to whom and at what time was assigned to the IP-address.When using the USB-modem is possible, for a fee, to get a permanent addres
To determine your IP-address type, go to one of the services that provide similar services, such as site At the top of the page you will see your currentnetwork address.Write it down, and then disconnect from the Internet, and wait a few minutes.Then reconnect to the Internet, go to the above services, and check the same record.If it is one and the same, then your IP-address is static.If the record has changed - it is dynamic.
Do the advantages of static or dynamic addresses?Static address need someone who is on your computer, open resources - for example, set your ftp-server.If you are a site administrator, it allows you to configure a static address entry to a resource for binding to IP-address, which significantly improves safety.
Lack static address that the attacker, knowing it can methodically pick "master key" to your computer.Since the IP-address does not change, it has an almost unlimited time to break.In this respect, much safer it is a dynamic address changes each time you reconnect.
