what designates what my IP is? the modem itself ?

Answer 1

Your Internet service provider either assigns a static IP address to your DSL, or Cable connection, or you get a different IP assigned by a dial up ISP each time you connect to the Internet.

Answer 2

Your internet provider assigns an IP to you. If you have dial-up, your IP almost always changes every time you log in. If you have an always on connection with a dynamic IP such as DSL or cable your IP is refreshed every 24 hours or so. If you have a static IP address, it is never changed.

Hope that helps!

Answer 3

An IP address (Internet Protocol address) is a unique number that devices use in order to identify and communicate with each other on a computer network utilizing the Internet Protocol standard (IP). Any participating network device — including routers, computers, time-servers, printers, Internet fax machines, and some telephones — must have its own unique address. An IP address can also be thought of as the equivalent of a street address or a phone number (compare: VoIP) for a computer or other network device on the internet. Just as each street address and phone number uniquely identifies a building or telephone, an IP address can uniquely identify a specific computer or other network device on a network.

An IP address can appear to be shared by multiple client devices either because they are part of a shared hosting web server environment or because a proxy server (e.g. an ISP or anonymizer service) acts as an intermediary agent on behalf of its customers, in which case the real originating IP addresses might be hidden from the server receiving a request. The analogy to telephone systems would be the use of predial numbers (proxy) and extensions (shared).

IP addresses may either be assigned permanently (for example, to a server which is always found at the same address) or temporarily from a pool of available addresses.

[edit]
Dynamic
Dynamic IP addresses are issued to identify non-permanent devices such as personal computers or clients. Internet Service Providers (ISPs) use dynamic allocation to assign addresses from a small pool to a larger number of customers. This is used for dial-up access, WiFi and other temporary connections, allowing a portable computer user to automatically connect to a variety of services without needing to know the addressing details of each network.

Users with a dynamic IP may have trouble running their own email server as in recent years services such as mail-abuse.org [1] have collected lists of dynamic IP ranges and blocked them.

Dynamic IP address allocation requires a server to listen for requests and then assign an address. Addresses can be assigned at random or based on a predetermined policy. The most common protocol used to dynamically assign addresses is Dynamic Host Configuration Protocol (DHCP). DHCP includes a lease time which determines how long the requester can use an address before requesting its renewal, allowing addresses to be reclaimed if the requester goes offline.

It is common to use dynamic allocation for private networks. Since private networks rarely have an address shortage, it is possible to assign the same address to the same computer on each request or to define an extended lease time. These two methods simulate static IP address assignment.

[edit]
Static
Static IP addresses are used to identify semi-permanent devices with constant IP addresses. Servers typically use static IP addresses. The static address can be configured directly on the device or as part of a central DHCP configuration which associates the device's MAC address with a static address

Answer 4

Nope, the modem specifies your MAC address, which should be printed on it. You're IP number will be handed out by your ISP on either an Ad-hoc basis or permanent.

Answer 5

your dhcp server designates what ip address you..(dynamic host configuration protocol) your ip is leased to you for 7 days and then renewed.....your isp desinates the range your ip falls into and the dhcp server assigns the specific ip you use to access the web...the modem only funnels the ip to your pc---oh and by the way...ip stands for internet protocol

Answer 6

Your Internet provider assigns you an IP address each time you log on.

Answer 7

I P stands for internet provider
so it is from your ISP
if you are using a modem then each outgoing line from the ISP would have its own address

Answer 8

Your IP adress is created by your internet service provide... For example.. aol, comcast, charter, net zero, earthlink and so on.

Answer 9

your Internet Service Provider.

Answer 10

Your ISP
