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 http://www.ip-1.ru/ 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.
