Difference Between Ipconfig And Ping Command


IP config means,(Internet Protocol CONFIGuration) It is a windows command line utility that is used to manage the IP address assigned to the machine it is running in. Used without any additional parameters, it displays the computer’s currently assigned IP, subnet mask and default gateway addresses. IPCONFIG has several command line switches (parameters) preceded with a slash (see list below). The Mac counterpart is IPCONFIG See NSLOOKUP and netstat.

In Windows, ipconfig is a console application designed to run from the Windows command prompt. This utility allows you to get the IP address information of a Windows computer. It also allows some control over your network adapters, IP addresses (DHCP-assigned specifically), even your DNS cache.

Using ipconfig
From the command prompt, type ipconfig to run the utility with default options. The output of the default command contains the IP address, network mask, and gateway for all physical and virtual network adapters.
The ipconfig window.
The ipconfig command supports several command line options. The command
displays the set of available options.
Ipconfig /all
This option displays the same IP addressing information for each adapter as the default option. Additionally, it displays DNS and WINS settings for each adapter as well as a whole host of additional information.
Ipconfig /release
This option terminates any active TCP/IP connections on all network adapters and releases those IP addresses for use by other applications. Ipconfig/release can be used with specific Windows connection names. In this case, the command affects only the specified connections, not all connections. The command accepts either full connection names or wildcard names. Examples:
ipconfig /release "Local Area Connection 1"
ipconfig /release *Local*
Ipconfig /renew
This option re-establishes TCP/IP connections on all network adapters. As with the release option, ipconfig /renew takes an optional connection name specifier.
Both /renew and /release options only work on clients configured for dynamic (DHCP) addressing.
Ping is a command-line utility, available on virtually any operating system with network connectivity, that acts as a test to see if a networked device is reachable.
The ping command sends a request over the network to a specific device. A successful ping results in a response from the computer that was pinged back to the originating computer.
What does Ping stand for?
According to the author, the name Ping comes from sonar terminology. In sonar, a ping is an audible sound wave sent out to find an object. If the sound hits the object, the sound waves will reflect, or echo, back to the source. The distance and location of the object can be determined by measuring the time and direction of the returning sound wave.
Similarly, the ping command sends out an echo request. If it finds the target system, the remote host sends back an echo reply. The distance (number of hops) to the remote system can be determined from the reply, as well as the conditions in-between (packet loss and time to respond). While the author of the ping utility said the name of the program was simply based on the sound of sonar, others sometimes say that Ping is an acronym for Packet InterNet Groper.
How does Ping work?
The Ping utility uses the echo request, and echo reply messages within the Internet Control Message Protocol (ICMP), an integral part of any IP network. When a ping command is issued, an echo request packet is sent to the address specified. When the remote host receives the echo request, it responds with an echo reply packet.
By default, the ping command sends several echo requests, typically four or five. The result of each echo request is displayed, showing whether the request received a successful response, how many bytes were received in response, the Time to Live (TTL), and how long the response took to receive, along with statistics about packet loss and round trip times.
Ping message format
The echo request ("ping") is structured as follows:
Byte 0	Byte 1	Byte 2	Byte 3
Type (8 = IPv4, ICMP; 128 = IPv6, ICMP6)	Code	Header Checksum
Identifier	Sequence Number
The echo reply must include the exact payload received in the request:
Byte 0	Byte 1	Byte 2	Byte 3
Type (0 = IPv4, ICMP; 129 = IPv6, ICMP6)	Code	Header Checksum
Identifier	Sequence Number
The Ping utility
The ping utility has been incorporated into virtually every operating system with network support. While echo request and echo reply are ICMP messages, the exact implementation of the Ping utility varies slightly among manufacturers.
In its simplest form, the ping utility can be run with nothing more than the ping command and a destination. The remote host can be specified either by name or address.
ping ftp.microsoft.com
The following is the output of a simple ping to the target host paessler.com:
ping paessler.com
Pinging paessler.com [] with 32 bytes of data:
Reply from bytes=32 time=4ms TTL=57
Reply from bytes=32 time=4ms TTL=57
Reply from bytes=32 time=4ms TTL=57
Reply from bytes=32 time=4ms TTL=57
Ping statistics for
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 4ms, Maximum = 4ms, Average = 4ms
However, the ping utility also provides several customizable options.
Ping switches and variables
There are numerous switches available for the ping command that allow the default settings to be customized for more specific purposes. Unfortunately, there is no consistency across platforms for the different switches. For example, Windows uses a -n (number) to set how many pings to send, while most Unix systems use a -c (count).
Here are some examples of ping command switches. Generally, using ping -?  will result in a list of switches along with the corresponding letter to use the switch on the operating system.
Number (or count) – sets the number of echo requests, or pings, to be sent. By default, this number is four on most Windows systems, and five on most Unix systems. Setting a higher number allows the ping to continue to run either as a way of gathering more data, for example, to see if the reply time varies, or as a way of ensuring that a system continues to be responsive.
