What Is Dynamic IP & Static IP

[dulajs]

What Is Dynamic IP & Static IP? I never heard before!!! Pls give me a huge description!!!!!!Thank

[zCexVe]

Static-Whenever you login to net its the same IP.No matter what you have an IP for your own registered by your ISP. Dynamic-You have one of the IPs in the range owned by your ISP.Everytime you connect/reconnect your IP changes.

IP Address

An IP address (Internet Protocol address) is a unique address that certain electronic devices currently use in order to identify and communicate with each other on a computer network utilizing the Internet Protocol standard (IP)—in simpler terms, a computer address. Any participating network device—including routers, switches, computers, infrastructure servers (e.g., NTP, DNS, DHCP, SNMP, etc.), printers, Internet fax machines, and some telephones—can have its own address that is unique within the scope of the specific network. Some IP addresses are intended to be unique within the scope of the global Internet, while others need to be unique only within the scope of an enterprise.

The IP address acts as a locator for one IP device to find another and interact with it. It is not intended, however, to act as an identifier that always uniquely identifies a particular device. In current practice, an IP address is not always a unique identifier, due to technologies such as dynamic assignment and network address translation.

IP addresses are managed and created by the Internet Assigned Numbers Authority (IANA). The IANA generally allocates super-blocks to Regional Internet Registries, who in turn allocate smaller blocks to Internet service providers and enterprises

Static and dynamic IP addresses

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

Method of assignation

Static IP addresses are manually assigned to a computer by an administrator. The exact procedure varies according to platform. This contrasts with dynamic IP addresses, which is assigned either randomly (by the computer itself, as in Zeroconf), or arbitrarily assigned by a server using Dynamic Host Configuration Protocol (DHCP). Even though IP addresses assigned using DHCP may stay the same for long periods of time, they can generally change. In some cases, a network administrator may implement dynamically assigned static IP addresses. In this case, a DHCP server is used, but it is specifically configured to always assign the same IP address to a particular computer, and never to assign that IP address to another computer. This allows static IP addresses to be configured in one place, without having to specifically configure each computer on the network in a different way.

In the absence of both an administrator (to assign a static IP address) and a DHCP server, the operating system may still assign itself a dynamic IP address using Zeroconf. These IP addresses are known as link-local addresses. For IPv4, link-local addresses are in the 169.254.0.0/16 address range.

Uses of dynamic addressing

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.

Uses of static addressing

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

most of the tyms
static - ADSL
dynamic - dailup

is it correct???
whenever we connected to the internet via adsl connection the ip address change as i think.that means we are using dyanamic ip address,which is used by another connection earlier.when ever u diconnect from the net or whenever u power off the computer your used ip get free.then it is used by another person.

thanks :lol:

thx for the info

[AlienX]

is it correct???


not really. I mean not @ all :P

ADSL has both static IP & dynamic IP services. dial up in like 99.9999999 % of the times has dynamic IP. Only with special & high cost service types (VPN wage) u will get a static IP with dial up & I dont think for VPN dial up is a good solution.

ADSL & other broadband internet services (XDSL , WiMax) on the otherhand offers both static & dynamic IPs or a pool of IPs for a customer.

ADSL by default has dynamic IP ( the one we all use) static IP is something which wont change in differant time. dynamic IP changes on time & upon restarting the connection (restart router u get a new ip or when lease time expires U get a new ip )

Static IP packages are really expensive so unless you are hosting a web service like web site or email something like that you wont need that :)


Hope its clear now :)

what is good, dynamic or static??

[kalhan]

:yes: :yes: :yes: :yes: :yes: tx dude :yes: :yes:

[psyche]

what is good, dynamic or static??

Dynamic....

1. 'coz if you are into rapidshare downloading you'll be having to keep turning off and on the router to get a ip address. With a static you cannot.

2. you'll have better security in a way 'coz if you have static you'll make a hacker's work easy to find you

most of the tyms

Iam sorry but you are wrong. ADSL is dynamic IP and chanels PPP(point-to-point)protocol over A (PPPOA)and if its more than 2MB its its PPP over E(ethernet). Well both are dynamic unless you request for a static. Dialup uses only a modem-to-modem link and uses TP line.

Anybody correct me If Iam wrong.

[charmer]

Use dinamic DNS to keep in touch with your ever changing dynamic IP

eh mehe machang...

In Sri Lanka most of the time all are dynamic....

Meheth ithin only if you pay a little bit more you'll get a static IP.

thx 4 coments

i have one IP CAMERA which i can watch it from anywhere in the world ON MY PDA (when i have internet gprs on my pda)

my WAN IP (ex 80.37.xx.xxx.) is changing every week, so i need to set it up everytime on my pda (unless i update my wan ip via dyndns). so dynamic ip is not the best for that job (not like rapid share bonus :) )

many other servers and services need static ip to countinue without any problems
