To reset your IP address

2009-12-31T06:39:00.000-08:00

we can reset our Ip address by using command prompt

An Internet Protocol (IP) address is a numerical label that is assigned to devices participating in a computer network utilizing the Internet Protocol for communication between its nodes.[1] An IP address serves two principal functions in networking: host or network interface identification and location addressees

command line

To find out your ip address you can type ipconfig

if your internet connection is not working or itz showing you limited area connection

so you can use your commad ipconfig/release

ipconfig/renew

we you type release then our ip address will get flush out

when we type renew the our ip addresss will get reset

ipconfig/release all

the renew all along dns alsoas itz use when bhanding problem comes

and some option like

/flushdns-then resolve the DNS caches

/registerdns- refreshes all DHCP leases and re-register DNS name

/DISPLAYdns-display the dns resolver caches

/SETCLASSID-display all DHCP CLASS IDs allowed for adapter

original designers of TCP/IP defined an IP address as a 32-bit number[1] and this system, known as Internet Protocol Version 4 or IPv4, is still in use today. However, due to the enormous growth of the Internet and the resulting depletion of available addresses, a new addressing system (IPv6), using 128 bits for the address, was developed in 1995[3] and last standardized by RFC 2460 in 1998.[4] Although IP addresses are stored as binary numbers, they are usually displayed in human-readable notations, such as 208.77.188.166 (for IPv4), and 2001:db8:0:1234:0:567:1:1 (for IPv6).

The Internet Protocol also has the task of routing data packets between networks, and IP addresses specify the locations of the source and destination nodes in the topology of the routing system. For this purpose, some of the bits in an IP address are used to designate a subnetwork. The number of these bits is indicated in CIDR notation, appended to the IP address, e.g., 208.77.188.166/24.

With the development of private networks and the threat of IPv4 address exhaustion, a group of private address spaces was set aside by RFC 1918. These private addresses may be used by anyone on private networks. They are often used with network address translators to connect to the global public Internet.

The Internet Assigned Numbers Authority (IANA) manages the IP address space allocations globally. IANA works in cooperation with five Regional Internet Registries (RIRs) to allocate IP address blocks to Local Internet Registries (Internet service providers) and other entities.

IPv4 subnetting

In the early stages of development of the Internet Protocol,[1] network administrators interpreted an IP address in two parts, network number portion and host number portion. The highest order octet (most significant eight bits) in an address was designated the network number and the rest of the bits were called the rest field or host identifier and were used for host numbering within a network. This method soon proved inadequate as additional networks developed that were independent from the existing networks already designated by a network number. In 1981, the Internet addressing specification was revised with the introduction of classful network architecture.[2]

Classful network design allowed for a larger number of individual network assignments. The first three bits of the most significant octet of an IP address was defined as the class of the address. Three classes (A, B, and C) were defined for universal unicast addressing. Depending on the class derived, the network identification was based on octet boundary segments of the entire address. Each class used successively additional octets in the network identifier, thus reducing the possible number of hosts in the higher order classes (B and C). The following table gives an overview of this now obsolete system.

introduction of dos

INTRODUCTION OF DOS

Dos is the real inverter of very software even windows is base on dos command every software

even c-programing ,java,flash-scripting but there are similar to c-programing

dos(disk operating system )

scripting

OS by default provides a primitive ability for shell scripting, via batch files (with the filename extension .BAT). These are text files that can be created in any DOS text editor, such as the MS-DOS Editor. They are executed in the same fashion as compiled programs, and run each line of the batch file as a command. Batch files can also make use of several internal commands, such as goto and conditional statements.[4] gosub and simple arithmetic is supported in some third-party shells but can also be faked via strange workarounds; however, no real form of programming is usually enabled.

The operating system offers a hardware abstraction layer that allows development of character-based applications, but not for accessing most of the hardware, such as graphics cards, printers, or mice. This required programmers to access the hardware directly, usually resulting in each application having its own set of device drivers for each hardware peripheral. Hardware manufacturers would release specifications to ensure device drivers for popular applications were available. command prompt drive naming

bootcfg:

bootcfg addsw

Adds operating system load options for a specified operating system entry.
Syntax

bootcfg /addsw [/s Computer [/u Domain\User /p Password]] [/mm MaximumRAM] [/bv] [/so] [/ng]/id OSEntryLineNum
Parameters
/s Computer
Specifies the name or IP address of a remote computer (do not use backslashes). The default is the local computer.

/u Domain \ User
Runs the command with the account permissions of the user specified by User or Domain\User. The default is the permissions of the current logged on user on the computer issuing the command.

/p Password
Specifies the password of the user account that is specified in the /u parameter.

/mm MaximumRAM
Specifies the maximum amount of RAM that the operating system can use. The value must be equal to or greater than 32 Megabytes.

/bv
Adds the /basevideo option to the specified OSEntryLineNum, directing the operating system to use standard VGA mode for the installed video driver.

bootcfg clone

On Itanium-based computers, creates a copy of an Extensible Firmware Interface (EFI) boot entry for use in a mirrored boot volume.
Syntax

bootcfg /clone /tg GUID [/sg GUID | /id bootid [/d description | /d+ description]] [/upddrv]
Parameters
/clone
Creates an EFI boot entry for a mirrored partition containing a Windows operating system.

/sg GUID
Specifies the globally unique identifier (GUID) of the partition containing the operating system from which the boot entry is being copied.

/tg GUID
Specifies the globally unique identifier (GUID) of the partition containing the operating system for which you are creating the cloned boot entry.

/id bootid
Specifies the boot entry to be copied.

/d description
Applies the specified friendly name to the cloned boot entry.

/d+ description
Appends the specified text to the existing friendly name for the boot entry specified with the /id parameter. When /d+ is used with the /sg parameter, the specified text is appended to the string, (clone).

/upddrv
Updates the device path to the EFI drivers.

/?
Displays help at the command prompt.

Examples

The following examples show how you can use the bootcfg /clone command:

bootcfg /clone /tg GUID /d+ test

Recommended when you have one EFI partition to clone from. It is best to use explicit arguments when you have multiple EFI partitions with multiple EFI partition boot entries to avoid confusion.

bootcfg /clone /sg GUID /tg GUID /d+ description

Recommended when you have multiple EFI partitions with multiple boot entries for each partition.

bootcfg /clone /tg GUID /id bootid /d description

Only clones the entry from the /id argument. This switch is useful if you have an EFI partition with multiple entries and you only want to clone one entry (not all entries). If you want to clone all entries from an EFI partition, use example 1 or 2.

bootcfg /clone /upddrv GUID

Only updates the floating point driver. No new boot entries will be added as a result of /upddrv. This switch is used if you add a new floating point driver to one EFI partition and you want to update the floating point driver on the other EFI partition.
bootcfg copy