Timeout – changes the timeout before the utility waits for a reply from the destination. On Windows systems, the default value is 4,000 milliseconds, or 4 seconds.
Size – changes the size of the ping packet. The default value on Windows is 32 bytes, many Unix/Linux systems default to 64 bytes.
TTL – sets a different TTL.
IP4 or IP6 – responds with IPv4 or IPv6 addresses. (ping -4/ping -6 in Windows, ping or ping6 in Linux)
Until stopped – keeps running the ping until stopped by the user (-t in Windows)
Ping command syntax for Windows
-t	Pings the specified host until stopped. To stop - type Control-C
-a	Resolve adresses to hostnames
Number of echo requests to send
-l 	Send buffer size
-f	Set Don't Fragmet flag in packet (IPv4-only)
-i	Set Time To Live
-v	Set Type of Service (Setting has been deprecated)
-r	Record route for count hops (IPv4-only)
-s	Timestamp for count hops (IPv4-only)
-j	Loose source route along host-list (IPv4-only)
-k	Strict source route along host-list (IPv4-only)
-w	Timeout in milliseconds to wait for each reply
-R	Use routing header to test reverse route also (IPv6-only, deprecated per RFC 5095)
-S	Source address to use
-c	Routing compartment identifier
-p	Ping a Hyper-V Network Virtualization provider address
-4	Force using IPv4
-6	Force using Ipv6
How to use Ping
For such a small, basic utility, the ping command can be a valuable tool in numerous situations. As a command-line based utility, ping lends itself to easy use in various scripts, allowing for numerous pings to run and be recorded for all manner of usage. For example, the output of the ping command can easily be piped to a text file for later review.
Troubleshooting with Ping
Perhaps the most common use of the ping utility is in troubleshooting. When trying to use applications or systems over a network, the most important thing to know is if there is actually a working connection. A series of ping commands can help determine what the problem is.
A quick ping by IP address will confirm that the system is on, that there is a connection, and that the two machines can talk to each other.
If the ping is successful by name and IP address, but the response times are long, there may be a routing, network speed, or congestion issue. Even unsuccessful pings can provide valuable troubleshooting information.
If a ping by IP address is successful, but a ping by name fails, then there is a name resolution issue. If the ping fails altogether, you can try to ping other parts of the network to isolate the issue. A successful ping of the default gateway confirms that the network connection is functioning, but that something is interfering with a connection to the remote system.
If you can ping successfully with the same subnet of the remote system, but not the target system itself, then the network connectivity of the remote host is in doubt. If the default gateway cannot be pinged, but the loopback address ( results in a successful ping, then you would know that the network interface is functioning, but there is no connection to the network.
Ping error
If ping gets no response from the target host, most implementations of ping display nothing or a timeout notification. The result may look like this, for example:
Pinging with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.
Ping can be used as a quick and dirty discovery tool. Since virtually any network connected device will respond to a ping, pinging a range of addresses, for example, would allow an administrator to find all the attached devices in that range, regardless of type of device or operating system.
Ping can be used to monitor the network availability of devices. A ping command running as a scheduled task can offer rudimentary polling of any networked computer or device without the need to install any additional software agents, and without the need to open additional ports. The most basic of any up/down monitor could be accomplished by running a ping with the ‘run until stopped’ option. When the pings start failing, there is an issue reaching the system.
Obviously, these solutions are greatly improved upon by the addition of a monitoring tool like PRTG, which, while using underlying ping commands, does not rely on someone watching the output, or piping the output to some sort of record.
The standard Ping Sensor runs ping commands in the background. These can be configured to run at specific intervals, or in response to another event. For example, if a sensor reports a connection failure, a ping can determine if there is still a network connection. Or, monitors can be configured to alert an administrator if ping times get too long, or if there is too much packet loss.
Another interesting ping-based sensor is the Cloud Ping Sensor, which pings monitored systems from a remote cloud of distributed systems. This provides the all-important, but difficult to detect, alert when everything is running just fine on your end, but for whatever reason, your systems are unreachable from the outside by remote users or clients.
Simply knowing a system exists and is connected to the network may be enough information for an attacker to begin. Careful analysis of ping replies may yield additional information such as which operating system the target is running, where the machine is located, and so on.
Many hacking tools take advantage of “walking the range”, by pinging every IP address on a targeted network to get a list of what systems are reachable and will respond. As a result, many firewalls are configured to block ping requests from untrusted networks.
Difference Between Ipconfig And Ping Command
IpconfigDisplays all current TCP/IP network configuration values and refreshes Dynamic Host Configuration Protocol (DHCP) & Domain Name System (DNS) settings. Used without parameters, ipconfig displays the IP address, subnet mask, and default gateway for all adapters. Ping Verifies IP-level connectivity to another TCP/IP computer by sending Internet Control Message Protocol (ICMP) Echo Request messages. The receipt of corresponding Echo Reply messages are displayed.
Ipconfig and Ping both are commands of command line interface (CLI) .IPconfig is used to display all network configuration values . Ping is used to check whether a host can send or receive packets.
