[quote=alvin_bilian][b]Quoted from Wikipedia[/b] When a computer uses the same IP address every time it connects to the network, it is known as a Static IP address. In contrast, in situations when the computer's IP address changes frequently (such as when a user logs on to a network through dialup or through shared residential cable) it is called a Dynamic IP address [u]Uses of dynamic addressing[/u] Dynamic IP Addresses are most frequently assigned on LANs and broadband networks by Dynamic Host Configuration Protocol (DHCP) servers. They are used because it avoids the administrative burden of assigning specific static addresses to each device on a network. It also allows many devices to share limited address space on a network if only some of them will be online at a particular time. In most current desktop operating systems, dynamic IP configuration is enabled by default so that a user does not need to manually enter any settings to connect to a network with a DHCP server. DHCP is not the only technology used to assigning dynamic IP addresses. Dialup and some broadband networks use dynamic address features of the Point-to-Point Protocol. [u]Uses of static addressing[/u] Static addressing is essential in some infrastructure situations, such as finding the Domain Name Service directory host that will translate domain names to numbers (IP addresses). Static addresses are also convenient, but not absolutely necessary, to locate servers inside an enterprise. An address obtained from a DNS server comes with a time to live, or caching time, after which it should be looked up to confirm that it has not changed. Even static IP addresses do change as a result of network administration, however[/quote] yes I am aware of this, their difference and importance. but my question is that is dynamically changing of IP is the cause of the unstable connection speed? If no then whats the cause?? sorry about my noob question, just really curious why is this happening.

I got it now, not only the dynamic configuration is one of the cause of the unstable connection, also the server itself. the maximum bandwith of my ISP is one factor why this is happening. Every users that subcribes on same ISP shares same bandwith. Like kamandag said, the server is not dedicated to handle to many users at the same time. and about the dynamic IP, if you notice sometimes your connection lost for a few seconds. thats because the IP that is assigned to you is already expired and need to be change. It would take a few seconds to assign another IP for you. static IP has stable internet connection speed is just a pure myth. Its just unoticable because they have separate server. Only few goes for Static IP and means only few shares the server's bandwith. thanks for kamandag's POV and i figured it out.
